COVID-19: The virus could infect more than 200 mn in Africa: WHO modeling. The new coronavirus could kill 150,000 people in Africa in a year unless urgent action is taken

according to a WHO modeling study that says nearly a quarter of a billion people will be infected. But while they said many African nations had been swift to adopt containment measures, they warned that health systems could still quickly become overwhelmed. Experts at the World Health Organization’s Africa office modeled likely rates of exposure to the virus and infection in the 47 countries under its regional remit, which excludes Djibouti, Egypt, Libya, Morocco, Somalia, Sudan, and Tunisia.
“The region will have fewer deaths, but occurring more in relatively younger age groups, amongst people previously considered healthy –- due to undiagnosed non-communicable diseases,” the report said, adding that these trends were already emerging. They also included the weather. It is not known if warmer temperatures slow down the spread of COVID-19, though some research has suggested it has that effect on other coronaviruses.
Authors of the research, published Friday in the journal BMJ Global Health, predicted a lower infection rate than in other parts of the world like Europe and the US, with fewer severe cases and deaths.
“Our model points to the scale of the problem for health systems if containment measures fail,” said the authors.
Some 231 million people or 22 percent (with a range of 16 to 26 percent) of the one billion people in the region were expected to be infected in the 12 month period — most of them showing few or no symptoms. The researchers said they expect the virus would likely circulate within the region for longer than other countries, possibly for several years. Researchers factored in each country’s measures to control the spread of the virus, including physical distancing.
The study comes amid stark warnings that COVID-19 threatens a health emergency in developing nations where fragile health systems are already struggling with an array of other chronic diseases.
But an estimated 4.6 million people would need to be admitted to hospital, while 140,000 would have severe COVID-19 infection and 89,000 would be critically ill.
The modeling estimates what would happen for each country over the period of a year from the beginning of widespread and sustained community transmission.
