This document summarizes information about dengue, a mosquito-borne viral infection. It discusses the global incidence and distribution of dengue, noting that incidence has increased in recent decades. Dengue symptoms and the different forms it can take are described. Treatment involves symptom relief and fluid maintenance. Vaccines have been developed but have limitations. Prevention relies on controlling mosquito populations and limiting their habitats. Global and national strategies aim to reduce dengue burden through prevention, control programs, and surveillance.
Dengue (pronounced DENG-gay) can affect anyone but tends to be more severe in people with compromised immune systems. Because it is caused by one of four serotypes of virus, it is possible to get dengue fever multiple times. However, an attack of dengue produces immunity for a lifetime to that particular serotype to which the patient was exposed.

An overview on Dengue Virus, its epidemiology, prevention, evolution, structure & components, transmission, life cycle, pathophysiology, coagulopathy, symptoms, diagnosis, antiviral drugs/vaccination. Performed by Catherine Duong, Diana Elborno, Zehraa Cheaib, Michael South, Veronica Nguyen & Zachary Jilesen at McMaster University, Virology, Fall of 2014.
Monkeypox is a zoonotic disease endemic in the Democratic Republic of Congo (DRC) but prevalent also in other countries of Central and Western Africa. The clinical presentation of monkeypox closely resembles the one of smallpox. The mortality rate is officially about 11% however rates as high as 17% have been observed. The disease has been considered rare and not much attention is paid to it. Nonetheless, the incidence of monkeypox increased 20-fold from 1981-1986 to 2005-2007 (two active surveillance programs). More research, surveillance and effective interventions are needed to ensure it would not gain the potential to become the next global pandemic.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. INTRODUCTION
• Dengue is a mosquito born viral infection which causes flu like illness,and
occasionally develops into a potentially lethal complications.
• It is transmitted by the infective bite of female Aedes Aegypti mosquito
•Man develops disease after 5-6 days of being bitten by an infective
mosquito.
•It occurs in two forms: Dengue Fever and Dengue Haemorrhagic
Fever(DHF called severe dengue.)
3. Incedence:390 million
dengue infections per
year of which 96 million
manifest clinically
Prevalence:3.9 billion
people in 128 countries
No. of cases reported
increased from 2.2
million in 2010 to 3.2
million in 2015.
Global burden of
Dengue
4. DISTRIBUTION TRENDS
• Before 1970- only 9 countries experienced severe dengue epidemics.
• Now :endemic in more than 100 countries in WHO regions of Africa, the
Americas, the Eastern Mediterranean, South-East Asia and Western Pacific.
• 2010:local transmission of disease was reported for the first time in France
and Croatia
• 2012:an outbreak of dengue on the Maderia island of Portugal in over 2000
case and imported cases were detected in mainland Portugal and 10 other
countries in Europe
• 2014:trend indicates increase in number of cases in the People’s Republic
of China,the Cook Islands,Fiji,Malaysia and Vanuata, with Dengue Type
3(DEN 3) affecting the Pacific Island countries after a lapse of over 10 yrs .
Also reported in Japan after a lapse of 70 years.
5. Continue.....
• 2015: Delhi,India, recorded its worst outbreak since 2006 with over
15000 cases.The Island of Hawaii, United States of America was
affected by an outbreak with 181 cases and ongoing transmission in
2016. The Pacific island countries of Fiji, Tonga and French Polynesia
have continued to record cases.
• 2016: large outbreaks worldwide; the American regions:2.38 million
cases, Brazil:>1.5 million cases,1032 dengue deaths,The Wesrern
Pacific Region<375000 cases, of which Phillipines:176411 cases and
Malaysia:100 028 cases,The Solomon Island: outbreak of 7000
suspected cases,the African region,Burkina Faso:outbreak of 1061
cases
6. Continue....
• 2017:significant reduction in number of cases in tge Americas-from
2177 171 cases in 2016 to 584 263 cases in 2017 i.e. 73% reduction,
Panama,Peru and Aruba showed increase in number of cases;53%
reduction in severe dengue this year
• 2018:In the first quarter of the year a reduction of 27% of
cases,Paraguay and Argentina ,reported outbreak,cases were also
reported from
Bangladesh,Cambodia,India,Myanmar,Malaysia,Pakistan,Philippines,T
hailand, and Yemen
7. Continue...
• An estimated 500 000 people with severe dengue require
hospitalization each year, and 2.5% case fatality annually
• Globally 28% decline in case fatality between 2010 and 2016 with
significant improvement.
8. In context of Nepal
• The earliest cases was detected in 2005,sporadic cases and outbreaks
in 2006 and 2010.
• Indigenous cases are also being reported
• Chitwan, Kanchanpur, Kailali, Baken, Bardiya, Dang,Kaoilvastu, Parsa,
Rupendehi,Rautahat, Sarlahi, Saptari and Jhapa districts of Nepal
reflect the spread of the disease throughout the Terai plains from
west to east
• In 2011 79 confirmed cases were reported from 15 districts with
highest number in Chitwan(55).
9.
10. Treatment
No specific treatment for dengue fever
Symptomatic treatment
Maintenance of patient’s body fluid volume is critical to severe
dengue care.
11. Immunization
• The first dengue vaccine ,Dengvaxia(CYD-TDV) developed by Sanofi
Pasteur was licensed in December 2015.
• Approved by regulatory authorities in 20 countries for use in endemic
areas in person ranging from 9-45 years of age as clinical trial.
• In April 2016,WHO issued a conditional reccomendation on the use of
the vaccine for areas in which dengue is highly endemic.
• The live attenuated vaccine is safe and efficacious in person who have
had a previous dengue virus infection but carries an increased risk of
severe dengue in those experiencing their first natural dengue
infection.
12. Prevention and Control
• At present the main method to control or prevent the transmission of
dengue vrus is to combat through:
• Preventing mosquitoes from accessing egg lying habitats by environmental
management and modification;
• Disposing of solid waste properly and removing artificial man made
habitats;
• Covering ,emptying and cleaning of domestic water storage containers on
a weekly basis;
• Applying appropriate insecticides to water storage outdoor containers;
• Using of personal househoid protection such as window screens,long
sleeved clothes, insecticides treated materials, coils and vaporizers;
13. Continue..
• Improving community participation and mobilization for sustained
vector control;
• Applying insecticides as space spraying during outbreaks as one of the
emergency vector-control measures;
• Active monitoring and survillence of vector should be carried out to
determine effectiveness of control interventions.
14. Global Strategy
For Dengue Prevention And Control
• Goal And Objectives
The goal of the global strategy is to reduce the burden of dengue.It’s
specific objectives are:
To reduce dengue mortality by at least 50% by 2020
To reduce dengue morbidity by at least 25% by 2020
To estimate the true burden of the disease by 2015
15.
16. Nepal’s Dengue Control Programme
• Goal-To reduce morbidity and mortality due to dengue fever,dengue
haemorrhagic fever and dengue shock syndrome.
• Objectives
• To develop an integrated vector management approach for
prevention and control.
• To develop capacity on diagnosis and case management of dengue
fever,DHF,DSS.
• To inensify health education and IEC activities.
• To strengthen the survillence system for predection,early detection,
preparedness early response to dengue outbreaks.
17. strategies
• Early case detection, diagnosis , management, and reporting of
dengue fever, DHF and DSS
• Regular monitoring of dengue fever, DHF and DSS cases and
survillence through EWARS.
• Mosquito vector survillance in municipalities.
• The integrated vector control approach where a combination of
several approaches are directed towards containment and source
reduction.
18. Major activities in 2073/74
• Trained physicians, nurses, paramedics and laboratory technicians on
dengue case detection, diagnosis, management, and reporting.
• Orientated municipality stakeholders in 25 programme districts.
• Supplied rapid diagnostic test kits(IgM).
• Dengue case monitoring and vector survillance.
• Search and destruction of dengue vector larvae (A. Aegypti) in 25
programme districts.
• Developed and disseminated health education messages.
19. Achivements
• A total of 1527 dengue cases were reported from 42 districts in
2073/74 . The most were from Chitwan (687) followed by Jhapa and
Rupendehi. And there was one confirmed deaths due to dengue in
Chitwan.
• The number of reported dengue cases has decreased significantly
since 2010 with high percent increase in the last three years from 302
to 134 to 1527 in the current year.the majority of cases have been
reported from Chitwan,Jhapa and Rupendehi with more than 46% of
2073/74 cases from Chitwan.
Incidence grown dramatically around the world
Actual numbers of the cases are under reported and many case are misclassified.
Although the full global burden of the disease is uncertain,the initiation of activities to record all dengue cases partly explains sharp increase in the no. Of cases reported in recent years.
Other features of the disease include its epidemilogical patterns including hyperendemicity of multiple dengue virus serotypes in many countries and the alarming impact on both human health and the global and national economics.
Dengue is one of the 17 neglected tropical diseses.
