New studies suggest that African countries rated as the least vulnerable to epidemics were most affected by COVID-19.

According to the survey, countries with large urban populations and strong ties to overseas travel were most affected by the pandemic.

Mortality and restriction levels (such as blockages and travel bans) have been found to be the lowest in countries previously considered to be at the highest risk of COVID-19.

A team of researchers at the University of Edinburgh’s NIHR Global Health Research Unit Working on Infections to Benefit Africa (TIBA) worked with the World Health Organization (WHO) Africa region to identify influencing factors. Mortality Between the first two COVID-19 waves in Africa and the timing of the first reported case.

TIBA Director Professor Mark Woolhouse, who co-led the study, said: “Our study shows very clearly that multiple factors affect the extent to which African countries are affected by COVID-19.

“Our results are at a high level Preparation Low resilience.

“Africa is not the only country where resilient, ready-to-wear countries have fallen into the worst of the pandemic. The result is that more developed countries have been hit particularly hard by COVID-19. Consistent with global trends. “

Of the 44 countries in the WHO Africa region for which data are available, South Africa had the highest mortality rate in the first wave from May to August 2020, with 33.3 deaths per 100,000. Cape Verde and Eswatini had the second highest mortality rates of 17.5 and 8.6 per 100,000, respectively. 0.26 deaths per 100,000 were recorded, with the lowest mortality rate in Uganda.

South Africa also recorded the highest mortality rate of 55.4 per 100,000 during the second wave from December 2020 to February 2021. Eswatini and Botswana recorded mortality rates of 39.8 and 17.7 per 100,000, respectively. The lowest rate was Mauritius, with no deaths recorded during the second wave.

“The early model that predicted that COVID-19 would lead to a huge number of cases in Africa was primarily the work of our non-continental institutions. This collaboration between African and European researchers is Africa. It emphasizes the importance of firmly fixing the analysis of the epidemic here. ” Dr. Machidiso Moetti, WHO Africa Regional Director and co-author. “It is no longer possible to focus our understanding of the transmission of the disease solely on the characteristics of the virus. COVID-19 works in a social context that has a significant impact on its spread.”

Like the big ones Urban population In addition, countries with high HIV prevalence are more likely to have higher mortality rates due to their strong international travel ties. The team suggests that this may be because people infected with HIV often have other health conditions that increase their risk of COVID-19.

The weak link between mortality and the timing or severity of restrictions on day-to-day activities imposed by the government indicates the impact of widespread application and enforcement of these restrictions throughout the region, identifying consistent patterns of impact. I’m making it difficult. Peak limits of infection are well documented to have prevented infection in the area.

Findings show that the earliest recorded cases of COVID-19 were countries where most people lived in urban areas and had strong international travel links and greater testing capabilities. .. Algeria first reported cases on February 25, 2020 in 47 African countries. Most countries recorded cases by late March 2020, and Lesotho last reported cases on May 14, 2020.

Researchers have recorded higher deaths during the second wave compared to the first wave. The peak of second wave infection was also high, with 675 deaths across the continent on January 18, 2021, compared to 323 at the peak of the first wave on August 5, 2020. The analysis considered the possibility of underreporting.

Dr. Sarah Puddicombe, Assistant Director of Global Health Research at NIHR, said: The WHO Regional Office has then created a regional, national, and pan-African response to the COVID-19 pandemic. “

Studies published in the journal Nature medicineWas supported by the National Institute of Health in the United Kingdom and the Darwin Trust in Edinburgh. Researchers from the University of Nairobi, the University of Ghana, and the University of Hong Kong also participated.
