This document discusses challenges that national HIV treatment programs face in revising their guidelines based on the 2010 WHO recommendations. It highlights key changes in the WHO recommendations, including earlier initiation of ART at CD4 <350 cells/mm3, expanded first- and second-line regimens, and increased use of viral load and CD4 monitoring. While the scientific evidence supports these recommendations, resource-limited settings face challenges with adoption and implementation due to factors like limited funding and health systems constraints. The brief outlines lessons learned from countries in sub-Saharan Africa, Latin America, and Southeast Asia on successfully navigating the guideline revision process through measures such as streamlining procedures and prioritizing certain recommendations for initial implementation.
This document provides information from the HIV and AIDS Data Hub for Asia-Pacific on data availability and population size estimates of people who inject drugs, men who have sex with men, transgender people, and male sex workers across several countries in Asia and the Pacific region. It includes tables and charts with the countries where data is available from sentinel surveillance surveys, behavioral surveys, and population size estimates. It also provides references for the estimates and surveys.
The document summarizes HIV epidemiology among men who have sex with men (MSM) globally and in Asia Pacific. Some key points:
- HIV prevalence among MSM ranges from under 1% to over 25% depending on the country/region, with most of Asia and Africa over 5%.
- HIV is increasing among MSM in many countries as prevalence declines elsewhere, with urban areas often having much higher rates.
- Condom use and HIV testing is low among MSM in most areas. Criminalization and stigma also limit data collection and access to services.
- MSM population size estimates vary widely but are often in the hundreds of thousands to millions in Asia Pacific countries.
FINAL cervical cancer prevention mapping 2015Melani Montano
This document summarizes a study that mapped HPV vaccination and cervical cancer screening practices in the Pacific region. The study found that while cervical cancer prevention was seen as highly important, implementation of prevention programs was insufficient. Only two countries had screening coverage above 40% and two countries had HPV vaccination coverage above 60%. Key barriers to HPV vaccination included lack of sustainable financing, lack of government endorsement, concerns about vaccine safety, and lack of clear guidelines. The study concluded that current prevention efforts do not match the high cervical cancer burden and that a regional approach is needed to strengthen prevention programs.
HIV causes AIDS by attacking CD4 cells of the immune system. It enters cells through binding to CD4 and CXCR4/CCR5 receptors, integrating its RNA into the cell's DNA. This leads to increased viral load and decreased CD4 count over many years until opportunistic infections define AIDS. Globally, HIV has infected over 75 million people and claimed over 32 million lives since the early 1980s.
The document summarizes the key points from a quarterly review meeting of India's National AIDS Control Programme. It provides an overview of the program, highlights achievements in reducing HIV infections and AIDS-related deaths, and outlines the vision and targets to end AIDS by 2030. Key agenda items discussed establishing ART centers in all medical colleges, eliminating mother-to-child HIV transmission, implementing the HIV/AIDS Prevention and Control Act of 2017, and achieving the 90-90-90 fast track targets to diagnose and treat people living with HIV. Support was requested from states to help scale up HIV testing, treatment and care.
This document provides revised guidance for the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) on comprehensive HIV prevention for people who inject drugs. It endorses a package of three core interventions: community-based outreach programs, sterile needle and syringe programs, and drug dependence treatment including medication-assisted treatment. The guidance outlines evidence that these interventions can significantly reduce risky drug use behaviors and HIV transmission when implemented together in a comprehensive manner.
Dr. Angelo Consiglio owns and practices at Allergy Ear Nose & Throat near Key West, Florida, and also serves as a lecturer on oral cancer and related topics. Statistics show the risk of oral cancer increases after age 55 and is twice as high for men than women. Certain genetic mutations and lifestyle factors like smoking, drinking alcohol, a lack of fruits and vegetables in the diet, and prolonged sun exposure can contribute to higher risks of developing oral cancer.

This document summarizes constraints in effectively managing HIV/AIDS with antiretroviral (ARV) therapy in Nigeria. It discusses how ARV drugs are scarce and expensive in Nigeria, requiring strict medical supervision and often causing side effects, all of which can lead to non-compliance. It also notes that non-adherence to the drug regimen could result in drug-resistant strains of HIV, further complicating treatment. The document provides suggestions for how the government can help ensure adherence, such as making ARV drugs more available, affordable, and regularly supplied, and employing more trained medical personnel to administer the drugs.

It provides background on HIV/AIDS and drug use in Bangladesh, describing current interventions for IDUs that incorporate harm reduction strategies like drop-in centers and needle exchange programs. The proposed study will use qualitative and quantitative methods to assess current knowledge and behaviors of IDUs and evaluate community-based outreach programs to identify best practices for prevention.
HIV Epidemiology: Progress, challenges and Human Rights implications Vih.org
This document summarizes trends in the global HIV/AIDS epidemic and discusses the link between epidemiology and human rights. It finds that while new infections and deaths have decreased due to prevention efforts, human rights abuses continue to impede epidemiological understanding and response. Vulnerable groups like migrants, men who have sex with men, and injecting drug users face disproportionate risks due to criminalization and lack of targeted programming. Strengthening health information systems and promoting universal human rights access are seen as essential to further containing the epidemic.
HIV/AIDS data Hub Asia Pacific -Malaysia 2014Dr. Rubz
This document provides a summary of HIV/AIDS data for Malaysia across multiple indicators:
- HIV prevalence is highest among key populations like people who inject drugs, female sex workers, and men who have sex with men. Condom use and safe injection practices have increased over time but remain below optimal levels.
- The number of reported HIV infections and AIDS-related deaths has declined in recent years. Most HIV transmissions are through heterosexual contact and injecting drug use.
- Vulnerability remains high as many key populations lack comprehensive HIV knowledge and access to prevention programs, testing, and treatment.
- Government spending on HIV has increased but more funding needs to be directed towards programs for key populations at higher
This document provides a regional overview of HIV/AIDS trends in Asia and the Pacific from 1990-2013. It summarizes that there are currently 4.8 million people living with HIV in the region, with new infections declining significantly since 2001 but remaining largely unchanged in the past 5 years. Treatment coverage has increased substantially, with 1.56 million people now on ART, however this is still only about one-third of those in need. The challenges ahead include addressing gaps in prevention for key populations and along the treatment cascade.

This document summarizes a study on the use of herbal medicine in the management of malaria in Ghana. The study analyzed data from 189 malaria patients and 5 herbal medicine practitioners in the Kwabre East District of Ghana. The results showed that 95 (50.3%) of patients used herbal therapy for malaria treatment. Factors significantly associated with herbal medicine use included perceived lower side effects, cost-effectiveness, efficacy, and availability. Herbal practitioners were experienced with treating malaria and had extensive knowledge of medicinal plants. The study recommends further research on the safety and quality of medicinal plants used to treat malaria and other diseases.
This document summarizes key information about HIV in the United States:
- Over 1.1 million people are living with HIV in the US, with about 56,000 new infections each year. Rates are highest among men who have sex with men, African Americans, Latinos, and intravenous drug users.
- Effective prevention strategies include promoting abstinence, fewer partners, condom use, not sharing needles, antiretroviral treatment, male circumcision, and pre-exposure prophylaxis. Widespread testing is also an important prevention approach.
- Combining multiple prevention approaches and targeting high-risk groups can maximize the impact of HIV prevention and reduce transmission rates in the US.
Lymphatic filariasis is a disabling tropical disease spread by mosquitoes that causes swelling of the limbs and genitals. It impacts over 120 million people worldwide and is targeted for global elimination by 2020. Mass drug administration of medications that interrupt transmission has protected millions from infection and been delivered to over 2.8 billion people across 53 countries with support from the CDC and partners. While transmission continues in some parts of the Americas, regional elimination is achievable with sustained control efforts such as expanding treatment coverage and improving disease management.
FACTORS ASSOCIATED WITH HUMAN IMMUNODEFICIENCY VIRUS COUNSELLING AND TESTING ...Razak Mohammed Gyasi
Since 2003, the HIV Voluntary Counselling and Testing (VCT) has been identified as one of the key strategies in the HIV/AIDS prevention, control and care programmes in Ghana. However, utilization of this service is low among Ghanaian youth. This study examined predictors associated with VCT utilization among youth in Ghana. This study utilized quantitative and qualitative data in a cross-sectional survey in three sub-metropolitan areas in Kumasi. Using a multi-variate regression, evidence from 120 respondents showed potential factors associated with VCT utilization. The qualitative data were subjected to a content analysis through direct quotes. The results suggest that less than 30% of the youth had ever tested for HIV through VC. Women were more likely to avail themselves for counselling testing than men. Psychological and emotional trauma experienced by the seropositive, lack of confidentiality, proximity to VCT sites, HIV-related stigma inter alia, were found to be strongly associated with HIV VCT in the study prefecture. VCT utilization among the youth in Ghana was low and affected by HIV/AIDS-related stigma and residence. In order to increase VCT acceptability, HIV/AIDS prevention and control programs in the country should focus on reducing HIV/AIDS-related stigma.
There are an estimated 170 million people globally infected with hepatitis C virus (HCV), which poses a rising threat to healthcare systems. While some national governments and non-governmental organizations have accelerated efforts to improve HCV education, testing, and treatment, significant barriers remain. Effective disease surveillance is critical but data on chronic HCV prevalence is lacking in over half of countries surveyed. As awareness of HCV has increased, patient advocacy groups have played a leading role in shaping policy and pressuring governments to adopt more comprehensive national strategies. However, approaches to HCV still vary widely between countries.
The document summarizes the risk factors and prevention strategies of oral cancer in India. It finds that oral cancer is the most common cancer in India, accounting for 4 in 10 cancers. India has a high prevalence due to widespread tobacco consumption, especially gutka and quid. About 130,000 people die from oral cancer annually in India. Prevention strategies such as reducing tobacco consumption and early detection are needed to reduce the oral cancer burden.
The National Cancer Control Programme aims to control cancer in India through primary prevention, early detection, treatment, and palliative care. Key goals include preventing cancers caused by tobacco, screening and diagnosing cervical and breast cancers early, strengthening cancer treatment facilities, and providing palliative care. Over 8-9 lakh new cancer cases occur annually in India. The programme supports 27 Regional Cancer Centers, has developed oncology wings in 82 medical institutions, and runs 28 District Cancer Control Programmes.
1. The document summarizes Malaysia's HIV/AIDS situation and recommendations for interventions. It reports that while HIV transmission is declining overall, sexual transmission now accounts for over 50% of new cases, especially among heterosexuals and men who have sex with men. 2. Key recommendations include expanding access to antiretroviral treatment, strengthening prevention services for at-risk groups, and implementing proven interventions like condom promotion and harm reduction programs. 3. Achieving the UNAIDS 90-90-90 targets of diagnosing 90% of HIV cases, treating 90% of those diagnosed, and virally suppressing 90% of those treated is an important goal.
The document provides an overview of HIV/AIDS in India, focusing on what is known and what further data is needed for evidence-based decision making. It discusses HIV prevalence and risk factors in southern and northeastern states. While some data exists on high-risk groups like female sex workers, men who have sex with men, and injecting drug users, more systematic data collection is needed to better understand trends over time and inform targeted prevention programs. A rights-based, evidence-informed approach is critical to effectively address HIV in India.
IRJET- Epidemiology of Parkinson’s Disease in AfricaIRJET Journal
This document summarizes a review paper on the epidemiology of Parkinson's disease in Africa. The review examined 30 publications from 13 African countries. It found that overall prevalence and incidence rates in African regions are lower than American and European populations. No significant differences in prevalence were seen between men and women. Management of Parkinson's disease in most African regions is generally lacking, with deficiencies in diagnosis, treatment, medication, and supervision.
Dr. Nisrin Anfinan discusses challenges related to cervical cancer in Saudi Arabia. The incidence of cervical cancer in Saudi Arabia is very low at 1.9 cases per 100,000 women, accounting for only 2.6% of cancers in women. However, challenges exist in understanding the prevalence of HPV infections and abnormal pap smears in the population. Implementing an effective screening program will also be difficult without understanding sexual practices and managing sexually transmitted infections. Determining the most appropriate screening method and triaging patients will also be challenges.

Burden of HIV and Research Gaps Among Key Populations in Sub-Saharan AfricaHopkinsCFAR
Key populations including sex workers, men who have sex with men, and people who inject drugs experience disproportionately high HIV burdens in sub-Saharan Africa due to various biological, behavioral, and structural factors. HIV prevalence among female sex workers ranges from 10.9% in Eastern Europe to 36.9% in sub-Saharan Africa, where sex workers are 12 times more likely to be infected than other women. Men who have sex with men also experience high HIV prevalence, though data remains limited in sub-Saharan Africa. Combination prevention approaches including behavioral, biomedical, and structural interventions are needed to address the outsized impact of HIV on key populations.

The recommendations aim to provide guidance on when to start ART, what first-line regimens to use, when to switch regimens, and appropriate second- and third-line options. It also covers laboratory monitoring and other interventions that should be part of a comprehensive package of HIV care.
This document provides guidance for assessing and managing a child on their first visit when they have known exposure to HIV or are a sick child suspected to have HIV exposure. It outlines checking the mother's HIV status and other risk factors to determine the likelihood of infection and appropriate testing and treatment. Key decisions include testing all exposed infants, treating those confirmed positive, and regular follow up testing for those who test negative.
Module 4 hiv infection & art in childrenDavid Ngogoyo
This document provides an overview of managing HIV infected children. It covers the epidemiology and transmission of HIV in children, the natural progression of disease, diagnosis and staging, prevention and treatment of common HIV conditions, and antiretroviral therapy for children. Key points include mother-to-child transmission being the most common mode of transmission, diagnostic criteria involving virologic tests for children under 18 months and antibody tests after 18 months, and natural history patterns including rapid, intermediate, and slow disease progression in African children.
The Paediatric HIV Treatment Initiative (PHTI) to Speed Development and Avail...Medicines Patent Pool
At the AIDS2014 Conference in Melbourne, MPP Sandeep Juneja, Business Development Director at Medicines Patent Pool presented the Paediatric HIV Treatment Initiative (PHTI) and how it will speed the development and availability of needed formulations.
The document discusses the importance of addressing gender equality in Global Fund proposals and responses to HIV, TB, and malaria. It notes that women often have less access to health services and information than men due to social and economic inequalities. It provides examples of how diseases like HIV, malaria, and TB disproportionately impact women. The document advises applicants to involve gender experts and conduct a gender analysis to ensure their proposals address the specific needs of women, men, girls and boys. It also recommends integrating gender-sensitive and transformative interventions that promote human rights and reduce health inequalities.
This review examined the use of information and communication technologies (ICTs) like mobile health (mHealth) and telemedicine for breast and cervical cancer prevention programs in low- and middle-income countries. Of over 285 articles identified, only eight met the criteria. These articles described a few interventions using ICTs for cancer awareness, screening reminders, and remote diagnosis. However, they noted a lack of robust evidence on outcomes. While ICTs could potentially address barriers to cancer prevention programs like access and costs, more research is needed on their effectiveness in low-resource settings.
This document provides background information on HIV/AIDS and disease surveillance services. It discusses how HIV first emerged in the 1980s and has since spread globally. Disease surveillance involves the ongoing systematic collection and analysis of data to monitor disease spread and inform prevention and control efforts. The document then reviews studies on HIV prevalence in various countries and age groups. It also discusses theories relevant to disease surveillance and HIV control, including how education and awareness building can impact prevention efforts.
The Indonesian response for the HIV/AIDS Epidemic among and from Injecting Dr...Sketchpowder, Inc.
The document discusses the HIV/AIDS epidemic among injecting drug users in Indonesia and internationally. It provides three core interventions that can impact the epidemic: needle and syringe exchange, treatment for drug-related problems, and care, support and treatment for injecting drug users. The document also summarizes international experiences with harm reduction programs in Iran, China, and Brazil, noting their public health approaches, investments in addressing HIV/AIDS, and availability of antiretroviral therapy. Adherence to antiretroviral therapy among injecting drug users in Brazil was found to be similar to other international studies.
Global HIV cohort studies among IDU and future vaccine trialsThira Woratanarat
The author reviewed data on the global HIV epidemic among injecting drug users (IDUs) and identified potential cohorts of IDUs that could participate in future HIV vaccine trials. High HIV prevalence rates were observed among IDUs in many countries in Asia, Eastern Europe, Latin America, and parts of Africa and North America. Several cohort studies also showed high HIV incidence rates among IDUs in China, Thailand, Canada, and Spain. These findings emphasize the seriousness of the IDU epidemic globally and the potential for IDU cohorts to participate in HIV vaccine trials due to demonstrated high participation and retention rates in past studies.
The document discusses the history and current state of the AIDS epidemic in Africa. It begins by tracing HIV back to chimpanzees in Cameroon in the 1930s and its spread to humans. By the 1980s, AIDS cases rose sharply across Eastern Africa due to factors like labor migration. Treatment was not widely available until the 1990s. Currently, South Africa has the most HIV cases but prevalence has declined by a third over the past decade due to treatment programs. However, the number of people needing treatment is expected to exceed resources by 2020 without increased prevention and sustainable treatment options. More work is still needed to curb the epidemic.
AIDSTAR-One HIV Treatment Guidelines in Guyana - The Fast Track to Diagnosis ...AIDSTAROne
This case study details Guyana's process for revision of their national HIV treatment guidelines, based on WHO's 2010 revised recommendations . While many countries are still working to revise their national guidelines in response to WHO's latest guidance, the National AIDS Programme in Guyana has been implementing elements of WHO's 2010 recommendations since 2006.

This document provides background information on a WHO consultation regarding guidance on viral hepatitis prevention, surveillance, and treatment. It summarizes statistics on hepatitis B and C infections globally and among people who inject drugs. It also describes the negative impact of HIV co-infection on hepatitis disease progression. To inform the guidance, interviews were conducted with community members and healthcare providers affected by or working on viral hepatitis across various world regions. Their perspectives will provide insights into the individual challenges faced by those impacted by the guidance.
Today we stand at a vital threshold. Within our grasp is the opportunity to end 30 years of suffering and death due to HIV/AIDS. Individuals and communities around the world have been mobilized toward prevention, and existing treatment can prolong life for many years. While we celebrate these successes, we reject any modicum of complacency. Now is the time to double down and finish the job. The world is fighting AIDS today just as it had previously fought to eliminate smallpox. For centuries, smallpox was a feared scourge that killed nearly half of those infected and maimed those that survived. A worldwide campaign to end the disease began in earnest in the late 1960s and by 1980 smallpox was officially eradicated.
Planet Aid anticipates the day when AIDS, too, will be stopped. To this end, we have been helping mobilize communities around the globe to increase HIV/AIDS prevention and care. With this special issue of the Planet Aid Post, we focus on the battle ahead. We also extend a warm welcome to those joining us on the forefront of this work,

Cancer is a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body.
Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and multiply (through a process called cell division) to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place.
Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue. Tumors can be cancerous or not cancerous (benign).
Cancerous tumors spread into, or invade, nearby tissues and can travel to distant places in the body to form new tumors (a process called metastasis). Cancerous tumors may also be called malignant tumors. Many cancers form solid tumors, but cancers of the blood, such as leukemias, generally do not.
Benign tumors do not spread into, or invade, nearby tissues. When removed, benign tumors usually don’t grow back, whereas cancerous tumors sometimes do. Benign tumors can sometimes be quite large, however. Some can cause serious symptoms or be life threatening, such as benign tumors in the brain.

This document discusses the health needs of transgender people in Asia and the Pacific. It finds that their needs have been severely neglected, with limited data available. It recommends strategic actions including systematically collecting data on human rights violations like violence and discrimination experienced by transgender people. It also calls for training health workers on transgender health issues and developing guidance on hormone treatment, gender-affirming surgery, and caring for young and older transgender people adapted for resource-limited settings. The document should be used to raise awareness among transgender communities and policymakers to better address the needs of this population.
This document summarizes the AIDS epidemic in Eastern and Southern Africa and progress towards meeting international targets on HIV/AIDS. Some key points:
1) There are 34 million people living with HIV globally in 2011, with 1.2 million new infections in Eastern and Southern Africa. Several countries have reduced new infections by over 50% since 2001.
2) Coverage of prevention of mother-to-child transmission services was 72% in 2011 in the region. 5.2 million people were receiving antiretroviral treatment out of 8.1 million estimated to be eligible.
3) Reducing sexual transmission by 50% and reaching 15 million people on HIV treatment by 2015 are among key global targets, but
While the world has focused on the traditional causes of premature death in Africa – communicable diseases such as HIV, malaria and tuberculosis, malnutrition, road and other accidents and political conflicts – a column of other types of killers has been gaining ground.
These are the chronic, noncommunicable diseases (NCDs) such as cancer, heart disease, diabetes, sickle-cell disease and kidney disease, whose collective toll is rising rapidly. How aware are patients of the causes of and cures for their diseases, and how well are they served by the healthcare providers in their countries?
- An estimated 33 million people are living with HIV globally, with 2.7 million new infections in 2007, mostly in sub-Saharan Africa. By 2007, only 3 million people had access to antiretroviral (ARV) therapy, while 6.7 million were in immediate need of treatment.
- There is recognition that ARV therapy may play a role in HIV prevention through post-exposure prophylaxis, pre-exposure prophylaxis, and treatment of HIV-positive individuals. However, WHO does not currently have a specific policy on using ARV therapy for prevention due to many unanswered questions.
- WHO will convene a meeting of stakeholders in May 2009 to discuss the feasibility,
Assessment of the level of awareness on AIDS/HIV in Johor, MalaysiaSriramNagarajan17
This document summarizes a study that assessed awareness of HIV/AIDS among 396 respondents in Johor, Malaysia. The study found that respondents had moderately high overall knowledge of HIV/AIDS, though some misconceptions remained. Most respondents knew that high-risk behaviors like needle sharing and unprotected sex can transmit HIV, but fewer were aware of risks from activities like tattooing or sharing personal items. While most knew there is no cure for HIV/AIDS, over half believed incorrectly that washing after sex prevents transmission. The study provides insight into awareness levels and information gaps regarding HIV/AIDS in Johor.
1. HIV remains a major public health problem, infecting 1.8 million people per year globally. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy, using antiretroviral drugs like Truvada to significantly reduce transmission risk.
2. While PrEP is highly effective at preventing HIV, it also increases the risk of other sexually transmitted infections. PrEP also faces stigma and the perception that it promotes reckless behavior.
3. Overall, PrEP is a markedly effective HIV prevention strategy that avoids unnecessary morbidity and mortality, though it comes with some adverse effects and challenges. Future PrEP methods may provide more convenient dosing options to improve safety, adherence and uptake.
Overview of the national Methadone Maintenance Treatment (MMT) program in Vie...Geraldine Cazorla
This document provides an overview of Vietnam's national Methadone Maintenance Treatment (MMT) program, including a discussion of its implementation process, key issues, and opportunities for scaling up. The author conducted surveys of key stakeholders and MMT clients/injecting drug users to analyze the program across four domains: legal framework, stakeholder responsibilities, financing, and technical factors. Key findings include contradictory responsibilities among government agencies, limited MMT supply and training capacity, challenges securing sustainable funding, and inconsistencies in legal frameworks. The author recommends clarifying roles, increasing resources, diversifying funding sources, and revising policies to address these issues and improve the national MMT program in Vietnam.
This document is a cover page and abstract for a culminating experience paper by Lindsey Garrison at Boston University School of Public Health. The paper analyzes adherence to antiretroviral therapy (ART) among adolescents in South Africa. It examines determinants of poor adherence, reviews best practices to improve adherence, and analyzes the ST-AMP program from the US. The paper identifies gaps in research and makes recommendations to improve data collection and gender-stratified statistics on HIV among adolescents in South Africa.

AIDSTAR-One Report: Rapid Assessment of Pediatric HIV Treatment in NigeriaAIDSTAROne
This document summarizes a rapid assessment of pediatric HIV treatment in Nigeria conducted by AIDSTAR-One in 2011.
Part I identified several barriers to providing quality pediatric HIV care: human resource constraints, lack of caregiver involvement, limited disclosure to children and adolescents, adherence challenges, and inadequate resources at sites. It provides recommendations to address these barriers, such as limiting staff transfers, improving caregiver support, using age-appropriate adherence tools, and expanding electronic medical records.
Part II reviewed outcomes of 1,516 pediatric patients and found 4.2% mortality and 19.1% loss to follow up. Few health systems challenges significantly impacted treatment outcomes. Earlier treatment initiation and reduced loss to follow up are needed.

Prompted by a growing knowledge of the complexity of HIV transmission, many countries are reassessing the nature of their HIV epidemics. "Mixed" epidemics, or concurrent epidemics experienced by both the general population and members of most-at-risk populations (MARPs), are of growing importance in HIV programming. Nigeria, a country with a range of regional and local epidemics, is now attempting to incorporate programming for MARPs into the national HIV response. This case study documents the country's analysis of its epidemics and the efforts of the Nigerian government to adjust their national strategic plan according to the results of the analysis.

TABLE 1. WORLD HEALTH ORGANIZATION RAPID ADVICE KEY RECOMMENDATIONS
Key Recommendations
1. Start antiretroviral therapy (ART) in all patients with HIV who have a CD4 count of less than 350 cells/mm3, irrespec-
tive of clinical symptoms.
2. Start one of the following regimens in ART-naïve individuals eligible for treatment.
• Zidovudine (AZT) + lamivudine (3TC) + efavirenz (EFV)
• AZT + 3TC + nevirapine (NVP)
• Tenofovir (TDF) + 3TC or emtricitabine (FTC) + EFV
• TDF + 3TC or FTC + NVP
3. Start ART in all individuals living with HIV with active tuberculosis, irrespective of CD4 cell count.
4. Start ART in all individuals living with both HIV and hepatitis B virus who require treatment for their hepatitis B virus
infection, irrespective of CD4 cell count or WHO clinical stage.
5. Start ART in all pregnant women with HIV and a CD4 count of less than 350 cells/mm3, irrespective of clinical symp-
toms.
6. Where available, use viral load (VL) to confirm treatment failure.
• Where routinely available, use VL every six months to detect viral replication.
• A persistent VL above 5,000 copies/mL confirms treatment failure.
• When VL is not available, use immunological criteria to confirm clinical failure.
7. A boosted protease inhibitor (bPI/r) plus two nucleoside analogues are recommended for second-line ART.
• For second-line ART, atazanavir/ritonavir (ATV/r) and lopinavir/ritonavir (LPV/r) are preferred.
8. National programs should develop policies for third-line therapy that consider funding, sustainability, and equitable ac-
cess to ART.

21. TABLE 9. SUMMARY OF IN-COUNTRY CHALLENGES WITH GUIDELINE IMPLEMENTATION
Country Challenge Description
Zambia Stavudine (d4T) Phased implementation of more patient-friendly regimens over a four-year
withdrawal period as a result of increased up-front costs.
Laboratory capacity Limited use of viral load (VL) for confirmation of treatment failure due to
prohibitive cost and weak laboratory capacity.
Laboratory capacity Limited implementation of recommendation for ART in all patients co-infected
with HIV/hepatitis B virus (HBV) due to weak laboratory capacity, increased
costs of HBV testing supplies, and increased antiretroviral therapy (ART) patient
loads.
ART for patients with Recommends starting ART in all active TB patients within two to four weeks
tuberculosis (TB) after starting TB treatment to manage decision point about “when to start.”
Second-line therapy High cost of second-line; plans for gradual transition from lopinavir/ritonavir
(LPV/r) to atazanavir/ritonavir (ATV/r) due to expected cost savings.
Third-line therapy Developed draft third-line guidelines that recommend raltegravir (RAL) and
darunavir/ritonavir (DRV/r); established third-line advanced treatment center.
Guyana Supply chain Delayed implementation of more patient-friendly regimens resulting from an
management overstock of old antiretrovirals (ARVs).
South Africa Supply chain Delayed implementation of more patient-friendly regimens resulting from lack of
management advance planning with ARV suppliers.
d4T withdrawal Health care workers switching patients to tenofovir (TDF) who do not meet
eligibility criteria, adversely impacting national TDF stocks.
Nicaragua Supply chain Delayed implementation of earlier ART initiation due to stockouts of CD4
management reagents and problems with VL testing equipment.
Cambodia d4T withdrawal Exclusion of more patient-friendly regimens from revised guidelines due to
prohibitive up-front costs.
Laboratory capacity Plans for VL scale-up hampered by prohibitive cost.
Laboratory capacity Exclusion of recommendation for ART in all patients co-infected with HIV/HBV
from revised guidelines due to prohibitive cost and limited availability of HBV
serodiagnostic and virologic tests.
ART for TB patients Recommends starting ART in all active TB patients within two weeks of TB
treatment to manage decision point around “when to start.”
Zimbabwe d4T withdrawal Phased implementation of more patient-friendly regimens over a three-year
period as a result of increased up-front costs.
Tanzania d4T withdrawal Phased implementation of more patient-friendly regimens over a three-year
period as a result of increased up-front costs; health care workers switching
patients to TDF who do not meet eligibility criteria adversely impacting national
TDF stocks.
Honduras Laboratory capacity Delayed implementation of earlier ART initiation due to unavailability of CD4
testing at the primary care level.
Laboratory capacity Limited use of VL for confirmation of treatment failure due to four- to eight-
month turnaround time for VL test results.
ART for TB patients Administer empirical TB treatment to suspected TB patients and monitor for
clinical improvement to manage difficulty with accurate diagnosis of TB.
Third-line therapy New HIV strategy includes plans to offer third-line therapy through the public
sector at third- and fourth-level health centers.
