Report shows omicron's rapid spread in NYC
Omicron became the dominant variant in New York City within five weeks after it was first detected, according to a new report released Thursday by the city's health department.
By comparison, it took 20 weeks for the delta variant to become dominant.
The report, which details preliminary findings on the city's omicron wave, found that there have been lower hospitalization rates but more total hospitalizations compared to the delta wave due to "significantly greater case numbers."
Unvaccinated New Yorkers were more than eight times more likely to be hospitalized than those who were fully vaccinated early in the omicron wave, the report found. Black New Yorkers and people ages 75 and older also were more likely to be hospitalized.
Study finds higher risk of COVID-19 complications for unvaccinated pregnant women
Unvaccinated pregnant women with COVID-19 and their newborn babies have a higher risk of complications from the disease compared with those who are vaccinated, a new study found.
In the study, published Thursday in Nature Medicine, researchers from Public Health Scotland looked at vaccination rates and COVID-19 outcomes in 131,875 pregnant women in Scotland between Dec. 8, 2020, and Oct. 31, 2021, when the delta variant was dominant.

The study reiterates the importance of pregnant women getting vaccinated against the virus due to a greater risk of dangerous health complications from COVID-19. A growing body of research has shown the vaccines to be safe and effective for pregnant women.
