Coronavirus: WHO sees more proof Omicron is milder in ‘decoupling’ between cases and deaths
- A cautiously optimistic WHO official said ‘it can be good news, but we really require more studies to prove that’
- He warned Omicron’s high transmissibility means it will soon become dominant, posing a threat to medical systems in countries where many remain unvaccinated

More evidence is emerging that the Omicron coronavirus variant is affecting the upper respiratory tract, causing milder symptoms than previous variants and resulting in a “decoupling” in some places between soaring case numbers and low death rates, a World Health Organization official said on Tuesday.
“We are seeing more studies pointing out that Omicron is infecting the upper part of the body. Unlike other ones, the lungs who would be causing severe pneumonia,” WHO Incident Manager Abdi Mahamud told Geneva-based journalists.
“It can be good news, but we really require more studies to prove that.”
Since the heavily mutated variant was first detected in November, WHO data shows it has spread quickly and emerged in at least 128 countries, presenting dilemmas for many nations and people seeking to reboot their economies and lives after nearly two years of Covid-related disruptions.
However, while case numbers have surged to all-time records, the hospitalisation and death rates are often lower than at other phases in the pandemic.
“What we are seeing now is … the decoupling between the cases and the deaths,” he said.
His remarks on the reduced risks of severe disease chime with other data, including a study from South Africa, which was one of the first countries where Omicron was detected.
