Deadly Omicron should not be called mild, warns WHO

Recent studies suggest that Omicron is less likely to make people seriously ill than previous Covid variants.

But the record number of people catching it has left health systems under severe pressure, said WHO chief Dr Tedros Adhanom Ghebreyesus.

On Monday, the US recorded more than one million Covid cases in 24 hours.

The WHO - the UN's health agency - said the number of global cases has increased by 71% in the last week, and in the Americas by 100%. It said that among severe cases worldwide, 90% were unvaccinated.

WHO chief optimistic Covid will be beaten in 2022

Dr Tedros Adhanom Ghebreyesu warned against "narrow nationalism and vaccine hoarding" in a new year statement.

His comments come two years since the WHO was first notified of cases of an unknown pneumonia strain in China.

Global Covid cases now stand at 287m, while nearly 5.5m people have died.

Across the world people are marking the new year but celebrations are muted, with many countries wanting to discourage crowds gathering.

Omicron probably in most countries, WHO says

Cases of the heavily mutated variant have been confirmed in 77 countries.

But WHO chief Tedros Adhanom Ghebreyesus said it was probably in many others that had yet to detect it, and was spreading at an unprecedented rate.

Dr Tedros said he was concerned that Omicron was being underestimated.

"Surely, we have learned by now that we underestimate this virus at our peril. Even if Omicron does cause less severe disease, the sheer number of cases could once again overwhelm unprepared health systems," he said.

WHO public health expert on the risk of Omicron

As more countries around the world report cases of Omicron, much remains unknown about the new Covid-19 variant.

It is less than two weeks since Omicron was designated a "variant of concern" by the World Health Organisation, after it was first reported by scientists in South Africa.

Covid: WHO urges those at risk from disease to delay travel over Omicron

In its latest travel advisory, the UN agency includes in that category people over 60, and those with conditions such as heart disease, cancer and diabetes.

It also restates its position that blanket travel bans do not prevent the spread of the variant.

South Africa alerted the world about the variant last week.

Many countries then proceeded to impose restrictions on travel from countries in southern Africa.

"Blanket travel bans will not prevent the international spread, and they place a heavy burden on lives and livelihoods," the WHO said in its statement.

Omicron: WHO warns of 'high infection risk' around globe

The variant could lead to severe consequences in some regions, the WHO said on Monday.

The head of the organisation, Dr Tedros Adhanom Ghebreyesus, renewed a call for a global push to get vaccines to poorer nations.

Covid-19 is "not done with us" yet he warned.

The variant was detected in South Africa earlier this month with initial evidence suggesting it has a higher re-infection risk. South Africa has been praised for its prompt reporting of the variant.

WHO labels new Covid strain, named omicron

The U.N. health agency recognized the strain, first referred to as lineage B.1.1.529, as a variant of concern.

Health experts are deeply concerned about the transmissibility of the omicron variant given that it has an unusual constellation of mutations and a profile that is different from other variants of concern.

Covid virus may have killed 80k-180k health workers, WHO says

Healthcare workers must be prioritised for vaccines, WHO head Tedros Adhanom Ghebreyesus said, and he criticised unfairness in the distribution of jabs.

The deaths occurred between January 2020 and May of this year.

Earlier, another senior WHO official warned a lack of jabs could see the pandemic continue well into next year.

There are an estimated 135 million healthcare workers globally.

"Data from 119 countries suggest that on average, two in five healthcare workers globally are fully vaccinated," Dr Tedros said.

New WHO group may be last chance to find virus origins

It has nominated 26 experts to join the body, the Scientific Advisory Group on the Origins of Novel Pathogens (Sago).

More than a year-and-a-half since the virus was detected in the Chinese city of Wuhan, the question of how it first emerged remains unclear.

The team will consider if the virus jumped from animals to humans in Wuhan markets or leaked in a lab accident.

China has strongly refuted the second theory.

WHO renames UK and other variants with Greek letters

From now on the WHO will use Greek letters to refer to variants first detected in countries like the UK, South Africa and India.

The UK variant for instance is labelled as Alpha, the South African Beta, and the Indian as Delta.

The WHO said this was to simplify discussions but also to help remove some stigma from the names.

Earlier this month the Indian government criticised the naming of variant B.1.617.2 - first detected in the country last October - as the "Indian variant", though the WHO had never officially labelled it as such.
