Learn about new viruses detected in the San Francisco Bay area of ​​India



A new case of the virus first detected in India was detected in the San Francisco Bay Area last week, and seven more cases are expected.

According to KRON, the clinical virology laboratory of the Stanford University Health Care Institute detected the variant and believes it is the first variant found in the United States.

The variant found in India has a combination of two mutations in the spike protein, which has been identified in other variants: the L452R mutation first discovered in California is believed to transmit more than 20%, while the dominant E484Q in Brazil.

The virus has been mutating throughout the pandemic. Most mutations are trivial, but scientists have been studying which mutations may make the virus more likely to spread or make people sick. The first variants discovered in South Africa, the United Kingdom, Brazil, and California have been designated as “variants of concern”

; by the Centers for Disease Control and Prevention. All these variants have been detected in the Bay Area.

Early research shows that vaccines can provide protection against new variants, although their effectiveness may be slightly lower and further research is needed.

The Indian variants are mainly found in the country’s Maharashtra state, and the Ministry of Health said in a statement that 15% to 20% of the samples sequenced in the region will find such variants.


Dr. Peter Chin-Hong, an infectious disease expert at UCSF, told KCBS on Monday morning that there is no conclusive evidence that it spreads more easily.

Chin-Hong said: “My intuition is that these vaccines will be able to fight against this Indian variant.” “Last week we got Pfizer’s data on the South African variant. It’s a bit similar, and I hope it will also work.”

Researchers at Stanford University screened hundreds of virus samples collected from people in the Bay Area and sequenced the entire virus genome to identify new mutations in key viral proteins.

“In most cases, it is too early to say whether or how these variants affect the pandemic, but it is important to monitor their evolution and spread,” said Benjamin Pinsky, an associate professor of pathology and epidemiology of the disease. Benjamin Pinsky) said in a statement. “Our surveillance tests are specifically designed to screen virus samples on a large scale to identify specific strains circulating in the Bay Area and throughout California.”
