Infections, deaths rising globally as variants spread

The number of new coronavirus cases rose by 18% in the past week, with more than 4.1 million cases reported globally, according to the World Health Organization.

The U.N. health agency said in its latest weekly report on the pandemic that the worldwide number of deaths remained relatively similar to the week before, at about 8,500. COVID-related deaths increased in three regions: the Middle East, Southeast Asia and the Americas.

The biggest weekly rise in new COVID-19 cases was seen in the Middle East, where they increased by 47%, according to the report released late Wednesday. Infections rose by about 32% in Europe and Southeast Asia, and by about 14% in the Americas, WHO said.

WHO Director-General Tedros Adhanom Ghebreyesus said cases were on the rise in 110 countries, mostly driven by the omicron variants BA.4 and BA.5.

“This pandemic is changing, but it’s not over,” Tedros said this week during a news briefing. He said the ability to track COVID-19’s genetic evolution was “under threat” as countries relaxed surveillance and genetic sequencing efforts, warning that would make it more difficult to catch emerging and potentially dangerous new variants.

He called for countries to immunize their most vulnerable populations, including health workers and people over 60, saying that hundreds of millions remain unvaccinated and at risk of severe disease and death.

Tedros said that while more than 1.2 billion COVID-19 vaccines have been administered globally, the average immunization rate in poor countries is about 13%.
