The New York Times went beyond the raw data that is quoted daily by Johns Hopkins University which tracks the incidence of COVID-19 in the United States (over 1.6 million confirmed cases, and over 98,000 deaths - the highest COVID-19 figures in the world!)
Whereas North African countries (Morocco, Egypt, Tunisia, Libya and Algeria) where there are high figures of COVID-19 enforced rules of physical distancing, many worshippers South of the Sahara threw caution to the winds, with perhaps the notable exceptions of Ghana and Senegal.
In Tanzania, a country that has been "Magufulifised" to paraphrase the eminent Kenyan Professor, PLO Lumumba, the leaders pretended to be aware of the need for physical distancing but the worshippers who trooped to mosques in Dodoma and elsewhere in the country could not be bothered.
The point I am really trying to make is that in Burundi, not even the country's Muslim population had any need to worry about COVID-19.
However, the fact that Muslim leaders were also not entirely quiet soon became evident as many states in the North began to announce that religious worship was in order, and that mosques and churches could re-open even as COVID-19 figures in Nigeria increased geometrically.
