Mali’s largest jail is a squalid and overcrowded colonial-era throwback that in theory is an open invitation to coronavirus. Instead, staff at Bamako Central Prison say that so far they have kept the dreaded virus at bay, thanks to time-honoured techniques of hygiene and self-help. Outside the penitentiary’s ochre walls, the Malian capital has registered most of the country’s 2,577 infections and 125 deaths. Inside, the number of recorded cases is precisely zero. “From the start of the pandemic, we did everything we could to prevent it from getting in,” said prison warden Colonel Adama Guindo, wearing a face mask. Hand cleanliness, temperature checks for visitors and an innovative scheme for inmates to make face masks have been key. There is every reason to be vigilant. The prison is an ideal breeding ground for coronavirus. Built by French colonial authorities in 1951, the prison was designed for 400 inmates but currently holds 2,100. Hundreds of people are crammed on top of each other in filthy cells. Common criminals and captured jihadists from Mali’s eight-year conflict live cheek by jowl: cooking together, running tattoo parlours and trading cigarettes. Mali’s number of COVID-19 cases pales in comparison with virus-stricken countries such as the United States or Brazil. But there are fears about the capacity of the war-torn Sahel nation of some 19 million to handle a large outbreak. Large swathes of the country lie outside the control of the government, which has been struggling to contain a jihadist insurgency that first emerged in 2012 and which has claimed thousands of lives. Overcrowding In other West African countries, coronavirus cases in overcrowded prisons have provoked severe tensions. Thirty-one people died in a prison riot in Sierra Leone’s capital Freetown in April, for example, shortly after the city’s overcrowded jail registered its first case. In Mali’s Bamako Central Prison, officers transferred about 600 inmates to another jail in the city’s suburbs to reduce overcrowding. Some prisoners also received a presidential pardon. But even with those measures, the prison remains hugely overcrowded, mostly because of the vast number of people held in pre-trial detention.
