The World Health Organisation (WHO) has warned that Africa is facing a fast-surging third wave of COVID-19 pandemic, with cases spreading more rapidly and projected to soon overtake the peak of the second wave the continent witnessed at the start of 2021.
The Geneva-based organisation explained that COVID-19 cases have risen for five consecutive weeks since the onset of the third wave on 3 May 2021.
Providing data as of June 20—day 48 into the new wave—Africa had recorded around 474 000 new cases—a 21 per cent increase compared with the first 48 days of the second wave. At the current rate of infections, the ongoing surge is set to surpass the previous one by early July.
A combination of factors including weak observance of public health measures, increased social interaction and movement as well as the spread of variants are powering the resurging in 12 African countries.
In the Democratic Republic of the Congo and Uganda that are experiencing COVID-19 resurgence, the Delta variant has been detected in most samples sequenced in the past month. Across Africa, the variant—first identified in India—has been reported in 14 countries.
Speaking on this, Dr Matshidiso Moeti, WHO Regional Director for Africa, “The third wave is picking up speed, spreading faster, hitting harder. With rapidly rising case numbers and increasing reports of serious illness, the latest surge threatens to be Africa’s worst yet.
“Africa can still blunt the impact of these fast-rising infections, but the window of opportunity is closing. Everyone everywhere can do their bit by taking precautions to prevent transmission.”
WHO is deploying more experts to some of the worst-affected countries, including Uganda and Zambia as well as supporting South Africa-based regional laboratories to monitor variants of concern.
WHO is also boosting innovative technological support to other laboratories in the region without sequencing capacities to better monitor the evolution of the virus. In the next six months, WHO is aiming for an eight- to ten-fold increase in the samples sequenced each month in Southern African countries.
The COVID-19 upsurge comes as the vaccine supply crunch persists. Eighteen African countries have used over 80 per cent of their COVAX vaccine supplies, with eight having exhausted their stocks. Twenty-nine countries have administered over 50 per cent of their supplies.
Despite the progress, just over 1 per cent of Africa’s population has been fully vaccinated. Globally, around 2.7 billion doses administered, of which just under 1.5 per cent have been administered in the continent.
As many high-income countries vaccinate a significant proportion of their populations, proof of vaccination is leading to fewer movement restrictions.
Globally, 16 countries are waiving quarantine for those with a vaccination certificate. Measures to prevent COVID-19 transmission are crucial, but with many African countries having limited access to vaccines, it is important that vaccines be only one of the conditions countries use to open borders and increase freedom of movement.
“With high vaccination rates, it’s shaping up into a summer of freedom, family and fun for millions of people in richer countries. This is understandable and we all long for the same joys,” said Dr Moeti.
“Vaccine shortages are already prolonging the pain of COVID-19 in Africa. Let’s not add injury to injustice. Africans must not face more restrictions because they are unable to access vaccines that are only available elsewhere. I urge all regional and national regulatory agencies to recognize all the vaccines Emergency Use listed by WHO,” she added.
In the European Union, a COVID-19 passport system for vaccination, testing and recovery will take effect from July 1. However, only four of the eight vaccines listed by WHO for emergency use are recognized by the European Medicines Agency (EMA) for the passport system.
WHO and the European Medicines Agency use the same standards in assessing vaccines. Manufacturers may choose not to apply to the European Medicines Agency if they do not intend to market their products in countries in the European Union or European Economic Area. But the safety and efficacy of all WHO emergency use listed vaccines have been proven globally in preventing severe COVID-19 illness and death.
In Africa, a WHO survey of 45 countries shows that their borders are open for air travel and only Mauritius will require proof of vaccination for international travellers from 15 July 2021. Most countries do not give quarantine exemptions for travellers who are fully vaccinated against COVID-19 and require a negative COVID-19 test.
