Museum scientists study a range of diseases particularly tropical ones, from well-known viruses, such as Dengue and yellow fever, through to lesser known parasites like the common liver fluke. They also examine the organisms that host dangerous parasites before they are passed on to humans.

By learning more about how diseases spread and enter the human body, we may be able to diagnose and treat them more effectively in the future. Explore the species that help Museum scientists to study tropical diseases below.
