Mosquitoes do not transmit COVID-19 – however they’re nonetheless extra than simply annoying – Pasadena Weekendr


The current surge in COVID-19 cases is fueling renewed public concern about the virus. However, experts say they want to calm people’s minds about a common problem: mosquitoes don’t transmit COVID-19.

Since mosquitoes are able to carry other viruses such as West Nile virus, Zika, dengue, yellow fever, and others, many of the San Gabriel residents are concerned, according to Levy, spokesman for the San Gabriel Valley Mosquito & Vector Control District Valley asked the sun.

Fortunately, all of the research available shows that the pesky insects cannot transmit the virus between people who bite them, he said.

“With the current increase in COVID-19 cases, there is renewed public interest in whether or not mosquitoes can transmit COVID-19. And so far the evidence points to “no,” ”Sun said.

“The difference we can make here is that while the mosquito can carry it, there may be tests that say mosquitoes can carry a particular virus, it doesn’t mean they are able to spread, “he said. The virus can penetrate the mosquito body but cannot be transmitted to humans. “

Sun said he could understand why people would be concerned.

“That would definitely be a game changer if mosquitoes could spread it, but we are very grateful that we were able to avoid that fact through some kind of natural gamble,” he said.

The recent introduction of the Zika virus in Southern California was an example of how viruses can surprise doctors and scientists.

“Zika was the first known mosquito-borne disease that not only spread through a mosquito bite, but can also be sexually transmitted between people. So you never know what nature can throw at you, ”Sun said.

Vector control officials pointed this out A study published in Scientific Reports in July by Kansas State University researchers who found COVID-19 cannot thrive in the bodies of mosquitoes.

“Three common mosquito species; Aedes aegypti, Ae. Albopictus and Culex quinquefasciatus, which are the two major genera of arbovirus vectors that infect humans, were tested, ”the study said. “We show that the SARS-CoV-2 virus is unable to reproduce in these mosquitoes even under extreme conditions and therefore cannot be transmitted to humans, even when a mosquito is unlikely to spread fed to a viremic host. “

While COVID-19 is not one of the dangers posed by mosquitoes, the diseases they transmit remain a serious problem, Sun said.

“The risk is still there, but now that the weather is cooling it’s less,” he said.

When temperatures drop, mosquitos tend to enter sewers underground, Sun explained. “Our underground infrastructure is constantly warm all year round, which is also the perfect place to rest and hide for mosquitoes in winter.

“Our current fear is that people will become complacent in their homes and fill containers with water,” he said. “And if there is ever a warm day in winter, these mosquitoes will come straight out of our storm sewers and lay their eggs in people’s backyards. And mosquitos bloom in winter. “

Officials reminded the public that mosquitoes can use stagnant water as small as a bottle cap to breed in.

While vector control officials have teams to monitor storm sewers and check for mosquitoes if necessary, “we will still rely heavily on residents to be our first line of defense in their own homes to prevent mosquitoes from infecting their yards “Said Sun.
