Local surveillance systems continue to detect West Nile Virus (WNV), and St. Louis Encephalitis virus (SLEV) in mosquito collections across Lubbock County. In addition, healthcare providers in the community are reporting patients with symptoms consistent with mosquito-borne illnesses, including fever, headache, body aches, and fatigue. These reports, combined with positive mosquito samples, underscore the importance of prevention.
“Finding St. Louis Encephalitis in our mosquito population and hearing from providers about possible cases are reminders that residents should take precautions against mosquito bites,” said Katherine Wells, Director of Public Health. “These viruses are active in our area, and simple steps like using insect repellent and draining standing water can help protect you and your family.”
About the Viruses
- WNV and SLEV are bird diseases. Humans are exposed when bitten by mosquitoes that previously fed on infected birds.
- Not spread person-to-person. These viruses are only transmitted through infected mosquito bites.
- Most infections are mild. Symptoms can include headache, fever, muscle and joint aches, nausea, and fatigue.
- Severe illness is rare. In some cases, the viruses may cause central nervous system infections with symptoms such as neck stiffness, disorientation, tremors, convulsions, muscle weakness, or paralysis.
- Many people have no symptoms. Up to 80% of those infected never develop illness.
There are no medications or vaccines for West Nile Virus or St. Louis Encephalitis. People over age 50 and those with existing health conditions are at higher risk of serious illness. Anyone who develops symptoms and suspects WNV or SLEV infection should contact their healthcare provider…
