La Plata County
The first human case of West Nile virus in La Plata County for 2025 was reported in July to the La Plata County Public Health Department (LPCPHD). The case serves as a reminder to residents and visitors to take precautions to protect themselves and their families.
West Nile virus is commonly spread by infected mosquitos. The time between the mosquito bite and symptom onset can be from two to 14 days.
Most people infected with West Nile virus do not develop any symptoms. For those who do, symptoms often include fever, headache, body aches, joint pains, vomiting, diarrhea or rash. Severe illnesses are rare but can include high fever, headache, neck stiffness, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. People over 60 years of age or with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease or who have received organ transplants are at greater risk. Severe infections can result in permanent brain damage or death.
There is no treatment for the virus other than supportive care, and there is no vaccine to prevent it. If you think you or a family member has West Nile virus, consult a health care provider.
Protect yourself from West Nile virus by using insect repellents, limiting activities where and when mosquitoes are active, wearing protective clothing and mosquito-proofing your home. For more information about insect repellents visit the EPA’s
