The incidence of dengue fever, the mosquito borne viral disease, has grown dramatically around the world in recent decades, according to the World Health Organization (WHO).
Over 2.5 billion people – over 40% of the world’s population – are now at risk from dengue. WHO currently estimates there may be 50–100 million dengue infections worldwide every year.
The disease is now endemic in more than 100 countries in Africa, the Americas, the Eastern Mediterranean, South-east Asia and the Western Pacific. South-east Asia and the Western Pacific regions are the most seriously affected.
Here are updates on the situations on several Asian countries in 2015:
