Media BGR reported that, with the exception of Africa, the spread of the new coronavirus around the world is still very high. The situation in Africa is better than on any other continent, with fewer confirmed cases and fewer deaths. Scientists can’t explain why the region didn’t erupt on a large scale like other continents, but they have a theory that might explain the evolution of the new coronavirus outbreak.
Scientists believe that previously infected human coronavirus, which causes the common cold, may provide additional COVID-19 protection for people in African countries compared to other countries. But this hypothesis has yet to be tested by scientific data.
The assumption that poverty may have a significant impact on the spread of the virus does not hold true throughout the African continent. Developing countries such as Brazil and India have shown that the new coronavirus cannot be controlled once it reaches densely populated but poor communities. Experts expect the same thing to happen in Africa, but that is not the case. If anything, Africa does better than other continents, both in cases and in casualties. As BBC News explains, even if these figures are grossly underestimated, The situation in Africa is still much better than on other continents.
“I thought we were heading for a disaster, a complete collapse,” Professor Shabir Madhi, South Africa’s top virologist, told BBC News. The scientist agreed with others’ positive thoughts about the outbreak of the new coronavirus in Africa. But South Africa’s mortality rate is almost one-third that of Britain. “Most African countries don’t have peaks,” Salim Abdool Karim, head of the country’s COVID-19 response team, told the BBC. I don’t understand why. I don’t understand at all. He added.
He explained that factors such as population density would be key factors contributing to the rapid spread of the disease within the continent. Congestion in poor areas makes it almost impossible to maintain social distance, which increases the risk of COVID-19 transmission. One hypothesis that explains the gap between Africa and other continents is the overall age of the population. In general, Africa’s population is younger than that of the areas most affected by COVID-19.
Another hypothesis sounds familiar to those who have been keeping a close eye on the development of the new coronavirus. Some researchers have shown that other human coronavirus, which causes the common cold, can cause an immune response that provides protection against COVID-19. Researchers in South Africa set out to study the idea, trying to analyze five-year-old blood samples from Sovito’s flu vaccine trial. Their plan is to look for any evidence to explain why the continent is better able to fight the disease than any other country. The samples were damaged by technical problems, which halted the study.
But the idea still exists. Similarly crowded communities can lead to the rapid spread of other coronavirus, which may have protected the population from SARS-CoV-2. “It’s a hypothesis. Some degree of pre-existing cross-protective immunity… It may explain why the epidemic is not unfolding, as it is in other parts of the world,” Mahdi said. “In densely populated areas, in the African environment, this protection is likely to be stronger, ” he says. This may explain why most people (on the African continent) do not have symptoms or mild infections. “
“I can’t think of anything else to explain the number of completely asymptomatic people we see. These numbers are completely incredible,” he said.
But if that assumption is true, why have Brazil and India seen a massive surge in COVID-19s in the past few months? Karim warns that Africa is not out of the woods, even given the evolution of the continent’s outbreak to date. “I’m not sure one day the outbreak will go crazy here, ” he says. “
