In southeastern Saskatchewan, two human beings have been bitten by Culex tarsals. Culex tarsals is a hot-weather mosquito and is responsible for the transmission of West Nile virus in human beings.

The two men are between 45 and 55 years and developed minor symptoms. They are being treated and will soon recuperate.

In 2007, as many as 2,000 cases of West Nile were registered all over Canada and the number reduced to 36 in 2008. The number of cases since then has gone down significantly.

According to Public Health Department, a group of mosquitoes have been tested positive for the West Nile virus in east Hamilton region. This is for the first time that Hamilton area has been reported to have positive mosquito traps or human cases.

In the year 2009, no mosquitoes with the virus were detected.

People infected with West Nile virus have been found to have no serious symptoms and only having mild illness or fever. Although, some people can suffer from inflammation of the brain, can develop polio-like symptoms and can even die. The older people and people who have weak immune system are most susceptible to the virus.

West Nile first came to North America in the year 1999 and New York City was the first city to have human cases. Almost seven people died of the deadly virus.
