San Diego County registers first case of COVID-19 with Indian variant – fr


San Diego County has registered its first case of COVID-19 caused by the same variant suspected of overwhelming India, according to the region’s top public health official.
In an update to the County Oversight Board on Tuesday, Dr Wilma Wooten, San Diego’s public health official, said the case was brought to the attention of her department on Thursday, April 29.

A county official clarified after Wooten’s statements that the infection involved a woman in her twenties who had no other medical issues when she returned to San Diego from India in late March. She was hospitalized in early April.

Many obvious questions remain about the region’s first case of B.1.167, the viral variant believed to be behind the heart-wrenching outbreak of COVID-19 in India, which has spiked deaths as many Health care systems are overwhelmed and unable to provide enough supplemental oxygen. to answer the question.

The county health department did not disclose whether the woman was vaccinated when she was infected, how many close contacts she had before testing positive, or whether she remained hospitalized. The long delay between when the patient was hospitalized and when the health department was informed that the Indian variant was the cause is explained, a representative said, by long delays for gene sequencing.

Typically, county health officials have said it can take weeks after a patient tests positive for subsequent sequencing of viral genetic material needed to determine which variant caused a particular case. Since only a relatively small subset of samples from positive tests are sequenced, any identification is considered potentially representative of the larger set, meaning that more B.1.167 cases have likely occurred in the community but were simply not selected for genetic analysis.

The variant remains rare enough in the United States that it has yet to start showing up in the United States Centers for Disease Control and Prevention’s nationwide prevalence estimates. Locally, B.1.1.7, the variant first detected in the UK, remains the most dominant type detected in America, causing around 60 percent of cases, according to the CDC. However, this data is only valid until April 10.

Recent reports have shown the presence of the Indian variant in Michigan and Iowa. Although B.1.167 has many more than two mutations, it is often referred to as a “double” mutant because it shares mutations with other types, including those first spotted in California, South Africa, and Brazil.

It remains unclear, according to a recent update from the World Health Organization, whether the variant is more transmissible or more resistant to vaccination than the other types. The studies are still too small to draw firm conclusions, but increased virulence is possible.

Wooten also said Tuesday that San Diego County also spotted its first case of a variant first detected in New York City. A recent preprinted study found that current vaccines work well against the variant despite initial concerns that a mutation could have made inoculation much less effective.

Although mutant types of coronaviruses have become increasingly prevalent in San Diego County, the overall trajectory of the local pandemic has been stable. There were 186 more positive tests announced in Tuesday’s COVID-19 follow-up report, but some of them, the county said, were associated with a “batch of past tests” that were only sent recently. to the county. There has also been a slight increase in the total number of residents hospitalized for symptoms of COVID-19. This total fell from 138 Sunday to 156 Monday.

Wooten has indicated that the state’s current emergency against COVID-19 is unlikely to end soon, although the state has announced plans to end its current multi-tiered reopening system in mid-June. .

“We have been informed by the state that the state declaration is expected to extend until the end of 2021 to continue and support response efforts, including immunization activities,” Wooten said. .

The county recently announced that three of its community vaccination sites will be open from 1 p.m. to 8 p.m. to allow access for those who cannot make an appointment earlier in the day.

They are:

  • North Coast Live Well Health Center, 1701 Mission Ave., Oceanside, Sunday through Thursday.
  • South Region Live Well Center, 690 Oxford St., Chula Vista, Sunday through Thursday.
  • Eastern Public Health Center, 367 North Magnolia Ave., El Cajon, Tuesday through Saturday.
