- How is the West Nile virus transmitted?
- The virus is primarily transmitted between wild birds and Culex mosquitoes, which then can transmit it to humans and other mammals. The RKI notes that increased testing of blood donors has contributed to higher reported case numbers in recent years.
- Why is there a high number of unreported cases?
- The RKI emphasizes a significant underreporting of West Nile virus infections due to the high percentage of asymptomatic cases. This makes it difficult to ascertain the true extent of the outbreak.
- What are the common symptoms of West Nile virus infection?
- The majority of West Nile virus infections are asymptomatic (80%), while around 20% show mild symptoms like fever or rash. Severe cases, which can be fatal, mostly affect older people with pre-existing conditions.
- What is the trend of West Nile virus cases in Germany in recent years?
- The RKI has reported increased numbers of West Nile Virus cases since 2019, primarily in eastern Germany. Experts anticipate that climate change will further increase cases.
- How many people in Germany have been infected with the West Nile virus this year?
- At least 26 people in Germany have been infected with the West Nile virus this year, with the Robert Koch Institute (RKI) stating that the reported cases are only a fraction of the actual number. Most cases were found in Saxony, Saxony-Anhalt, and Berlin.
