Mosquito-borne illnesses are becoming more common in the United States, particularly in southern and coastal areas such as Sylva, North Carolina. Warmer temperatures and increased humidity have led to longer mosquito seasons, allowing populations to grow and viruses to spread over a greater period of time.
New species of mosquitoes like Aedes aegypti and Aedes albopictus are moving into the U.S. South. These mosquitoes can transmit viruses such as Zika, dengue fever, chikungunya, and yellow fever — diseases that were previously limited mostly to tropical regions.
Urban development is also contributing to the problem. New construction and inadequate drainage create standing water in places like streets and yards, providing ideal breeding grounds for mosquitoes. Even small amounts of water, such as what collects in bottle caps or clogged gutters, can support mosquito larvae.
Increased international travel has further complicated efforts to control these illnesses. People infected with mosquito-borne viruses abroad may return home where local mosquitoes bite them and then spread the virus locally.
Common mosquito-borne diseases include West Nile virus (the most frequently reported in the U.S.), Zika virus (which poses special risks for pregnant women), dengue fever (which can sometimes lead to hospitalization), chikungunya (noted for severe joint pain), and Eastern Equine Encephalitis (a rare but serious disease causing brain inflammation).
To reduce risk, health officials recommend using EPA-approved insect repellents containing DEET or other effective ingredients; eliminating standing water from containers around homes; wearing long sleeves and pants outdoors; installing screens on doors and windows; maintaining yards by trimming shrubs and mowing grass regularly; and considering larvicides or other treatments for outdoor spaces.
Vulnerable groups include pregnant individuals, young children, older adults, and people with weakened immune systems or chronic conditions. Symptoms of infection may include fever, rash, joint pain, fatigue or neurological symptoms such as confusion or headache. Anyone experiencing these after a mosquito bite should seek medical attention at facilities like Harris Regional Hospital in Sylva.
Local residents are advised to follow updates from health departments regarding mosquito control measures. Harris Regional Hospital states: “At Harris Regional Hospital, we’re committed to keeping Sylva, North Carolina healthy and informed. Whether you need treatment, prevention advice, or peace of mind, we are here for you.”
