• Saving lives from COVID-19 will be of little benefit if deaths from HIV, TB and malaria continue to rise in Africa, write Winnie Byanyima, Lucica Ditiu and Abdourahame Diallo.
  • They argue that policymakers across the continent should not lose sight of tackling other health crises and warn of dire consequences if they do.

As the number of confirmed COVID-19 cases in Africa surpasses 500,000, the new coronavirus is at the forefront of the public consciousness. But the continent was beset by infectious disease long before the current pandemic began. And, as long as governments and donors remain preoccupied with curbing COVID-19, killers like HIV/AIDS, malaria, and tuberculosis (TB) will only grow stronger.

Of 38 million people worldwide living with HIV, the virus that causes AIDS, 25.6 million reside in Sub-Saharan Africa. Africa accounted for 380,000 malaria deaths – 94% of the global total – in 2018. And, 2.6 million people in Africa develop TB every year, resulting in 630,000 deaths.

Over the last two decades, considerable progress has been made in fighting these diseases. AIDS-related deaths have been reduced by more than half since 2004, thanks largely to the availability of antiretroviral therapy. The TB mortality rate fell by 42% between 2000 and 2017. And malaria deaths decreased by 60% between 2000 and 2015; a child who contracts malaria today has a better chance of survival than ever before.

But the COVID-19 crisis threatens to stall or even reverse this progress, not least by inundating already-fragile health systems. Italy has one doctor for every 243 residents and yet, in some regions, its health system buckled under the weight of COVID-19 cases. Imagine what a similar outbreak would do in African countries, which have an average of one doctor for every 5,000 residents.

To be sure, the coronavirus has spread more slowly in Africa than in Europe and North America. But the World Health Organization warns that the outbreak could be stretched out over a few years. If so, the continent’s under-resourced health systems will be under severe strain for a long time to come. And what resources governments do have are likely to be channeled toward COVID-19 – even if it means redirecting them from other deadly diseases.

Supply-chain disruptions caused by containment measures elsewhere compound the risks, by threatening access to the preventive-health resources, diagnostics, and treatments needed to combat HIV, TB, and malaria. Already, some African countries have paused programs providing TB and HIV treatments and diagnostics, and suspended distribution of insecticide-treated mosquito nets (ITNs) – essential to protect against malaria – right before the high-transmission rainy season.

The WHO forecasts that under the worst-case scenario (suspension of all ITN campaigns and a 75% reduction in access to effective antimalarial drugs), the COVID-19 crisis could lead to a doubling of malaria deaths this year in Sub-Saharan Africa. Such high malaria mortality levels were last recorded 20 years ago.

Moreover, a six-month disruption of antiretroviral therapy could lead to more than 500,000 additional deaths from AIDS-related illnesses (including TB) in Sub-Saharan Africa in 2020-21. In 2019, an estimated 440,000 people died of AIDS-related illnesses in the region.

Likewise, a study led by the Stop TB Partnership shows that a three-month lockdown and ten-month recovery period could lead to an additional 1.4 million TB deaths globally between 2020 and 2025. In this scenario, the global fight against TB would be set back by 5-8 years.

Such outcomes are not inevitable. What is needed is a global collective response focused on delivering life-saving services, reducing the burden on already overstretched health systems, and protecting Africa’s most vulnerable. Success will depend on innovative solutions, a holistic perspective (rather than disjointed single-disease programs), and an equity-first approach.

For starters, diagnostic tests – for COVID-19 and many other common diseases – must be accessible to all – and especially to high-risk populations. Africa has well-established testing services for several common diseases, including multi-disease testing for HIV and TB. But these programs are now at risk, and Africa is also falling behind other regions in testing for COVID-19.

But there is promising news: some countries have introduced joint testing for TB and COVID-19 and for malaria and COVID-19 (and immediate malaria treatment if required). Joint testing makes all the more sense, because HIV, TB, and malaria may all cause symptoms consistent with COVID-19, such as high fevers. Such programs must be scaled up, so that diagnostics and treatments – which are often expensive and difficult to access – are available to all.

This is entirely achievable. African countries, which have plenty of experience with health emergencies, have responded quickly and effectively to the threat of COVID-19. The African Union, through the Africa Centers for Disease Control and Prevention, is providing strong regional leadership to coordinate the response.
