What is Dengue Fever

Jun 21, 2018

In many parts of the world, dengue fever is an emerging pandemic of viral disease. Dengue fever thrives in poor urban areas, suburban areas and rural areas, but it also affects more affluent communities in tropical and subtropical countries.

Dengue fever is a mosquito-borne viral infection that causes severe flu-like illness and sometimes causes potentially fatal complications called severe dengue fever. The incidence of dengue fever has increased 30-fold in the past 50 years. It is currently estimated that more than 500 million to 100 million infections occur each year in more than 100 endemic countries, placing almost half of the world’s population at risk.

Serious dengue fever(formerly known as dengue haemorrhagic fever) was first discovered during the dengue fever epidemic in the Philippines and Thailand in the 1950s. Today it affects Asian and Latin American countries and has become a major cause of hospitalization and death of children and adults in these areas.

The entire life cycle of the dengue virus involves the role of mosquitoes as communicators (or vectors) and humans as the primary victims and sources of infection.
