The World Health Organisation on Thursday hinted that the weekly COVID-19 cases have declined by more than 20 percent in Africa.
The organisation disclosed this in a statement titled “COVID-19 variants prolong Africa’s pandemic wave.”
The statement read, “Weekly COVID-19 cases in Africa fell by more than 20%—the sharpest seven-day decline in two months – as the third wave pandemic tapers off.
“However, the rate of deceleration is slower than the previous waves owing to the impact of more transmissible variants.
“The continent recorded more than 165 000 cases in the week ending on 5 September—23% lower than the week before, yet still higher than the weekly cases recorded at the peak of the first wave.
“The more contagious Delta variant that partly fuelled the third wave has been dominant in several countries that experienced COVID-19 surge. In southern Africa, for instance, where more than 4000 COVID-19 genome sequencing data was produced in August, the Delta variant was detected in over 70% of samples from Botswana, Malawi, and South Africa, and in over 90% from Zimbabwe.”
Also quoted in the statement was the Africa regional Director for the WHO, Dr Matshidioso Moeti, who said the continent was working towards increasing the rate of genomic sequencing.
She said, “While COVID-19 cases have declined appreciably, the downward trend is frustratingly slow due to the lingering effects of the more infectious Delta variant.
“We are spearheading critical work and supporting countries in scaling up pathogen surveillance through genome sequencing to detect and respond effectively to COVID-19 variants.
“The continent lags far behind the rest of the world when it comes to sequencing, with only 1% of over 3 million COVID-19 sequences conducted worldwide occurring in Africa.
“The third wave has shown us how variants can hijack the efforts to tame the pandemic. Countries must step up surveillance because, without genomic information, variants can spread undetected. You can’t fix what you don’t measure.”
The statement added that the WHO had recently provided financial support to countries including Eswatini, Sao Tome and Principe and Senegal to reinforce genomic surveillance. To date, the dominant Delta variant has been detected in 31 African countries, while the Alpha and Beta variants have respectively been identified in 44 and 39 countries.
The C.1.2 variant initially identified in South Africa has so far been detected in 130 cases in 10 countries globally, including five in Africa. Although the variant has exhibited concerning mutations, there is no evidence that it is more transmissible or may affect vaccine efficacy, but more research is needed.
As Africa’s third COVID-19 pandemic wave eases off, vaccine shipments to the continent continue to grow, with around 5.5 million doses received through COVAX in the first week of September. However, only around 3% of the continent’s population is fully vaccinated.
“To ultimately tip the scales against this pandemic, our best efforts to reduce transmission through public health measures must be met by a significant step-up in vaccine supplies and vaccinations,” Moeti said.
