Transmission of the virus

How is the virus transmitted?

The main mode of transmission for WNV is through mosquito bites. Mosquitoes become virus carriers after biting infected birds. Since mosquitoes can bite more than once, they can then transmit the virus by biting another animal or a person.

In rare cases, WNV can be transmitted during an organ transplant or blood transfusion. If you must undergo a transplant or transfusion, your doctor will explain the benefits of these procedures as well as the slight risk of WNV infection.

The virus cannot be transmitted from person to person. It is impossible to contract the virus through kissing an infected person or by treating a patient who is carrying the virus. There is no evidence to suggest that the virus can be transmitted from an infected bird or animal to a person. Mosquitoes are the real culprits!
