Track dengue

Dengue can affect millions of people around the world every year and cases are increasing dramatically.1

Population growth, urbanization, increased travel, climate change, and failing control measures can all cause the dengue virus to spread.2

Before 1970 only nine countries had experienced a dengue epidemic. Now dengue is found in more than 100 countries worldwide.1

Dengue is constantly shifting and changing.

Scientists can track dengue by testing people’s blood for antibodies

These special proteins can show whether a person has had dengue and if they may be at risk of severe dengue.3


By developing technologies that can test for dengue in more remote areas, scientists can build a more accurate picture of where dengue is spreading and which version of the virus may be causing it.4

Even internet searches can help! Scientists have found a link between a spike in dengue-related internet searches and actual cases. This is helping to track dengue in less-developed countries.5

In Pakistan, local government staff use a mobile app to report areas of mosquito activity and breeding. They combine this with confirmed cases of dengue in hospitals to predict where an outbreak might occur.6,7

And scientists in the US are using a combination of medical data, internet search data, social media mentions, and recorded test results to build a huge model of the disease to predict future cases.8
