Mosquitoes In South Carolina Test Positive For West Nile Virus


west-nile-virus-in-south-carolinaAccording to a new press release by The South Carolina Department of Health and Environmental Control (DHEC), several samples of trapped mosquitoes in Beaufort County, SC have tested positive for the West Nile Virus.

DHEC was first notified of the Beaufort County area virus-positive mosquitoes on June 23rd.

“As the state’s public health agency, we partner with jurisdictions across the state to help trap and identify mosquitoes carrying diseases that can be spread to humans. The virus actually starts with a bird. It spreads when a mosquito bites a bird that has the virus in their blood. The mosquito then can spread the virus to other birds, animals or people, when it bites during feeding.”

“We have strategically applied public health insecticides in Beaufort County” said Gregg Hunt, Beaufort County Mosquito Control Director. “Our trucks operate during nighttime hours when these mosquito species are most active. The insecticide that we use is very effective, and was selected because it should have a quick knockdown.”

“The mosquito carrying this virus is usually active at night, but can also be active at dusk and dawn and in shady areas during the day,” Evans said.

What are the symptoms of West Nile virus disease?

  • No symptoms in most people. Most people (70-80%) who become infected with West Nile virus do not develop any symptoms.
  • Febrile illness in some people. About 1 in 5 people who are infected will develop a fever with other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash. Most people with this type of West Nile virus disease recover completely, but fatigue and weakness can last for weeks or months.
  • Severe symptoms in a few people. Less than 1% of people who are infected will develop a serious neurologic illness such as encephalitis or meningitis (inflammation of the brain or surrounding tissues). The symptoms of neurologic illness can include headache, high fever, neck stiffness, disorientation, coma, tremors, seizures, or paralysis.

“If you have concerns about the virus or develop symptoms, you should contact your health care provider,” Bell said.

DHEC is urging residents in South Carolina to pay attention to any standing water on their properties, including flowerpots, gutters, buckets, pool covers, birdbaths and pet bowls. The EPA recommends using natural BTI on standing water to quickly kill mosquito larvae.

They also encourage people wear insect repellent containing DEET, picaridin, essential oil of lemon eucalyptus, or IR 3535 before going outside on humid days.
