West Nile virus

The West Nile virus is spread by infected mosquitoes. Once an individual is bitten by an infected mosquito, the virus is introduced via the saliva of the mosquito into the bite site.

Aside from a mosquito bite, the virus can also be transmitted via breastfeeding, organ transplant, blood transfusion and via the placenta from mother to child.

What are the signs?

Generally, the West Nile virus does not trigger any sickness or simply a mild, self-limiting febrile condition. In most instances, the virus triggers a mild condition known as West Nile fever.

The indications of West Nile fever are strikingly the same as the flu and might include:

  • Headache
  • Fever
  • Skin rash
  • Body aches
