The Omicron BA.5 variant is now the dominant variant of Covid-19 in the United States among new cases.

But the picture of the pandemic is becoming more blurry as countries report their cases on a less regular basis, according to it New York times.

New federal estimates of new cases showed that BA.5 represented 54 percent of new cases in the United States for the week that ended Saturday, according to the Centers for Disease Control and Prevention.

The new data is based on models and can be changed as more numbers are reported.

Omicron variants BA.4 and BA.5 can evade some antibodies from vaccines and infections, but researchers in South Africa found that the peak in spring did not appear to cause more serious disease than the first wave of Omicron cases in that country.

Most home test results are not included in the data and not all infected people are tested or know they have the virus.

“One of my favorite lines from someone at the CDC is, ‘You don’t need to count raindrops to know how hard it rains,'” Centers Director for Disease Control and Prevention Dr. Rochelle Wallinsky said at a conference in Aspen, Colorado late last month. ”.
