Sharing information is vital to tackling the pandemic in Africa – both for planning the response and mobilising donor funding – public health experts say. As things stand, it is impossible to gauge the full severity of the contagion across the continent.

According to the latest data collated by Reuters, Africa, with a population of 1.3 billion people, had over 493,000 confirmed cases and 11,600 deaths. By comparison, Latin America, with roughly half the population, had 2.9 million cases and 129,900 deaths.

The official numbers make it seem as though the illness has skirted much of Africa, but the real picture is certain to be worse, with WHO special envoy Samba Sow warning on May 25 of a possible “silent epidemic” if testing was not prioritised.

By July 7, 4,200 tests per million people had been carried out across the continent, according to a Reuters analysis of figures from the Africa Centres for Disease Control and Prevention (CDC), a body set up by the African Union in 2017. That compares with averages of 7,650 in Asia and 74,255 in Europe.

Interviews with dozens of health workers, diplomats and local officials revealed not just a scarcity of reliable testing in most countries, but also the lengths some governments have gone to prevent news of infection rates from emerging, even if that meant they missed out on donor funding.

“We cannot help a country against its own will,” Michel Yao, head of emergency operations for the WHO in Africa, told Reuters. “In some countries, they are having meetings and not inviting us. We are supposed to be the main technical advisor.”  Yao declined to single out countries, saying the WHO needed to preserve a working relationship with governments.

Tanzania confirmed its first case of COVID-19 on March 16. The next day, the government convened a task force  to coordinate the response with international partners including the WHO, foreign embassies, donors and aid agencies, multiple sources said.

This body never met again with outsiders, two foreign officials familiar with the situation told Reuters, while government officials failed to show up to dozens of subsequent coronavirus-related meetings, they said.

“It’s very clear the government does not want any information about the state of COVID in the country,” said one aid official, who like many of those interviewed by Reuters for this story, asked not to be identified for fear of antagonizing political leaders.

Tanzania’s health minister Ummy Mwalimu and government spokesman did not respond to phone calls or emailed questions raised by this article about their handling of the crisis. The spokesman, Hassan Abbasi, has previously denied withholding information about the country’s epidemic.

Tanzania has not published nationwide figures since May 8, when it had recorded 509 cases and 21 deaths. Days earlier, President Magufuli dismissed testing kits imported from abroad as faulty, saying on national television that they had also returned positive results on samples taken from a goat and a pawpaw fruit.

According to three emails seen between May 8-13, the WHO believed it had reached an agreement with the government to let it take part in joint surveillance missions around the country. However, a WHO spokeswoman said these were all cancelled on the day they were supposed to start, with no reason given.

Donors have released some $40 million to fund Tanzania’s coronavirus response, two diplomatic sources involved said. But the country’s lack of engagement meant it had missed out on “tens of millions of dollars” more, another official said.

By mid-May, the government decided to ease its lockdown, despite doctors and diplomats saying the outbreak was far from contained. The U.S. Embassy warned its citizens on May 13 that hospitals in the main city Dar es Salaam were “overwhelmed”, an assertion denied at the time by the Tanzanian government.

Tanzania’s failure to share information about its outbreak has frustrated its neighbours, who fear that gains won through painful lockdowns in their own countries could be jeopardized as Tanzanians cross porous borders.

The WHO organised a call on April 23 with African health ministers to discuss, among other things, a lack of information sharing, Yao said. He declined to say who was on the call, and Tanzania did not respond to requests for comment as to whether its minister participated.

The United Nations agency cannot compel cooperation and must tread carefully. When WHO officials expressed concern in late April about a lack of measures to contain the virus in Burundi, the tiny East African nation expelled its top representative and three other WHO experts without explanation on May 12.

Burundi was one of the first African countries to shut its borders in March, which seemed to slow the virus’ spread initially. But the country saw an uptick in suspected cases after rallies were held in the run-up to May 20 general elections, a health care provider said, speaking on condition of anonymity.

Burundi’s 55-year-old president, Pierre Nkurunziza, died in early June amid speculation he had come down with COVID-19. The government said in a statement he had suffered a heart attack. An air ambulance service told Reuters it had flown his wife, Denise Bucumi, to Kenya on May 21 but declined to confirm reports in the Kenyan media that she had sought treatment for the coronavirus. A family spokesman declined to comment.

Burundi’s new president, Evariste Ndayishimiye, has promised measures to tackle the pandemic, including mass testing of people in areas suspected of being epicentres of the virus.

Another African state to fall out with the WHO was Equatorial Guinea. It hasn’t shared figures with the U.N. agency since late May, when its government accused the WHO of inflating the caseload and demanded that it recall its representative. The WHO blamed a “misunderstanding over data” and denied any falsification of figures.

Mitoha Ondo’o Ayekaba, Equatorial Guinea’s deputy health minister, did not respond to repeated requests for comment on the dispute. The Central African country has continued to provide periodic updates to the Africa CDC, which puts the number of confirmed cases there at 3,071 with 51 deaths.

While some countries won’t share information, others can’t: Their health systems are too broken to carry out any large-scale testing, surveillance or contact tracing.

“Eve at the best of times, collecting quality data from countries is not easy because people are stretched thin,” said John Nkengasong, director of the Africa CDC. “Combine that with an emergency, and it becomes very, very difficult.”

example, Islamist militants and ethnic militias operate across vast swathes of Burkina Faso, Niger anali, making it impossible for governments there to establish a nationwide picture of the spread of the illness.

As in other countries, a shortage of kits has led Burkina Faso to largely limit the number of tests it conducts to contacts of confirmed cases and people arriving from abroad. This means there is little data on local transmission, health ministry reports show.

Some countries, like Cameroon and Nigeria, have decentralised testing, but many others have very little capacity outside their capitals, said Franck Ale, an epidemiologist with the international aid group Medecins Sans Frontieres (Doctors Without Borders).

Democratic Republic of Congo, a nation of 85 million that was already battling Ebola, was quick to suspend international flights and lock down parts of the capital Kinshasa when the virus hit in mid-March.

However, it took three months before the government was able to process tests outside Kinshasa, said Steve Ahuka, a member of Congo’s COVID-19 response committee, citing a lack of laboratories, equipment and personnel. In many areas, it still takes two weeks to get results, said two doctors.

South Africa, the continent’s most advanced economy, is one of the few to have rolled out mass testing. But it had a backlog of more than 63,000 unprocessed specimens as of June 10, because global suppliers were unable to meet its demand for laboratory kits, according to the health ministry. South Africa’s national laboratory service declined to disclose the current backlog.

In the absence of comprehensive testing data in other parts of the world, researchers look to different yardsticks to judge the prevalence of the coronavirus, including reviewing the number of deaths that exceed the average for the time of year.

But even that is not possible in most of Africa because data from previous years is lacking. Only eight countries – Algeria, Cape Verde, Djibouti, Egypt, Mauritius, Namibia, Seychelles and South Africa – record more than 75% of their deaths, according to the United Nations. Ethiopia records less than 2%, the country’s health ministry said.

Without information about how severe an outbreak is and what resources are available to cope with it, nations risk lifting lockdowns too soon or maintaining them too long, said Amanda McClelland of the U.S.-based health policy initiative Resolve to Save Lives.

“The big gap for us is really understanding the severity of the outbreak,” she said. “Without clarity on data, it is very hard to justify the economic pain that shutting down countries causes.”
