AFRICA’S sharp increase in diabetes is clashing with the Covid-19 pandemic and poor access to vaccines. Africa’s death rates from Covid-19 infections are significantly higher in patients with diabetes, according to a preliminary analysis which the World Health Organisation (WHO) presented Thursday in advance of the World Diabetes Day on November 14.
‘Covid-19 is delivering a clear message: fighting the diabetes epidemic in Africa is in many ways as critical as the battle against the current pandemic,’ said Dr Matshidiso Moeti, WHO Regional Director for Africa.
‘The Covid-19 pandemic will eventually subside, but Africa is projected in the coming years to experience the highest increase in diabetes globally. We must act now to prevent new cases, vaccinate people who have this condition and, equally importantly, identify and support the millions of Africans unaware they are suffering from this silent killer,’ she said.
Diabetes impairs the body’s ability to produce or process insulin, a substance essential to counteracting a dangerous rise in blood sugar. The disease causes inflammation and poor blood circulation, both of which increase the risk of complications, including death, from Covid-19.
A recent WHO analysis evaluated data from 13 countries on underlying conditions or comorbidities in Africans who tested positive for Covid-19. It revealed a 10.2 percent case fatality rate in patients with diabetes, compared with 2.5 percent for Covid-19 patients overall.
The case fatality rate for people with diabetes was also twice as high as the fatality rate among patients suffering any comorbidity. In addition to people with diabetes, the three most frequent underlying conditions included patients with HIV and hypertension.
The countries contributing data to the analysis were Burkina Faso, Chad, Cote d’Ivoire, Democratic Republic of the Congo, Eswatini, Guinea, Namibia, Niger, Rwanda, Senegal, Seychelles, Sao Tome and Principe and Uganda.
An estimated 24 million people are living with diabetes in Africa in 2021 according to the International Diabetes Federation and the continent is expected to experience the highest increase in diabetes globally, with the number of Africans suffering from the disease predicted to rise to 55 million by 2045, an increase of 134% compared with 2021. Africa is the region with the highest number of people who do not know their diagnosis – an estimated 70 percent of people with diabetes do not know they have the disease.
‘Health officials in Africa should take advantage of the growing availability of low-cost rapid diagnostic tests to routinely test patients in diabetes centres to ensure early detection and proper care,’ said Dr Benido Impouma, Director, Communicable and Noncommunicable Diseases Cluster at WHO Regional Office for Africa. ‘These centres also can be key venues for vaccination.’
Since the early days of the pandemic, people with diabetes in countries around the world have been prioritised to receive Covid-19 vaccinations. Africa has faced challenges in this strategy.
Access to vaccines remains poor. Thus far, only 6.6 percent of the African population is fully vaccinated against Covid-19, compared with about 40 percent globally. Data from 37 countries indicates that since March 2021, over 6.5 million Covid-19 vaccine doses have gone to Africans with comorbidities, representing 14 percent of all doses administered so far. Efforts to prioritize people with comorbidities, like diabetes, are accelerating with about half of those 6.5 million doses administered in just the last couple of months. However, there is still a lot more work to be done to ensure people at high risk receive the vaccines they need.
‘Nine months since Covid-19 vaccination campaigns began in Africa, we are still nowhere near where we need to be with protecting our most vulnerable,’ Dr Moeti said. ‘There is an urgent need to step up vaccination and other key services to people at high risk, including those with diabetes.’
During the Covid-19 pandemic, access to diabetes care has been severely disrupted in the African Region. Lockdowns to limit the spread of Covid-19, for example, have impeded access to health care and the basic elements of proper disease management, such as routine glucose monitoring and eating a healthy diet.
