- Why are there more reported cases in recent years?
- The increase in reported cases in recent years is partially attributed to more extensive blood donor testing. In the past, testing wasn't as comprehensive, leading to a higher number of undetected infections.
- How is the West Nile virus transmitted, and what are the main hosts?
- The West Nile virus is transmitted by blood-sucking mosquitoes, primarily Culex mosquitoes. Birds serve as the main hosts, and infected mosquitoes can transmit the virus to humans and other mammals.
- 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 majority of cases reported in Saxony, Saxony-Anhalt, and Berlin. The infections were primarily transmitted through the bites of local mosquitos.
- How many of the West Nile virus infections were detected in asymptomatic blood donors?
- The Robert Koch Institute (RKI) reports that 13 of the 26 infections were detected in blood donors who showed no symptoms. Four of the infected individuals developed severe illness.
- What percentage of West Nile virus infections are asymptomatic, and what are the common symptoms of symptomatic cases?
- Approximately 80% of West Nile virus infections are asymptomatic, while around 20% result in mild, unspecific symptoms such as fever or rash. Severe cases, often affecting older people with pre-existing conditions, are rare, affecting only about 1% of those infected.
