DeKalb Board of Health says human West Nile virus cases detected in county

The DeKalb County Board of Health announced that a human case of West Nile virus was detected in the county Wednesday.

Officials said Thursday the case was the first infection in the county for the year, and that no cases of West Nile virus had been detected in DeKalb since 2020, until now.

The confirmed case was detected in a male patient in their 20s, according to a statement from the DeKalb County Board of Health.

Board of Health officials said they are also investigating two unrelated West Nile cases, one in the Lake Claire area and one in the North Druid Hills area.

According to the board, larvicide application has been used in low-lying areas and storm drains throughout the county, including areas where the cases were detected.

Larvicide is a process used to keep young mosquitoes from becoming flying, biting adults, according to the county.

While West Nile, COVID-19, and other similar coronaviruses share similar symptoms, the U.S. Centers for Disease Control and PRevention said no evidence suggests COVID or other coronaviruses are spread by mosquitoes.

Due to the similar symptoms, DeKalb health officials said it is important to have symptoms evaluated by a medical professional, especially if you’ve spent extended time outdoors without wearing insect repellant.
