Dengue virus. Dengue virus (DENV) is the cause of dengue fever. It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Five serotypes of the virus have been found, all of which can cause the full spectrum of disease.
Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash. Recovery generally takes two to seven days.
2017. A Dengue fever outbreak in the Indian state of Kerala in May and June 2017 had caused 6808 confirmed infections and 13 deaths by June 16. In Sri Lanka, there were 180,000 reported cases in 2017. The majority of cases being reported from the Western province.
The 2017 dengue vaccine controversy in the Philippines involved a vaccination program run by the Philippines Department of Health. It vaccinated schoolchildren with Sanofi Pasteur's CYD-TDV (Dengvaxia) dengue vaccine. Some of the children who received the vaccine had never been infected by the dengue virus before.
The 2017 Uganda Marburg virus outbreak was confirmed by the World Health Organization (WHO) on 20 October 2017 after there had been an initial fatality due to the virus.. The Ugandan Ministry of Health indicated that an individual had died of the virus on 19 October; the following day, 20 October, WHO released a press statement regarding the matter.
Influenza, commonly known as "the flu", is an infectious disease caused by an influenza virus. Symptoms can be mild to severe. The most common symptoms include: high fever, runny nose, sore throat, muscle and joint pain, headache, coughing, and feeling tired.
The full life cycle of dengue fever virus involves the role of mosquito as a transmitter (or vector) and humans as the main victim and source of infection. The virus The dengue virus (DEN) comprises four distinct serotypes (DEN-1, DEN-2, DEN-3 and DEN-4) which belong to the genus Flavivirus, family Flaviviridae.
Mar 02, 2020 · In 2017, a significant reduction was reported in the number of dengue cases in the Americas - from 2 177 171 cases in 2016 to 584 263 cases in 2017. This represents a reduction of 73%. Panama, Peru and Aruba were the only countries that registered an increase in cases during 2017.
Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. Dengue is common in more than 100 countries around the world. Forty percent of the world’s population, about 3 billion people, live in areas with a risk of dengue.
