The national health agency reported there have 378 confirmed cases of dengue fever in Taiwan so far this year (as of July 25), compared with some 200 during the same period in 2013.

Seventy-three percent of the dengue cases (276) were considered locally-acquired, while the imported cases were reported from Indonesia, Malaysia, Thailand and Singapore.

Dengue fever is an infectious disease carried by mosquitoes and caused by any of four related dengue viruses. This disease used to be called “break-bone fever” because it sometimes causes severe joint and muscle pain that feels like bones are breaking.

The World Health Organization (WHO) estimates there may be 50–100 million dengue infections worldwide every year. However, new research fromthe University of Oxford and the Wellcome Trust, using cartographic approaches, estimate there to be 390 million dengue infections per year worldwide.

There are three types of dengue fever in order of less severe to most: the typical uncomplicated dengue fever, dengue hemorrhagic fever (DHS) and dengue shock syndrome (DSS).

There is not a vaccine for dengue fever. There is no treatment for dengue, just treat the symptoms.
