US Centers for Disease Control and Prevention researchers say three out of every four US children have been infected with the coronavirus and more than half of all Americans have signs of previous infections.
Three out of every four US children have been infected with the coronavirus and more than half of all Americans have signs of previous infections, according to a report from the Centers for Disease Control and Prevention .The percentage of those 17 and under with antibodies rose from about 45 per cent in December to about 75 per cent in February
For Americans of all ages, about 34 per cent had signs of prior infection in December. Just two months later, 58 per cent did. The older people were, the less likely they had evidence of past infections. That may be because older adults have higher vaccination rates and they may be more likely to take other COVID-19 precautions, such as wearing masks and avoiding crowds, Dr Clarke said.
Available evidence nevertheless offers reason to be hopeful about how the pandemic is going, officials suggested.
