Coronavirus Update: Pandemic is still a public health emergency, warns WHO, urging greater surveillance including testing and sequencing


The World Health Organization said Tuesday the coronavirus pandemic remains a public health emergency, and warned that a reduction in surveillance, including testing and sequencing, is making it difficult to assess the impact of new variants.

“The virus is running freely and countries are not effectively managing the disease burden based on their capacity, in terms of both hospitalization for acute cases and the expanding number of people with post-COVID-19 condition — often referred to as long COVID,” WHO Director General Tedros Adhanom Ghebreyesus said at a Geneva news briefing.

The agency’s Emergency Committee unanimously agreed at a Friday meeting that the pandemic continues to adversely impact the health of the world’s population, and that the emergence — and rapid spread — of new variants may present an ever greater health impact.

“The epidemiology of SARS-CoV-2 virus infection remains unpredictable as the virus continues to evolve, through sustained transmission in the human population and in domestic, farmed, and wild animals in which the virus was newly introduced,” the committee said in a statement published Wednesday.

The statement highlighted that the public perception that the pandemic may be over is a concern and urged political leaders to help shift that risk perception with more consistent messaging, particularly to those communities currently experiencing high levels of transmission.

The news comes as the daily average for new U.S. cases stood at 129,858 on Tuesday, according to a New York Times tracker, up 19% from two weeks ago.

The daily average for hospitalizations rose to 38,517 on Tuesday, up 18% in two weeks. And the positivity rate on COVID tests stands at 18%, the highest since Feb. 1. The daily average for deaths is up 5% to 396. 

In the U.K., meanwhile, the new omicron subvariant BA.2.75, which is spreading rapidly in India and has shown up in the U.S., Australia, Germany and Canada, has been dubbed ‘Centaurus”, the Guardian reported. The new variant is understood to be spreading faster than the BA.5 variant.

The WHO is monitoring the variant, but for now there’s too little data to know whether it is more severe than earlier ones.
