The Omicron BA.2 sub-variant now has the highest incidence in the country, with the number of BA.2.12.1 sub-variants increasing especially in the Northeast.
But even those numbers do not offer a complete picture of the virus in the country, CDC officials said on Tuesday. A soon-to-be-published CDC study indicates that about three infections per case were reported from December to February, depending on the region, said Christy Clark, co-chair of the agency’s COVID-19 Epidemiology and Surveillance Working Group. At a briefing with journalists.
The increase in antibody availability from 43 percent of Americans in January to 57 percent in February was also faster than CDC officials had expected.
Clark warned that the fact that most Americans now have antibodies does not guarantee protection against re-infection or any form of group immunity, noting that there is still no known barrier by which the virus stops circulating.
Especially in children, Covid-19 can be severe, with 20 to 30 percent of children hospitalized with the virus being transferred to intensive care units and children developing post-Covid conditions, Clark noted.
“As a pediatrician and parent, I will continue to advocate for children to be vaccinated, even if they have been infected before,” he said.
Vaccination rates are very low, especially in children Only 35 percent Children aged 5 to 11 years who have received at least one dose and vaccination Still unavailable For children under five.
