Chikungunya Virus
Chikungunya (pronunciation: chik-en-gun-ye) virus is
transmitted to people by mosquitoes; specifically
the
Aedes aegypti and
Aedes albopictus
mosquitoes. The most common symptoms of chikungunya
virus infection are fever and joint pain. Other symptoms
may include headache, muscle pain, joint swelling, or
rash. Outbreaks have occurred in
countries in Africa, Asia, Europe, and the Indian
and Pacific Oceans. In late 2013, chikungunya virus was
found for the first time in the
Americas on islands in the Caribbean. On July 16,
2014, the first locally acquired cases in the
continental United States was identified in Florida.
Chikungunya virus is not currently found in mosquitoes
in Los Angeles County. There is a risk that the virus
will be imported to new areas by infected travelers.
There is no vaccine to prevent or medicine to treat
chikungunya virus infection. Travelers can protect
themselves by
preventing mosquito bites. When traveling to
countries with chikungunya virus, use insect repellent,
wear long sleeves and pants, and stay in places with air
conditioning or that use window and door screens.

Reporting Mosquito Breeding Sites and Areas with Water
Accumulation
Acute Communicable Disease Control is responsible for
monitoring and addressing human health problems in Los
Angeles County, but is not directly involved with
mosquito control activities. This important action is
under the control of the county’s five independent
mosquito control (abatement) districts. Beyond our
county, the Health Departments of Long Beach and
Pasadena also operate their own mosquito control
programs.
To report a potential mosquito breeding situation,
please contact the appropriate Mosquito Abatement
District or city public health department:
