Dengue Fever Cases Surge, Becoming 'New Normal' in the U.S.
Imagine tiny bugs called mosquitoes are spreading a sickness called dengue fever.
It's like the flu, but you get it from mosquito bites.
The number of people getting sick in the US has almost doubled!
California, Florida, and Texas are seeing a big jump.
This is because the mosquitoes that carry the sickness are spreading to more places, especially where it's warm.
Doctors are worried because the mosquitoes seem to be here to stay, making dengue fever a common thing.
They think the changing climate is helping these bugs thrive.
Dengue fever cases nearly doubled across the U.S., with a significant increase in local transmissions.
The CDC reported approximately 3,700 new dengue infections in the contiguous U.S. last year.
California experienced a threefold increase in cases, including locally acquired infections.
The Aedes mosquitoes, which transmit dengue, have expanded their territory.
Health officials believe dengue fever has become a 'new normal' due to the persistent mosquito population.
