Seriously ill Covid-19 patients in African countries are more likely to die than those on other continents, which could be because of a lack of critical care equipment, a study published Friday said. Authors suggest the mortality rate of those who do get sick could be even higher than their figures suggest because of a lack of data. AFP reports that the study followed 3,000 coronavirus patients admitted to intensive care units across 10 African countries between May and December last year. Almost half of them died within 30 days of admission.
