Severe disease due to Omicron in unvaccinated, 50 per cent of Europe may soon get infected: WHO European Regional Director

World Health Organisation (WHO) European Regional Director, Hans Kluge has warned that the Omicron variant could become more prevalent in Europe as the "tidal wave" of infections spreads eastward. "I am also deeply concerned that as the variant moves east. We are yet to see its full impact in countries where levels of vaccination uptake are lower. We will see more severe disease in the unvaccinated," said Kluge on Tuesday. 

Although, the WHO official urged the schools to remain open. "Keeping schools open benefits children's mental, social and educational well-being significantly. School buildings should be the last to close and the first to reopen," Kluge said.

According to him, the Omicron variant, now spreading into the Balkans, is already present in 50 of the 53 countries in the region spanning Europe and Central Asia. "At this rate, the Institute for Health Metrics and Evaluation (IHME) forecasts that more than 50 per cent of the population in the region will be infected with Omicron in the next 6 to 8 weeks," he added. 

Kluge said the hospitalisations were rising due to the unprecedented scale of transmissions in the region. To better manage the Coronavirus's destructive impact on health services, economies and societies, the WHO official called for practical actions, including acting immediately and planning for contingencies, and prioritising response systems during the "closing window of opportunity".

He also emphasised the importance of protecting the vulnerable and "minimising disruption to health systems and essential services". Additionally, he outlined his five pandemic stabilising rules: vaccination, third doses or boosters, increased mask use, ventilation of crowded or enclosed spaces and the continued use of new clinical protocols to guide the response to Delta or Omicron.

The WHO Europe also said it's "way off" from treating the COVID-19 as endemic. "We're still a way off. Endemicity assumes, first of all, a stable circulation of the virus at predictable levels and potentially known and predictable waves of epidemic transmission," said Catherine Smallwood, Senior Emergency Services Officer at WHO Europe, when asked about an opinion on Spain's recent request to the European Union to discuss the possibility of COVID-19 being classified as an endemic illness, similar to the flu or malaria, which is always present in a particular population or region.

"What we're seeing at the moment coming into 2022 is nowhere near that... We still have a virus that's evolving quite quickly and posing quite new challenges... and there's still a lot of unpredictability, " she added.
