The document summarizes the status of pre-exposure prophylaxis (PrEP) implementation in Europe based on data from 2018-2019. It finds that while formal PrEP rollout has been slow, especially in Eastern Europe and Central Asia, there is evidence of significant informal PrEP use across countries. As a result, an estimated 500,000 men who have sex with men (MSM) want or need PrEP but are unable to access it, representing a "PrEP gap" in Europe. Barriers to wider PrEP implementation include cost and lack of public funding in some countries.
- There were 49,752 TB cases notified in 29 EU/EEA countries in 2019, with a notification rate of 9.6 per 100,000 population. The number and rate of TB cases have declined steadily between 2010-2019.
- Males had higher notification rates than females across all age groups over 14. The highest rate was in those aged 25-44.
- 34.5% of cases were in persons of foreign origin, up from 25.3% in 2010.
- Treatment success rates after 12 months of treatment declined from 76.2% in 2009 to 63.7% in 2018.

This document summarizes a presentation given by Anastasia Pharris of the European Centre for Disease Prevention and Control on infections among people who inject drugs. It finds that over 30,000 new HIV diagnoses in Europe in 2016 were due to injecting drug use, with most cases concentrated in Eastern Europe. While harm reduction efforts have made progress in some countries, people who inject drugs still face high burdens of HIV, hepatitis C, and other infections. The presentation calls for improved testing, treatment, and prevention programs targeting this group.

1) Hepatitis E virus (HEV) infection has emerged as an important public health issue in Europe, with over 21,000 cases reported between 2005-2015 across EU/EEA countries.
2) Surveillance systems and case definitions for HEV vary between countries, but most (20/30) now have specific national surveillance for HEV in place.
3) The majority (98%) of HEV cases in Europe are now locally acquired rather than travel-associated, and over half of all cases are diagnosed in hospitals.

This document summarizes measles and rubella surveillance trends in Europe from 2013-2016 based on data reported to the European Centre for Disease Prevention and Control. It finds that while measles cases decreased between 2008-2011, they have since increased, with over 3700 cases reported in EU/EEA countries in 2016. The majority of measles cases were either unvaccinated or had an inadequate vaccination status. Rubella cases have remained low and stable during this period, with 1307 total cases reported in EU/EEA countries in 2016.
1) 58,994 TB cases were notified in 30 EU/EEA countries in 2016, with a notification rate of 11.4 per 100,000 population. The number and rate of TB cases have declined continuously between 2007-2016.
2) The highest notification rates in 2016 were among those aged 25-44, and males had higher rates than females in all groups over 14. Rates have declined annually by 2-4% in all age groups between 2007-2016.
3) 32.7% of cases in 2016 were in persons of foreign origin, an increase from 21% in 2007. The rate of cases in foreign-born persons was stable between 2007-2016.

This document analyzes EU surveillance data from 2009-2014 on shigellosis, a bacterial infection transmitted through contaminated food or water or directly from person to person through feces. The analysis found that domestically-acquired shigellosis cases increased over this period and accounted for over half of reported cases in 2014, with the proportion of cases among men doubling. Male-to-female ratios were highest among domestic cases, suggesting ongoing sexual transmission of certain Shigella strains like S. flexneri serotype 3a among men who have sex with men in Europe. The authors conclude countries should investigate domestic male cases and sexual transmission more and report such data to help monitor trends and facilitate public health interventions.

- The number of TB cases in the EU/EEA decreased by 30% from 2006 to 2015 while the notification rate decreased by 37% over this period.
- The highest notification rate in 2015 was observed in the 25-44 year old age group. Males had higher notification rates than females in most age groups.
- Treatment success rates for TB cases remained stable around 72-75% from 2005-2014. The treatment success rate for MDR TB cases was lower at 40.4%.

Although HIV is preventable through effective public health measures, significant HIV transmission continues in Europe. In 2015, almost 30 000 people were diagnosed in European Union and European Economic Area Member States; a rate of 6.3 cases in every 100 000 people (when adjusted for reporting delay).
This report, prepared jointly with the WHO Regional Office for Europe, presents data on HIV and AIDS for the whole European Region, including the EU and EEA countries. Analyses are provided for the EU and EEA region.
The document discusses HIV infection among children and adolescents in the European Union and European Economic Area (EU/EEA). It provides statistics on new HIV diagnoses from 2006-2015, showing an increase among adolescents ages 15-19. The majority of infections in children under 15 were due to mother-to-child transmission, while most adolescents were infected through heterosexual sex or sex between men. While mother-to-child transmission rates are declining in EU/EEA-born children, transmission remains high in children born outside the EU/EEA to migrant mothers. The document calls for targeted HIV prevention strategies focusing on at-risk groups.
Based on ECDC surveillance report on Sexually transmitted infections in Europe 2013, these slides describes the epidemiological features and basic trends of the five STI under EU surveillance: chlamydia trachomatis infection, gonorrhoea, syphilis, congenital syphilis, and lymphogranuloma venereum. It covers the years 2004 to 2013.
Although HIV is preventable through effective public health measures, significant HIV transmission continues in Europe. In 2014, almost 30 000 people were diagnosed in European Union and European Economic Area Member States.

The document summarizes HIV/AIDS surveillance data in Europe for 2017. Some key findings are:
- 25,353 new HIV diagnoses were reported in 30 EU/EEA countries in 2017.
- Sex between men accounted for 38% of new diagnoses, while heterosexual transmission accounted for 33%.
- Nearly half (49%) of individuals were diagnosed late, with a CD4 count below 350 cells/mm3.
- Migrants accounted for 41% of new diagnoses, many originating from sub-Saharan Africa and Latin America.

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 provides data and statistics on HIV/AIDS in the Philippines from 1990-2021. It summarizes estimated numbers of people living with HIV, new HIV infections, AIDS-related deaths, and people receiving antiretroviral therapy (ART) over time. Key facts presented include HIV prevalence among key populations like sex workers, men who have sex with men, and transgender people. Statistics on domestic and international AIDS spending by category and financing source are also shown.
HCV Treatment Access across Europe - Raquel PeckReShape
The document discusses hepatitis C virus (HCV) treatment access across Europe. It notes that the World Health Organization and Global Hepatitis Summit have set goals to eliminate viral hepatitis by 2030. The document then provides statistics on HCV prevalence and treatment rates across the European Union, with over 3.6 million estimated viremic infections but only 133,000 patients treated in 2015. Case studies are presented on HCV elimination efforts in countries like France, Germany, Portugal, and Australia. The document argues for more active screening, prevention efforts, expanding treatment eligibility criteria, and ensuring strong patient advocacy to work towards HCV elimination in the EU.

The document discusses HIV treatment cascades which show the proportion of people living with HIV who are diagnosed, treated, and virally suppressed. It provides examples of cascades for HIV care in the UK and US in 2014-2015. The UNAIDS 90-90-90 targets aim to have by 2020, 90% of people with HIV diagnosed, 90% of those diagnosed on antiretroviral therapy, and 90% of those treated virally suppressed. The document notes current global estimates are far from these targets and outlines the gaps that need to be addressed to meet them by 2020 in order to end the AIDS epidemic. It also discusses the World Health Organization's goal of ending AIDS as a public health threat by 2030
Dr. Kathleen Brady (AACO)'s annual epidemiological update. This presentation was given to the Philadelphia EMA Ryan White Planning Council on Thursday, February 20, 2014.
The document discusses metrics for monitoring the cascade of HIV services across the continuum of care. It presents a conceptual framework showing the cascade from diagnosis to viral suppression. Key metrics are identified to measure progress at each stage, including the percentage of people living with HIV who know their status, are linked to care, initiated on antiretroviral therapy, and have achieved viral suppression. The metrics were field tested in two countries and found useful for program assessment. Challenges include data quality and capacity at the local level. Guidelines will be published in early 2014 to help countries use these metrics to identify gaps and improve program performance.
Kathleen Brady from the Philadelphia Department of Public Health presented her annual updated on the HIV Epidemic in Philadelphia at a February 2015 combined meeting of the Philadelphia Ryan White Part A Planning Council and the HIV Prevention Planning Group.
This document summarizes tuberculosis monitoring indicators for the WHO European Region in 2016. It analyzes 19 indicators across three areas of intervention: integrated patient-centered care and prevention, bold policies and supportive systems, and intensified research and innovation. For most indicators, only a small number of countries met the targets, suggesting more progress is still needed to tackle TB across the European Region.
Where are we on HIV testing services - the achievements and the gapsCheryl Johnson
This document discusses achievements and gaps in HIV testing services globally. It finds that approximately 17 million people with HIV still do not know their status, and linkage to treatment after testing is suboptimal. While over 150 million people received HIV testing in 2014, nearly half of all people with HIV remain undiagnosed globally, with lower testing rates among men, adolescents, and key populations. The document calls for new approaches to testing like self-testing and lay providers, as well as improving quality, coverage, and focus on missing populations and areas with ongoing high risk.
What is epidemic control after 2020 mwango 04082021Albert Mwango
This document discusses epidemic control in the context of HIV/AIDS. It defines epidemic control as reaching a point where new HIV infections fall below deaths from all causes in infected individuals. It outlines global 90-90-90 goals to achieve epidemic control by having 90% of infected people know their status, 90% on antiretroviral therapy, and 90% virally suppressed. While some countries like Zambia have met 90-90-90 targets, new global infections remain off target for epidemic control due to declining rates of status awareness, treatment coverage, and viral suppression in recent years.
This document discusses Zika virus and provides information for clinicians. It describes the epidemiology of Zika virus, including transmission and outbreaks in the Americas. It outlines the clinical presentation of Zika virus disease and discusses diagnostic testing. It also addresses maternal-fetal transmission of Zika virus and the relationship between Zika virus infection during pregnancy and microcephaly in infants.
Similar to Strategies to reduce HIV incidence in Europe (20)
This document summarizes a presentation on estimating mortality due to viral hepatitis using attributable fractions. It discusses:
1) The WHO reference method which uses national mortality statistics and attributable fraction estimates from GBD to estimate hepatitis-related deaths.
2) A sentinel pilot study conducted in Bulgaria and Portugal to develop local estimates of the attributable fractions of cirrhosis and liver cancer caused by hepatitis B and C. The pilot found the attributable fractions varied between sites.
3) Outcomes from the pilot included improved local mortality estimates and lessons learned for expanding the methodology to other countries through clinical and public health partnerships. Limitations around representing overall populations and assigning morbidity to mortality were also noted.
Respondent Driven Sampling (RDS) is a technique for sampling hard-to-reach populations. It works by having initial participants (seeds) recruit a small number of people from their social networks, who are then eligible to recruit others from their networks. This process continues in successive waves. RDS relies on assumptions about network structure and recruitment behaviors. Analysis adjusts for network size and recruitment patterns. The technique was used to sample migrants in Morocco to estimate HIV, syphilis, and tuberculosis prevalence and understand their demographics, risks, and access to services. Results provided insights to guide health programs for this population.

Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
The skin is the largest organ and its health plays a vital role among the other sense organs. The skin concerns like acne breakout, psoriasis, or anything similar along the lines, finding a qualified and experienced dermatologist becomes paramount.

Editor's Notes
430 000 undiagnosed
620 000 diagnosed and not on treatment
150 000 on treatment but not supressed
1.2 million individuals living with unsupressed HIV
1.2 million individuals living with unsupressed HIV
1.2 million individuals living with unsupressed HIV
Individual as well as public health benefits of early diagnosis
Even in best performing countries ¼ of cases are diagnosed late, however for most half or even more are diagnosed late.
AIDS defining illnesses, conditions where prevalence of HIV found to be >0.1%, and conditions where not testing would harm patient health.
The aim of the Swab2know project was to detect new HIV cases among MSM in Belgium – a group at high risk for HIV. Before outreach activities, a secure and encrypted website was designed specifically for the project, with the aim of providing a platform where visitors could find information and prevention messages, order test kits and collect test results. The oral fluid samples in the kits were self-collected by the participants under the remote supervision of study staff.
Within the project, the number of MSM tested for HIV was 898; 17.1% reported they had never been tested for HIV before. Among those tested, the positivity rate was 2.2%. All new cases were successfully linked to HIV care. Despite a high yield and a considerable number of false reactive results, satisfaction was high among participants.
To sustain the intervention, the Swab2Know team concluded that an emphasis on Internet-based testing and repeated testing for participants would be needed, as well as strong collaboration with community-based and prevention organizations to guide MSM to the project. Additionally, the online counselling tool should be refined to support participants, with an increased emphasis on those with a reactive result, and there should be increased efforts to reduce the number of false reactive tests and expand the types of tests offered to STIs. Another priority was to develop the legal framework for self-testing and self-sampling, as neither are officially recognised in Belgium.
Based on the inclusion of 7 interventions in public health programmes; these are most effective if delivered in combination.
may depend on local factors, including organizational and legal circumstances, there is limited evidence that educational interventions targeting healthcare workers may prove to be beneficial.
