Masking and Isolate Omicron Spread Reduce Indoor, CDC Detects

The Omicron variant of the coronavirus is so contagious that it may have been concluded in advance that if one member of the household gets sick, others living there will also contract the virus.

But that turns out to be less certain: the Centers for Disease Control and Prevention’s household study released on Friday showed that when the first infected person wears a mask and is in a separate room at least part of the time, the risk of other family members catching the virus becomes markedly lower. .

Vaccinated people who are infected are also significantly less likely to spread the virus to other members of their household than unvaccinated people.

However, the study highlights how strongly the Omicron variant has spread within a home, especially among people living with children under the age of 5 who have tested positive. Children who were not yet eligible for the vaccine, and who had frequent close contact with their parents or loved ones, spread the virus to 72% of household contacts identified in the study. — the highest rate of any age group, the CDC said.

“These findings further highlight the potential contribution of young children to family transmission,” the CDC scientists wrote in the report.

Federal regulatory agencies are waiting for data on the effectiveness of three doses of Pfizer-BioNTech coronavirus vaccine in children under 5 years of age before deciding whether to allow vaccination for that age group.

The CDC study was based on 183 households in four states where someone was infected with the Omicron variant between November and early February. After interviewing household members about vaccination and infection histories. their infection, any precautions in the home, and whether they tested positive or got sick, CDC scientists determined that the variant had spread in about two-thirds of households. that they identify.

But when the first infected person was fully vaccinated, only about 44% of family members developed Covid, compared with 64% when the infected person was unvaccinated, the study found.

And when the initial member of the infected household was at least in the room alone, only 41 percent of other household members were infected, compared with 68 percent in those who were not isolated. . Wearing a mask by an infected person also reduces the chance of transmission from 69% to 40%.

The study’s authors note that accurately determining the risk of the virus spreading in the home is difficult. They excluded cases where it was not clear who first developed Covid, and did not perform the genetic sequencing necessary to know for sure that people got the virus from an infected person in their home and not at other gatherings.
