Protect Yourself from West Nile Virus: Houston Reports Increase in Mosquito Activity
Summer is in full swing, and along with the heat, Houston is also experiencing a rise in West Nile virus cases. Harris County recently reported a significant increase in the number of West Nile-positive mosquitoes, with 235 positive samples already recorded this year compared to only 50 in 2023.
Adding to the concern, Montgomery County health officials have reported “abnormally high levels” of West Nile virus and confirmed their first human case of 2024. This case, once confirmed by the state, will be Texas’ first human case of the year.
Infectious disease expert Dr. Peter Hotez noted, “The fact that they’re picking up more positive mosquitoes is a cause for concern.” He emphasized the importance of being prepared for a potential increase in West Nile virus cases as summer progresses.
Montgomery County’s first human case this year is a woman in her 50s residing in the 77304 ZIP code. Hotez warned that as we move further into the summer, the situation could worsen, potentially leading to a challenging West Nile virus year.
Looking back on Texas’ worst outbreak in 2012, which saw nearly 1,900 cases and 89 deaths, Hotez underscored the importance of taking preventative measures to avoid contracting West Nile virus.
While many people may not experience symptoms, those who do may suffer from fever, headache, body aches, nausea, and vomiting. Severe cases can result in intense headaches and confusion, indicating a more severe form of the virus.
Harris County has already implemented evening spray operations in an effort to curb mosquito activity. Hotez commended their efforts, stating, “They know how to do this really well.” However, with Houston’s extreme heat and recent rainfall, the conditions are ripe for an increase in mosquito activity and potentially more mosquito-borne diseases in the coming months.
As a precaution, health officials recommend wearing protective clothing when outdoors, especially during peak mosquito activity times in the early morning and late evening. Using mosquito repellent with Deet on exposed skin can also help prevent mosquito bites and reduce the risk of contracting West Nile virus.
