Bacteria-infected mosquitoes to be unleashed in US to fight Zika


Today, Verily — formerly Google Life Sciences — began releasing bacteria-infected male mosquitoes in Fresno, California.

The goal is to rid the area of the mosquitoes that have the potential to carry the Zika virus

Verily plans to release 20 million mosquitoes in Fresno starting Friday, according to a story.

The hope is that while mating, these lab-raised mosquitos become sterile and mate with the wild mosquoitoes that are wild and capable of carrying the Zika virus, and their resulting eggs do not hatch.

The bacteria carried by the Verily mosquitoes is considered harmless to humans.

Aedes aegypti mosquitoes, which can transmit the virus, would no longer be able to reproduce.

A year ago, a woman became Fresno County’s first travel-associated Zika case after being bitten while out of the country. Another woman this year became the county’s first confirmed case through sexual contact with a partner who had been traveling.

The Aedes aegypti mosquito has been spreading in the central San Joaquin Valley since 2013 and is particularly widespread in Clovis and parts of Fresno.

As an added bonus, Verily’s infected male mosquitoes don’t bite so Fresno residents won’t have to worry about itching more than usual.

Verily plans to release about 1 million mosquitoes per week over a 20-week period in two 300-acre neighborhoods in the Fresno area — the largest U.S. release to date of those infected with the Wolbachia bacteria.
