Coronavirus cases set to hit 10 million mark worldwide: WHO chief.

The World Health Organization (WHO) chief, Tedros Adhanom Ghebreyesus, has said he expected the number of coronavirus cases around the world, now at about 9.1 million, to reach 10 million next week.

Tedros also told a virtual news briefing in Geneva he backed Saudi Arabia's decision to ban pilgrims from abroad from attending the annual Hajj pilgrimage to help limit the spread of the deadly disease.

He said WHO was now supporting many countries in dealing with difficulties obtaining oxygen concentrators, devices that boost the flow of oxygen to support the breathing of COVID-19 sufferers. "Demand is outstripping supply," he said.

Tedros said that more than 9.1 million cases of COVID-19 have been reported so far and more than 470,000 deaths. In the last month, almost 4 million have emerged.

By contrast, he said less than 10,000 cases were reported in the first month of the outbreak.

Providing oxygen to those who need it is one of the most effective ways to save lives, he said. This has been area of intense focus for WHO since the beginning of the outbreak, as patients in severe and critical condition cannot bring enough of it into their bloodstreams, by breathing normally. They need higher concentrations and support.

Left untreated, severe COVID-19 deprives cells and organs of oxygen, Tedros explained, leading to organ failure and death.

Medical oxygen is created by using concentrators which extract and purify oxygen from the air. At the current rate of one million new cases each week, the world needs 620,000 cubic metres of oxygen daily, he said, the equivalent of 88,000 large cylinders.

However, the WHO chief and former health minister of Ethiopia said many countries are finding it difficult to obtain concentrators, as 80 per cent of the market is owned by just a few companies. Demand is outstripping supply.

To ease shortages, WHO is buying them for countries that need them most, he said, and ongoing talks with suppliers have led to the purchase of 14,000 concentrators, which WHO will send to 120 countries in the coming weeks...
