Cases have been rising across the United States, with the new Omicron subvariant accounting for the majority of new infections. Although health authorities are confident that BA.2 will not cause a surge as bad as its predecessor, they are beginning to put up our defenses by reinforcing mask mandates.
Researchers in Hong Kong studied the severity of the BA.2 variant among a small number of children who were hospitalized for the most recent COVID-19 strain. They found that children who were hospitalized with the BA.2 variant were 18 times more likely to be admitted to the ICU and seven times more likely to die compared to those hospitalized with the flu.
The Centers for Disease Control and Prevention has identified 10 early cases of people with prior COVID-19 infections who were consequently reinfected with Omicron. This finding raises questions about how long super immunity lasts.
