Record 9.5 million COVID-19 cases worldwide last week

Omicron-fueled surge

Dr. Anthony Fauci said multiple studies indicate that the omicron variant appears to cause a milder form of COVID-19.

GENEVA - The World Health Organization said Thursday a record 9.5 million cases of COVID-19 were tallied around the world over the last week, noting a 71% surge in the weekly count of infections amounting to a "tsunami" as the new omicron variant sweeps worldwide.

However, the number of recorded deaths fell, with 41,178 recorded last week compared to 44 680 in the week before that.

"Last week, the highest number of COVID-19 cases were reported so far in the pandemic," WHO Director-General Tedros Adhanom Ghebreyesus said. He said the WHO was certain that was an underestimate because of a backlog in testing around the year-end holidays.

The U.N. health agency, in its weekly report on the pandemic, said the weekly count amounted to 9,520,488 new cases.

While omicron appears to be less severe than the delta variant, especially among people who have been vaccinated, the WHO chief said: "It does not mean it should be categorized as mild. Just like previous variants, omicron is hospitalizing people, and it’s killing people."

"In fact, the tsunami of cases is so huge and quick that it is overwhelming health systems around the world," the WHO chief told a regular news briefing.

The WHO said the rises in case counts over the last week varied, doubling in the Americas region, but rising only 7% in Africa.

The WHO emergencies chief, Dr. Michael Ryan, said speculation that omicron might be the last variant of the outbreak was "wishful thinking" and cautioned: "There still is a lot of energy in this virus."

Added Maria Van Kerkhove, WHO’s technical lead on COVID-19: "I think it’s very unlikely that omicron will be the last variant that you will hear us discussing."

WHO officials called on the public to step up measures to fight the pandemic like getting vaccinated, ventilating rooms, maintaining proper physical distancing and wearing masks — but properly.

"I’m struck by how people actually are wearing masks" Van Kerkhove said.

"Wearing a mask below your chin is useless. And it gives you a false sense of security that you have something on that is protecting you. It will not ... Basically, we are asking everyone to play a part in this."

Separately, Ryan said the WHO’s work with the International Olympic Committee and China — which is set to host the 2022 Winter Games — led him to be "confident" that the measures that games organizers have put in place were "very strict and very strong."

"We don’t at this point see any increased risk of disease transmission in that context," Ryan said.
