LOS ANGELES – Los Angeles County Department of Public Health (Public Health) has confirmed the first case of sexually transmitted Zika infection in a resident of Los Angeles County. A male resident, who traveled to Mexico, developed symptomatic Zika infection in early November. His female partner, who did not travel, subsequently developed symptomatic Zika infection after his return to Los Angeles County.
In Los Angeles County, vector control agencies routinely test mosquitoes that can carry Zika in LA County. There have been no cases of Zika transmitted by local mosquitoes in Los Angeles County. Since 2015, there have been 122 cases of Zika infection reported in the county, out of which 121 have been acquired from the bite of an infected mosquito during travel to areas where Zika is occurring.
“This case is a reminder to take precautions during sex or avoid sex if you or your partner have traveled to an area with risk of Zika,” said Jeffrey Gunzenhauser, MD, MPH, Interim Health Officer for Los Angeles County. “Sexual transmission of Zika can occur with or without symptoms. Given the risk for birth defects, the greatest concern is transmission of the virus to women who are pregnant or attempting to become pregnant.”
To prevent sexual transmission of Zika, couples should use condoms or abstain from sex for 6 months after a male partner has been exposed to or diagnosed with Zika, and for 8 weeks after a female partner has been exposed to or diagnosed with Zika. Pregnant women should use condoms or abstain from sex for the entire duration of their pregnancy.
Transmission of Zika virus is still ongoing in Mexico, Latin America and other regions of the world. Travelers should take precautions against Zika during travel by avoiding mosquito bites including using EPA (Environmental Protection Agency) approved mosquito repellant and wearing long sleeves and pants, and for 3 weeks after returning to prevent infecting local mosquitoes. Symptoms of Zika are fever, joint pain, rash, red eyes and muscle pain beginning 3–7 days after being infected. Illness is usually mild with symptoms lasting up to a week. Most people who are infected have no symptoms at all. People are rarely hospitalized or die from this disease.
Aedes mosquitoes, the mosquitoes that can carry Zika, have been found in many areas of Los Angeles County. People can reduce the spread of Aedes mosquitoes by eliminating all sources of standing water around their homes where mosquitoes can breed, including flower pot saucers, old tires and buckets. Mosquito problems can be reported to local vector control districts.
