Omicron Ba.2 Variant Pressures Parts Of U.S.

Recorded Covid-19 cases remain low nationwide and hospitals treat the smallest number of Covid-19 patients after any increase. Places where cases are rising, including New York, report relatively small increases from recent thresholds. The mixed signals are prompting officials to warn that BA.2 is likely to lead to higher transmission of the virus, but they also hope among public health experts that warming weather and accumulated immunity in the population are reducing the impact of the variant.
