Tanzanian President John Magufuli, Africa’s most prominent Covid-19 denier, disappeared from public sight 17 days ago. Now, he is widely rumored to be seriously ill with the same virus that he has dismissed and downplayed over the past year.

Last May, Magufuli declared that “Tanzania has beaten coronavirus” after ordering three days of national prayer. The president abruptly stopped updating the number of cases, and assured foreign tourists that Tanzania’s game parks and Indian Ocean resorts were open for business, leading to a wave of travel advisories  cautioning travelers to avoid the country.

Since then, he has scoffed at wearing masks, criticized regional neighbours for imposing lockdowns, and rejected coronavirus vaccines until his government independently verifies them. In early January, Magufuli told the visiting Chinese foreign affairs minister, Wang Yi, that “there is no coronavirus in Tanzania.”

Then, after appearing at an event in Tanzania’s commercial capital Dar es Salaam on Feb. 24, Magufuli disappeared from public view.

This week, the leading newspaper in neighboring Kenya, the Daily Nation,: “The leader of an African country who has not appeared in public for nearly two weeks is admitted to Nairobi Hospital for Covid-19 treatment, even as his government remains mum on his whereabouts.”

Within hours, speculation was rife that Magufuli had been secretly flown to Nairobi for emergency medical attention and later airlifted for treatment in India. Insider has not been able to confirm these reports.
