Mosquitoes Prob­lem­atic For Escalon, Farm­ing­ton

Escalon Times - - FRONT PAGE - By MARG JACK­SON mjack­son@escalon­times.com

Health of­fi­cials re­ported another new case of hu­man West Nile Virus in San Joaquin County this past week – neigh­bor­ing Stanis­laus re­ported five – and of­fi­cials are re­mind­ing res­i­dents to con­tinue to take pre­cau­tions against mosquitoes that can carry the ill­ness.

“This year we have seen an over­all higher pop­u­la­tion of mosquitoes than last year and also a higher pop­u­la­tion than the fiveyear av­er­age through­out the en­tire county,” noted San Joaquin County Mos­quito and Vec­tor Con­trol Dis­trict spokesman Aaron Deven­cenzi.

Both the Escalon and Farm­ing­ton ar­eas have had mos­quito sam­ples test pos­i­tive for WNV in the past week and the re­gion has had both ground and aerial spray­ing in an ef­fort to con­tain the pop­u­la­tion.

And even as the weather starts to cool, Deven­cenzi said the fluc­tu­a­tion in tem­per­a­tures – into the 90s one day, drop­ping to the 70s the next – can lead to more mosquitoes.

“Peo­ple still need to take pre­cau­tions,” he said, not­ing that preven­tion with in­sect re­pel­lent, lim­it­ing stand­ing wa­ter on your prop­erty and wear­ing long sleeves can help res­i­dents pro­tect them­selves.

The mos­quito ‘sea­son,’ he added, typ­i­cally runs through Novem­ber in San Joaquin County.

Some are pas­ture mosquitoes that are more of a nui­sance but don’t carry the dis­ease, oth­ers are those that have West Nile and can pass it on to hu­mans.

“Each year West Nile Virus tends to be more preva­lent in some ar­eas than oth­ers, that changes year to year,” he added, not­ing that Escalon and Farm­ing­ton have had mul­ti­ple sam­ples test pos­i­tive over the last cou­ple of months.

“This is some­thing we are con­tin­u­ing to mon­i­tor, con­tin­u­ing to treat,” he said.

Of­fi­cials have also re­ported one horse be­ing di­ag­nosed with West Nile.

The horse sur­vived, said Deven­cenzi, and there have also been con­firmed cases of 16 birds test­ing pos­i­tive for WNV this year.

“For­tu­nately this year we have had less hu­man cases than last year,” he added.

Traps to col­lect mosquitoes are put out on Mon­days, with test Satur­day

ing of the sam­ples done on Tues­days, with a de­ci­sion then made on Wed­nes­days whether to do spray­ing if pos­i­tive sam­ples are found.

Across the state, noted San Joaquin County Public Health Depart­ment spokes­woman Krista Dom­mer, there were 44 new hu­man

cases of West Nile re­ported last week. The high­est num­ber, 12, was in Los An­ge­les County. Fresno County (3) and Ven­tura County (1) re­ported their first cases of the year.
