As the omicron variant of the coronavirus drives up infections worldwide, cases do not initially appear as severe as with the delta variant, the World Health Organization said. Still, the global health body warned against categorizing omicron as "mild."
"Just like previous variants; Omicron is hospitalising people and it is killing people," said a WHO tweet quoting its director-general, Tedros Adhanom Ghebreyesus. "In fact, the tsunami of cases is so huge and quick, that it is overwhelming health systems around the world."
A record 9.5 million cases of COVID-19 were confirmed around the world over the last week, a 71% surge in the weekly count of infections, the WHO reported at the Thursday press conference.
WHO emergencies chief, Dr. Michael Ryan, said speculation that omicron might be the last variant of the pandemic was "wishful thinking." He added that "there still is a lot of energy in this virus."
