South Park Resident Free of Mosquito-Borne Illness

This was the first time the county has found Aedes larvae close to a suspected case of a mosquito-borne illness.

A South Park resident believed to be suffering from a mosquito-borne illness  has tested negative for dengue, chikungunya and Zika, according to the San Diego County Health & Human Services.

On Friday, county workers sprayed a two-block area of South Park after discovering the larvae from a mosquito known to be a carrier of the Zika virus.

The move to spray was the result of a potential case of a mosquito-borne illness in the area.

On Tuesday, county officials learned the test results came back negative for the three illnesses that pose a potential threat to the surrounding community, according to spokesperson Craig Sturak.

The area involved in the spraying was between 31st and 32nd streets and Grape and Elm streets.

The county sprayed the South Park neighborhood less than 24 hours after notifying residents, leaving some of them upset. Now they know why the county acted so quickly. NBC 7’s Artie Ojeda has more.

A county spokesperson says vector officials look for Aedes larvae and adult mosquitoes each time a suspected case is identified. This was the first time the county has found Aedes larvae close to a suspected case.

County officials want to make it clear, the Aedes larvae did not test positive for any disease, nor were any adult mosquitoes trapped nearby.

There have been 137 cases of the Zika virus reported in the state of California. The only U.S. states reporting more cases are Florida and New York.

The California cases are not local mosquito-borne transmissions, according to the California Department of Health. They have only involved people who contracted the virus while traveling outside the U.S. or through sexual contact with someone who had.

Aedes aegypti (or yellow fever mosquitoes) and Aedes albopictus (or Asian tiger mosquitoes) are known to transmit the virus. These are not native to California.

As of the beginning of August, mosquitoes that can carry the virus have been found in 12 California counties.
