Two samples of mosquitoes found in traps at Creekside Park tested positive for West Nile virus, the San Gabriel Valley Mosquito and Vector Control District reported Friday.
This is the second time mosquitoes carrying the West Nile Virus have been discovered in the San Gabriel Valley in the past few weeks. The discovery in Walnut follows one in San Marino’s Lacy Park earlier this month, according to mosquito abatement officials.
In Walnut, two of the four samples taken on July 11 tested positive for the virus, said Jason Farned, SGVMVCD spokesman. The San Marino discovery was found during the first week of July, according to the Greater Los Angeles County Vector Control District.
“We expect it every year so it is not a surprise that they are here in the San Gabriel Valley,” Farned said. “It is not a matter of if, but when, every summer.”
Creekside Park is the site of Walnut’s summer concert and movie series, a Tuesday night weekly event which usually attracts 1,000 people, said City Councilwoman Mary Su.
She said the city will hold a press briefing at 10:30 a.m. Monday at Creekside Park, 780 Creekside Drive, to inform residents and advise them on how to take precautions.
