The last two weeks has seen more COVID-19 cases worldwide, than the first six months of the pandemic.
According to the WHO Director-General Tedros Adhanom Ghebreyesus on Monday, India and Brazil accounted for more than half of last weeks' cases, but there are many other countries across the globe facing "a very fragile situation".
The UN health agency is providing equipment and supplies, including oxygen concentrators to India, while the WHO Foundation is also raising funds to support the need for oxygen and related supplies worldwide.
And the situation continues to be dire in India due to the lack of oxygen supplies,. as more and more patients in the country are dying daily due to a collapse in the medical system.
According to media reports, 24 people have died at a hospital in India's southern state in the span of 24 hours, due to the oxygen shortage.
However, health officials say, while there had been issues with oxygen supplies, not all deaths were due to the oxygen shortage, and added investigations were ongoing.
India continues to see its country ravaged by the second wave of the outbreak, reporting over 368-thousand cases on Monday.
Meanwhile over in the United States, despite more than half of the adults in the country having been vaccinated with at least one dose, daily vaccination rates are slipping.
According public health experts, the herd immunity threshold is currently not attainable, at least not in the foreseeable future, or perhaps not ever.
They added that instead, the virus will most likely become a manageable threat that will continue to spread for years to come, still causing hospitalizations and deaths, but in much smaller numbers.
One thing's for sure, the virus is mutating too quickly, and new variants are spreading faster than the vaccination process, making herd immunity unlikely anytime soon.
