GENEVA, Switzerland (AFP) — It is unrealistic to think that the world will be done with the COVID-19 pandemic by the end of the year, the WHO said Monday.

The World Health Organization's emergencies director Michael Ryan said it might be possible to take the sting of tragedy out of the coronavirus crisis by reducing hospitalisations and deaths.

But the virus remains very much in control, he added, especially given that global new case numbers increased this week after seven consecutive weeks of decline.

"It will be very premature and I think unrealistic to think that we're going to finish with this virus by the end of the year," Ryan told journalists.

"But I think what we can finish with, if we're smart, is the hospitalisations, the deaths and the tragedy associated with this pandemic."

Ryan said the WHO's focus was on keeping virus transmission low, to help prevent the emergence of variants, but also to reduce the numbers of people who get sick.

He also said vaccinating front-line health care workers and those most vulnerable to severe disease would "take the fear and the tragedy out of the pandemic".

WHO director-general Tedros Adhanom Ghebreyesus wants the vaccination of health care workers under way in every country within the first 100 days of 2021 — meaning there are 40 days left to go.

He welcomed the first injections of doses through the global Covax vaccine-sharing facility, which were administered Monday in Ghana and the Ivory Coast.

"It's encouraging to see health workers in lower-income countries starting to be vaccinated, but it's regrettable that this comes almost three months after some of the wealthiest countries started their vaccination campaigns," he said.

"And it's regrettable that some countries continue to prioritise vaccinating younger, healthier adults at lower risk of disease in their own populations ahead of health workers and older people elsewhere," he said, without naming them.
