Remember that ‘other virus’? It’s time to take precautions aginst West Nile - Woodland Daily Democrat

Remember that other virus? The one we used to worry about before coronavirus?

Well, it's back. In fact, West Nile Virus never went away and with rains across the Sacramento Valley over the past weekend and the weather warming it's time to take precautions against potentially deadly mosquitoes.

On Monday, Gary Goodman, district manager for the Sacramento-Yolo Mosquito and Vector Control District, warned that stagnant water, coupled with warmer weather can create the perfect combination for mosquitoes to breed.

Fortunately, this first wave of mosquitoes isn't as dangerous as those carrying West Nile, but those other mosquitoes aren't far behind.

"It's been a wet March and we've had a significant amount of rain these last few days," said Goodman. "Mosquitoes complete their life cycle much faster in warm weather. We urge all residents to do their part and drain all sources of standing water from common backyard sources such as buckets, flower pots, birdbaths, old tires and other small containers that may breed mosquitoes.

"Getting rid of areas where mosquitoes can breed now, will go a long way later in the season," indicated Goodman.

February was a dry and warm month where there was a marked increase in mosquito activity. In fact, the past three months have been drier than usual, sparking fears of another drought in California.

The mosquitoes, meanwhile, love the combination of wet and dry weather. These mosquitoes are ones that had been hibernating during the past few months and while they were aggressive day-biting mosquitoes, fortunately, they are not the same species that can transmit West Nile virus and are considered only a seasonal nuisance.

However, it won't take long to those West Nile mosquitoes to return, along with their equally dangerous relatives, which spread Zika along with dengue, yellow fever and more.

Two invasive species of mosquitoes that can carry Zika, dengue, yellow fever and other dangerous viruses have been spreading in California — and have been found as far north as Sacramento and Placer counties.

There are now 16 counties where Aedes aegypti, commonly known as the yellow fever mosquito, has been detected, according to the state Department of Public Health. Five of those counties have also detected Aedes albopictus, the Asian tiger mosquito.

The Sacramento-Yolo Mosquito and Vector Control District announced back in September that it has detected the invasive mosquito Aedes aegypti in a new area of Citrus Heights.

These mosquitoes, distinguished from other species because they primarily sip human blood during the day instead of at night, can spread the Zika virus, which infected more than 1 million people during an epidemic that began in 2015 in Brazil. The virus also can spread during sex.

More than 3,000 babies were born with microcephaly in Brazil during the epidemic. Microcephaly is a condition in which a baby's head is much smaller than expected, and can occur because the baby's brain has not developed properly.

In California, these invasive mosquitoes were detected in 2011 in Los Angeles County, and since have spread northward into the Central Valley.

Although the invasive mosquitoes now inhabit a large swath of the state, authorities have recorded no cases of "local transmission" of the dangerous viruses, which means there's no evidence these Aedes mosquitoes in California are carriers. The California residents who have fallen ill with the dangerous viruses became infected during international travel to areas where the viruses are endemic.

But the potential for in-state transmission remains.
