We all dread the mention of dengue. It is a viral infection caused by the bite of an infected mosquito. It is only the Aedes type of mosquitoes that transmits the virus, and only a fraction of the mosquitoes are infected. The infection causes flu-like symptoms such as high fever, headaches typically behind the eyes, muscle and joint pain, nausea and stomach ache.
The number of dengue cases globally is on the rise. About 390 million people are infected by dengue every year worldwide. But of these, only 25% – or 100 million – may develop symptoms according to the World Health Organisation.
According to a study conducted by Dr Katja Fink of A*STAR with blood samples from healthy student volunteers from the National University of Singapore, about 80% who have been infected by dengue based on their antibody titers did say that they never had a dengue infection when asked .
