As of Tuesday, over 5.07 million COVID-19 cases and 75,500 deaths have been registered in California since the beginning of the pandemic, local authorities said. However, according to Johns Hopkins University, the total number of COVID-19 infections in the state had already exceeded 5.3 million.
California is followed by Texas, which, according to the university, has reported over 4.5 million of COVID-19 cases and 75,500 deaths.
Johns Hopkins University said that over 53 million cases of COVID-19 infection and more than 820,000 deaths had been registered in the US in total since the beginning of the epidemic.
The current increase in the daily number of COVID-19 cases in the US is thought to be caused by the spread of the Omicron coronavirus strain. The US Centers for Disease Control and Prevention announced on Tuesday that the Omicron variant accounted for 58.6% of all new infections in the country in the week before December 25.
Omicron was first detected in South Africa in late November. The World Health Organization designated it a "variant of concern" due to an exceptionally high number of mutations. Despite multiple travel bans on Africa, the new variant has since been detected in Europe, Asia, and the Americas. Health experts from various countries say the Omicron variant is much more transmissible, but produces milder symptoms.
