Düsseldorf / Stuttgart - Yellow fever vaccinations no longer have to be refreshed every ten years from now on. This was decided by the World Health Organization () and the International Health Regulations changed accordingly. Accordingly, when entering WHO member states, proof of single vaccination will in future be sufficient.
"Despite the binding guidelines of the WHO, we will have to wait and see whether these will actually be implemented at all borders promptly," said Tomas Jelinek , Scientific Director of the Center for Travel Medicine. In light of the ongoing and new outbreaks of yellow fever, some countries in Africa and Central and South America and Asia are currently tightening their controls. Before traveling to country where yellow fever occurs or yellow fever vaccination is compulsory, travelers should inform themselves precisely about the implementation and handling of the controls at the respective borders.
Yellow fever is transmitted by daytime and nocturnal mosquitoes. The infection starts suddenly with high fever and general symptoms. Usually the disease heals afterwards. However, it can also worsen dramatically with jaundice and bleeding followed by heart, circulatory, liver and kidney failure. These complications often lead to death. Yellow fever is subject to strict international reporting requirement.
