Dengue's spread

Dengue is an outbreak-prone, unpredictable disease with a first infection raising the risks that subsequent infections may become severe.

It's transmitted by mosquitoes, so multiple factors, including urbanization, water storage practices and vector control measures can impact the risk for dengue-endemic communities.3

Protecting people at risk

In 2015, we introduced the first dengue vaccine which is registered in several endemic countries, contributing a medical intervention into the ongoing integrated global public health effort to manage and control the disease.
