The World Health Organisation (WHO) said it is unlikely the Covid-19 pandemic will come to an end by the end of 2021.
“I think it will be very premature and unrealistic to think that we are going to finish with this virus by the end of the year,” Michael Ryan, director of the WHO’s health emergencies programme, said at a briefing on Tuesday.
“What we can, if we are smart, finish with is the hospitalisations and the deaths and the tragedy associated with this pandemic,” Ryan added.
The WHO’s focus at present was to keep transmissions as low as possible and vaccinate more and more people.
The situation regarding the delivery of vaccine doses had already improved compared to 10 weeks ago, Ryan said, although there were “huge challenges” in distributing them and the virus still had the upper hand.
“If the vaccines begin to impact not only on death and not only on hospitalisation, but have a significant impact on transmission dynamics and transmission risk, then I believe we will accelerate towards controlling this pandemic,” Ryan said.
The number of new cases of COVID-19 rose by 7 per cent worldwide, last week, the WHO said later on Tuesday.
This is the first increase following a fall in case numbers over the past six weeks.
In the last week of February, 2.6 million cases were reported to the UN agency in Geneva in the last week of February.
The increase could be due to new and more contagious strains of the virus, the WHO said, citing easing of rules and fatigue with regulations as other possible causes.
The Middle East saw the largest rise of 14 per cent, followed by a 9-per-cent rise in South-East Asia. Case numbers also rose by 9 per cent in Europe and by 6 per cent in the Americas.
In contrast, nearly a quarter fewer cases were reported in Africa compared to the week before.
Likewise case numbers fell slightly in the Western Pacific region including East Asia and Australia.
According to WHO， vaccines do not provide immunity immediately but need several weeks before they become effective, and noted it would take even longer to protect whole populations.
That means testing, contact tracing, social distancing, masks and other hygiene measures remain critical.
