Mosquitoes have been identified in areas of South Bay tested positive for the West Nile virus. Santa Clara, Contra Costa, Sonoma, and Solano have reported West Nile virus activity in these Bay Area communities from infected mosquitoes.

The similarities between COVID-19 and West Nile virus infections include: fatigue, fever, headache, diarrhea, vomiting, and body aches. It’s important to pay attention to early signs of these symptoms so that you can be treated.

In addition, West Nile virus infections stay in the body for three to six days which is close to COVID-19 infection appearing after 2-14 days after exposure. In both cases, it’s advised to stay home to avoid further contact. Despite the similarities, the World Health Organization (WHO) reported that COVID-19 cannot be transmitted by mosquitoes.

In Santa Clara County, there have been positive cases reported. “The district has a surveillance team dedicated to monitoring for the presence of mosquito-borne diseases like West Nile virus,” Beverly Perez, a Vector Control Community Specialist, County of Santa Clara Vector Control District.

There are measures set in place by the district to combat the positive West Nile virus. “If a West Nile virus mosquito is detected, the district initiates an adult mosquito control treatment to reduce the mosquito population in the area,” Perez continued.

The district has implemented a standard protocol to assist people with information about transmission. General notices are provided on various social media sites such as Twitter, Instagram, and Facebook. If the public has additional questions about the West Nile virus, they can contact the district’s West Nile virus hotline at (408)-282-3114.
