West Nile Virus On The Rise In Germany

Researchers in Germany have been warning of an uptick in West Nile Virus (WNV) cases and 2020 looks to be no exception. In 2018, the disease, carried by mosquitoes, infected 12 birds and two horses; in 2019 there was a massive increase in cases, with confirmed cases in 76 birds, 36 horses and five humans.

WNV is found throughout Europe, with southeastern Europe and Italy widely affected. WNV cases are significantly lower in Austria, the Czech Republic, France and Germany. In the last 10 years, Germany has introduced different monitoring systems to screen for antibodies and WNV genetic material in birds, chicken eggs, horses and mosquitoes.

The cases in Germany in 2018 and 2019 were all of the same strain, with a specific mutation that may lead to increases disease vitality. The 26-person study team reports that the WNV strain in Germany came from the Czech Republic, most likely before 2018. It is believed that the two very warm summers in a row triggered the 2019 epidemic.

The prevalence of this particular virus indicates that the virus successful overwintered in hibernating mosquitoes. As it is now known that European birds and Culex mosquitoes can transmit the virus, researcher advise international cooperation in the surveillance of birds to provide early epidemic warnings, which could lead to targeted control measures.
