Mosquitoes collected in Newhall have tested positive for West Nile virus, officials said Friday, one week after mosquitoes collected in Canyon Country also tested positive for the disease.

It is the first time this year West Nile virus has been discovered in Newhall by the Greater Los Angeles County Vector Control, the agency said in a written statement.

Mosquitoes collected on Heron Lane in Canyon Country also tested positive for the disease, officials announced Aug. 13.

More positive tests have been found recently because temperatures have been rising throughout Southern California.

So far this year, 11 dead birds and 25 mosquitoes have tested positive for West Nile virus in the vector control district, according to the statement. Across California, 232 dead birds and 676 mosquitoes have been reported to vector control. 

West Nile virus can be transmitted to humans by a mosquito bite but not everyone who is bitten will contract the disease.

The elderly and children are at the greatest risk to contract West Nile.

Mosquitoes breed in stagnant pools of warm water. To prevent mosquitoes from breeding, residents should once a week clean out bird baths, water dishes for pets, rain gutters or any other place water might collect.
