The presence of West Nile virus in area mosquitoes continues to increase in the Inland Empire, officials announced Friday.
West Valley Mosquito and Vector Control District report eight more mosquito samples from Ontario and Montclair tested positive for the virus. The tests were conducted on Thursday.
Vector control districts officials last week predicted there would be a continued activity in the virus in part due to the high temperatures.
“The weather is very conducive for mosquito breeding and virus multiplication in mosquitoes and susceptible wild birds right now, and residents should be performing weekly checks around their property for any standing water,” vector officials said in a statement.
The Ontario samples were collected near Vineyard Avenue and Riverside Drive; Fourth Street near Benson Avenue; Carlos Street near Mission Boulevard; and Walker Avenue near Philadelphia Street, officials said.
In Montclair, the trap was located near San Bernardino and Helena Avenue.
The first trace of the virus in San Bernardino County this year was in Ontario – a dead bird and a sample of mosquitoes collected on June 27.
Statewide there has been one human case, 124 mosquito pools and 106 dead birds that have tested positive for the virus in 2013.
The public is advised to make sure their door and window screens are in good repair. “Green” swimming pools and standing water are breeding grounds for mosquitoes and should be dumped or cleaned.
