"Residents should empty water from containers of any size and flush out bird baths every week", The Marion County Health Department said.

State epidemiologist Joshua Clayton says South Dakotans need to protect themselves against the mosquito-borne virus, especially during evening outdoor activities such as Fourth of July fireworks shows. Despite no human cases reported of the disease so far in 2019, ISDH expects to see increased West Nile activity throughout in as summer progresses.

Residents are also encouraged to take precautions to prevent exposure to mosquitoes by eliminating breeding sites and standing water on their properties, and wearing insect repellent containing deet.

The Central District Health Department said mosquitoes trapped in Elmore County have tested positive for the West Nile Virus.

On June 21, the individual began exhibiting symptoms of meningitis.

In 2018, 61 people were infected by West Nile virus, marking the highest number of cases ever reported in the state, according to a department of health report.

Less than one per cent of people infected with the virus become seriously ill. Mild symptoms include flu-like illness with fever, headache, body aches, nausea and sometimes swollen lymph glands, or skin rashes on the chest, stomach and back. People over the age of 50 and people with weak immune systems are at greater risk of developing severe illness.

"Anywhere that collects water can breed mosquitos, so checking flower pots, pet food and water dishes, birdbaths, swimming pool covers and other places can reduce the risk of mosquito bites and the illnesses they can carry", McCabe said.
