A jump in the number of mosquitoes found with West Nile virus in San Joaquin County has brought new warnings from the San Joaquin County Mosquito & Vector Control District as the San Joaquin Valley heats up.

Aaron Devencenzi, a public information officer for the vector control district, said the number of mosquito samples testing positive for West Nile virus had increased by more than 10 times within three weeks.

“When we were looking at the week of June 24 through the 30th, we only had eight mosquito samples positive for West Nile virus, and as of now — we collected last week — we’re at 89 samples that are positive, so we have had substantial amount showing positive in that three-week period,” Devencenzi said.

Devencenzi said that the rise in temperatures was the likely cause of the increased mosquito numbers this summer.
