Although the Riyadh Digital Global Health Summit was told that mask wearing in the region is already high by global standards, modelling suggests as many as 1,000 extra deaths could be saved in Saudi Arabia alone this year.
Vast wealth and the promise of dramatic change make for cautious optimism concerning Saudi Arabia, the chief executive…152 Views | the publication reaches you by | Saudi Arabia Today
Addressing the conference remotely, Prof Ali Mokdad, a health metrics specialist at the University of Washington who focuses on the Middle East, said his forecasts suggested Saudi Arabia’s coronavirus death toll would reach about 5,800 by the beginning of December. Until now the Kingdom has registered around 3,200 deaths.
He highlighted the UAE, Oman and Saudi Arabia as countries where much of the population already wears masks, but said many lives could be saved if more people used face coverings.
“Right now mask-wearing is around 75 per cent [in Saudi Arabia], but 1,000 less deaths could be achieved if 95 per cent of people in Saudi Arabia wore masks,” he said.
“For Saudi Arabia, we’re showing how many beds they need. Saudi Arabia will not have a shortage of beds, will not have a shortage of ICUs [intensive care unit beds] or ventilators, because they have a strong medical system.”
Because infection rates in the country are forecast to remain relatively under control, a lockdown is unlikely to become necessary.
However, the conference heard the picture varied significantly across the Middle East, with the situation in Iran forecast to deteriorate dramatically as infection rates increase.
By the beginning of December, the number of deaths in the country is could exceed 71,000, almost four times the current total of just over 18,000.
“We expect it will go into a lockdown some time in October. In Iran we expect that there will be a shortage of beds some time in November in the peak of the second wave,” said Prof Mokdad.
“This wave is staying with us in a roller coaster. They will not have enough beds, they will not have enough ICUs compared to what we’re showing in Saudi Arabia.”
In the United States, where there is resistance among some to wearing masks, the death toll is forecast by Prof Mokdad to grow to about 295,000 by the beginning of December, almost twice what it is now – about 163,000.
However, if 95 per cent of people wore masks outside the home, 66,000 of the additional deaths could be avoided. This represents “a huge difference”, Prof Mokdad said.
Experts acknowledged that projections for death and infection rates are more difficult to make now than at the pandemic’s start, when the initial wave of cases was relatively easy to understand.
“The pandemic is much more unpredictable now,” said Dr Erik Volz, of the School of Public Health at Imperial College London.
“It depends on evolution [of the virus], political considerations, behavioural fatigue and a vaccine.
“We don’t know if we’ll have an effective vaccine and how quickly production can be ramped up. These are giant unknowns and we won’t have greater clarity until later this year.”
One positive he highlighted was that the quality of care for patients with Covid-19 has “improved dramatically” in recent months, especially in developed countries. Drugs such as the antiviral medicine remdesivir are a key reason for higher survival rates.
