Mosquitoes are spreading dangerous dengue in US states. Here’s where to watch out
The Independent • • health
Key Points:
- Dengue virus cases are rising across the U.S., with 1,455 local and travel-related infections reported this summer, including locally acquired cases in Virginia and Florida.
- The virus is primarily spread by Aedes aegypti mosquitoes, which also transmit Zika and chikungunya, and can cause symptoms ranging from rash and aches to severe complications and death in rare cases.
- Climate change and warming temperatures are contributing to the expanded range and increased survival of the mosquito vectors, leading to more dengue cases in the U.S. than the previous decade's average.
- There is no specific treatment for dengue; most patients recover with rest and fluids, while severe cases require hospital care, and a vaccine (Dengvaxia) is available only for certain children with prior infection.
- Preventive measures include using mosquito repellent and wearing protective clothing, as repeated infections are possible and pregnant women face risks of severe fetal outcomes from dengue infection.
