Experts are still learning about COVID-19. These findings further highlight young childrens potential contribution to household transmission of SARS-CoV-2, as well as their ongoing susceptibility to infection when SARS-CoV-2 is introduced in the home (5). Upping the ante is the fact that recent subvariants like BA.4 and BA.5 are the most immune-evasive yet, with the ability to dodge antibodies from both vaccines and prior infection. Analysis of AR among household contacts excluded eight persons with unknown case status (persons for whom it was not known whether COVID-19compatible symptoms were present and whether SARS-CoV-2 testing had occurred [or if testing occurred, the results were unknown]).

In addition, surfaces may play a greater role in Omicron transmission. No. Heres how that might affect crucial funding, access to tests, and case counts. In addition, surfaces may play a greater role in Omicron transmission. In just over five months, there were 22,334 confirmed SARS-CoV-2 Omicron infections, 31 hospitalizations and no COVID-19 deaths.
