What do you need to know about mosquito-borne illnesses like the Zika and West Nile viruses? St. Louis on the Air is delving into it on Tuesday.

Facts and fiction continue to swirl about mosquito-borne illnesses like the Zika and West Nile viruses. On Tuesday’s St. Louis on the Air, we discussed what you need to know about such illnesses and how to prevent them.

Saint Louis University is currently at the forefront of trying to develop a Zika vaccine. Sarah George, a researcher with the Saint Louis University Center for Vaccine Development, joined the program on Tuesday to discuss her research and prevention tips.

“There’s been West Nile transmission in the United States since 1999 and in Missouri, there are about 50 cases of West Nile per year reported to the Department of Health,” George said. “Zika has now been reported in every state in the union.”

Those cases of Zika have all been from returning travelers so far.

Zika transmission by mosquitoes has not occurred in the St. Louis area so far, although the mosquito that can transmit the disease is located here, George said. Zika has been transmitted sexually in the St. Louis area, however.

Saint Louis University is currently undertaking a National Institutes of Health-sponsored study of a potential Zika vaccine. The vaccine was developed by Walter Reed Army Institute of Research and is being testing at four sites, including SLU, Harvard, Walter Reed Army Hospital and in Puerto Rico.

It is a whole virus, inactivated vaccine and participants in the study cannot get Zika from it. Thirty healthy adults have been enrolled in the study so far and George is currently looking for 60 more.

“Right now, the NIH and the FDA are hoping to have a Zika vaccine available for general use around 2020,” George said.

The difference between Zika virus and West Nile is that Zika attacks developing neurons in babies still inside their mothers. West Nile, on the other hand, preys on older adults, age 60 and older, and leads to meningitis and encephalitis.

Unfortunately, many of the preventative techniques used to allay mosquito-borne illnesses are not that comfortable in the summer, including wearing long sleeves and long pants. Insect repellants, such as DEET and Picaridin, are also recommended. George pointed to a full list on the CDC website, available here.

For those interested in learning more about mosquito-borne illnesses and what can be done about them, George will give an extended talk about the subject on July 12. Details on the event below.
