Factors of West Nile

Posted: Updated:

Because we're not seeing more mosquitoes, we're not covering up and spraying ourselves down.

"(It) certainly makes it more likely that they are going to get bitten by an infected mosquito if they're out late at night and aren't wearing any Deet products," said Dr. Mike Hildreth, a Parasitologists at SDSU.

Hildreth has been identifying mosquito-related transmission factors of the West Nile in humans. He says one bite is enough to infect.

"The other factor is your own susceptibility to the virus so not everyone that is bitten is going to get sick," said Hildreth.

In face, 22 of the 67 human cases in South Dakota didn't know they were sick until they donated blood.

Right now is the peak season for the virus, so we all need to be extra cautious.

"Of course if we get an early frost that kills all the mosquitoes then this will end very quickly."
