Following Brazil last year was Paraguay (223,082), Vietnam (121,398 during the first 11 months),  Mexico (120,239) and Malaysia with more than 88,000 cases.

According to ECDC, Dengue is a mosquito-borne viral disease widely spread in tropical and subtropical regions. The disease is transmitted by Aedes mosquitoes, which breed in the peridomestic environment. While most of the clinical cases present a febrile illness, severe forms including hemorrhagic fevers and shock with fatalities are reported.

There are 4 different dengue types, and infection with one type gives little immune protection against the other types. After an incubation of 8-10 days, a mild and usually self-limited flu-like illness develops. Current scientific evidence shows that sequential infection increases the risk of a severe form of the infection with bleedings – dengue hemorrhagic fever.
