Dengue fever

Last updated: 28 May 2015

Dengue fever is a growing problem.

Do you know if your people are at risk?

Dengue is a common viral infection spread by mosquitoes. After infection, most people are able to recover, in some cases however it can be severe – even fatal. There is no medication or vaccine against it, although preventing mosquito bites prevents infection.

There are an estimated 100 million cases of dengue fever each year with an increasing number of international travellers being infected. As businesses continue to expand leading to the urbanisation of previous rural areas, dengue has become a risk for employees working in tropical climates.
