Yellow fever vaccination is the most important and effective preventive measure. The vaccination is a live vaccination, which means that it is contraindicated during pregnancy and immunosuppression, i.e., must not be used. In order to prevent yellow fever, it is also necessary to reduce the risk factors.
Behavioral risk factors
- Poor protection from mosquitoes in endemic areas of Africa and South America. Transmission of the pathogen (route of infection) occurs via mosquitoes of the genera Aedes and Haemagogus. The former are diurnal and nocturnal. In exceptional cases, transmission through blood donations is possible.
