West Nile Virus (WNV) is a zoonotic disease caused by mosquitoes, and it prevails in almost all countries. Cases of WNV occur during mosquito season, which starts in summer and continues through fall. Mosquitoes get the infection when they feed on infected birds, and then it transmits the virus to people and other animals. To date, there is no evidence that the virus is transmitted by the cough of an infected person or through any direct contact.
Climate change is one factor which assists the virus to cause an epidemic in certain regions. Most people affected by WNV do not develop any clinical symptoms. It causes flu-like illness such as high fever, headache, neck stiffness, nausea, diarrhea, rashes in some people.
Recently in Israel, the West Nile virus flare-up in summer for the first time in 2020. The Ministry identified the mosquitoes around the Kishon Stream in the Mount Gilboa, carrying the infectious virus. Reports conveyed that nearly 3 Israel people died of the disease in 2018. Even last year, there were 32 human cases reported in 27 localities, and infected mosquito in 34 places throughout Israel.

The Environment Protection Ministry has listed certain guidelines to the public to prevent the spread of the mosquito-borne virus. They focused to increase the monitoring and surveillance to take necessary steps despite the current COVID-19 situation.
