This was the first case of Ómicron infected in San Diego

The first locally transmitted case of the highly contagious Omicron variant was detected on December 10 in a young man fully vaccinated with three doses against Covid.
That case of local contagion was found just a day after authorities found the first case of Ómicron in the county in a person who had recently traveled abroad.
No relationship was found between the first case in the county on December 9 and the first infected on December 10.
According to officials from the county Health and Human Services Agency and scientists from the University of California, San Diego (UCSD) and Scripps Research, the first case of infection locally was a “man in his 30s.”
The patient, they jointly reported, “has no known travel history or exposure.”
This unidentified man “had mild symptoms, which have resolved, but remained at home in isolation. It did not require hospitalization. He was fully vaccinated and had received his booster shot two weeks before the infection was diagnosed. “
“With this first known case of Omicron acquired in the community, it is clear that the variant is here and will spread,” said Christopher Longhurst, UCSD Health medical director.
“That means you need to continue to apply precautions, measures and common sense, perhaps even more than before,” emphasized the scientist.
The two people, both that locally acquired Omicron case and the first found 24 hours earlier in San Diego County, were fully vaccinated with booster doses when they contracted the new variant.
The scientists felt that it was because they both had all their vaccinations that their symptoms were mild.
But on the other hand, the scientific community in San Diego warned that although fully vaccinated residents may experience only non-dangerous symptoms, they are potential carriers of the Omicron strain virus that is up to dozens of times more contagious than the Delta variant.
“Since we are seeing a lot of Omicron infection in vaccinated people, and even recently boosted, we must take a multi-pronged approach,” said Laurent.
“This includes not only vaccination and boosting, but also masking and
social distancing, serial tests in high-risk situations (such as group homes, dormitories and schools), immediate isolation and tests for anyone who has symptoms, even minor ones such as headaches or mild fevers, ”he recommended.
