NEWS How is climate change affecting the spread of mosquito-borne viruses? Could diseases such as dengue fever and West Nile virus become more common in Europe? These questions are at the heart of a course at ͯÑÕÊÓƵ, 8–12 June, where international researchers and doctoral students will explore how mosquito-borne diseases spread and how they can be prevented.

This makes the field particularly urgent,” says Olivia Wesula Lwande, researcher at the Department of Clinical Microbiology at Umeå University and course coordinator.
Mosquitoes are major vectors of viruses, bacteria and parasites that can cause disease in both humans and animals. While tropical mosquito-borne diseases remain rare in Sweden, climate change and increased global mobility have made the issue more pressing. In recent years, viruses such as West Nile virus have caused outbreaks in several European countries, and researchers are closely monitoring how both viruses and mosquito species are shifting their geographical ranges.
“Research on zoonotic viruses in mosquitoes is crucial, as it helps detect and prevent future disease outbreaks,” says Olivia Wesula Lwande.
The course combines lectures with hands-on training in both field and laboratory settings. Participants will learn how to identify mosquito species, collect mosquitoes in the field, and apply modern methods for pathogen surveillance and analysis. The course also highlights the importance of cross-disciplinary collaboration, spanning biology, medicine, public health and environmental science.

NDP-VIP aims to strengthen education and recruitment of doctoral students and postdoctoral researchers in virology and pandemic preparedness. The programme is a collaboration between nine Swedish universities and is coordinated from Umeå University, where it is affiliated with the Umeå Centre for Microbial Research (UCMR).
