However, there is some good news as the weather gets colder in Taiwan–a noticeable drop in dengue fever cases in recent weeks. After seeing 1,000-plus cases per week for weeks, a total of 763 new dengue fever cases were confirmed during the week Dec. 2-10.

The week prior Taiwan saw 885 cases.

The Taiwan CDC still advises the public to be vigilant to pay attention to indoor vector breeding sites during winter time.

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.

People get the dengue virus from the bite of an infected Aedes mosquito. It is not contagious from person to person. For more infectious disease news and informationvisit and “like” the Infectious Disease News Facebook page

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).

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