Mosquito-borne illnesses are increasing in northern regions such as Johnstown, Pennsylvania. Experts attribute this rise to longer and warmer seasons, increased rainfall leading to more standing water, and the northward migration of mosquito species like Aedes aegypti. These mosquitoes can transmit diseases including dengue, Zika, and chikungunya.
Local health officials note that West Nile virus remains the most common mosquito-borne illness in northern states. Severe cases may cause encephalitis or meningitis. Eastern equine encephalitis, though rare, is very serious and found near wetlands and wooded areas. La Crosse encephalitis often affects children in rural areas. While Zika and dengue are rare locally, they can occur when travelers return from tropical regions carrying these viruses.
People at higher risk for complications include infants, children, older adults, pregnant individuals, and those with compromised immune systems or underlying conditions.
To reduce risk of infection, public health guidance includes using EPA-registered insect repellents before outdoor activities; removing standing water from yards weekly; wearing long sleeves and pants during peak mosquito hours; ensuring window and door screens are intact; and taking extra precautions when traveling to tropical locations by packing repellent and consulting CDC travel advisories.
Common symptoms of mosquito-borne illnesses include fever, rash, headache, nausea, joint pain or fatigue. Medical attention should be sought if these symptoms develop within days of a mosquito bite.
Conemaugh Health System in Johnstown offers prevention advice and care for those affected by mosquito-borne illnesses. The organization emphasizes its commitment to supporting community health throughout the year.
