History of the West Nile Virus

Where did West Nile Virus come from?

West Nile virus was first isolated in 1937 in the West Nile region in Uganda. The disease has spread through many parts of Europe and Asia as well as North and South.

How does it spread?

We don’t know exactly how the spread of the virus but there are many theories. Probably the West Nile virus was imported to other countries from bird or mosquito that was infected with the disease. The virus has been found in over 150 different species of birds, including: crows, Ravens, blue jays and Newcastle. Out of 74 different species of mosquitoes found throughout Canada, found only ten carry it.

How the West Nile virus?

Mosquitoes become carriers of it after feeding on the blood of birds infected with the virus. And transmitted to people by the bite of an infected with West Nile virus. Recently, scientists discovered that people can be infected with West Nile virus through other methods such as blood transfusion and organ transplantation/tissues. There is, however, no evidence to suggest that can be contracted by kissing or touching a person infected with the disease.

It poses the greatest danger to those with weakened immune systems or chronic diseases and serious health risk issues related to HIV increase with age. It risk greatest during July and August, the peak of the mosquito season. However, it’s good to keep in mind that mosquito season lasts from as early as mid-April, even after the first hard Frost usually in October.
