Tanzania's President John Magufuli is in good health and working normally, one of his diplomats told a broadcaster in Namibia, countering reports that he had been flown to Kenya and then India in a critical condition with coronavirus (Covid-19).

Magufuli, 61, is Africa's most prominent coronavirus sceptic. He has not been seen in public since Feb. 27.

Tanzanian opposition leader Tundu Lissu has cited medical and security sources saying the president was flown to the private Nairobi Hospital in neighbouring Kenya and then on to India in a coma.

But Tanzania's ambassador in Windhoek, Modestus Kipilimba, told the Namibian Broadcasting Corporation that was untrue.

"For me actually, what I know is that he's OK, he's going on with his job," he told NBC in an interview, without elaborating.

Kipilimba's comments were the first public assessment from a Tanzanian official about Magufuli's situation since concerns surfaced at the start of this week.

Kenya's Nation newspaper on Wednesday cited unidentified political and diplomatic sources saying that an African leader, which it did not name, was being treated for Covid-19 on a ventilator at a private Nairobi Hospital. [L1N2L80WJ]

The hospital has said nothing.

Tanzanian presidency and government spokesmen have not responded to Reuters requests for comment, and there has been no word either from the governments of Kenya or India.

ZANZIBARI NEXT IN LINE

According to the constitution, 61-year-old Vice President Samia Suluhu Hassan would take over for the rest of the five-year term if the president were unable to carry out his duties.

Born in Zanzibar, Suluhu has studied economics in England and worked for the United Nations' World Food Programme as well as holding various government posts prior to becoming Tanzania's first female vice-president in 2015 under newly elected Magufuli.

Nicknamed "The Bulldozer", Magufuli has frustrated the World Health Organization (WHO) during the pandemic by playing down the threat from COVID-19, saying god and remedies such as steam inhalation would protect Tanzanians.

The former chemistry professor has mocked coronavirus tests, denounced vaccines as part of a Western conspiracy to take Africa's wealth, and opposed mask-wearing and social distancing.

Tanzania stopped reporting coronavirus data in May last year when it had reported 509 cases and 21 deaths, according to the WHO, which has urged the government to be more transparent and to implement COVID-19 curbs.

Magufuli, from northwest Tanzania, was first elected president in 2015. He has faced accusations from Western countries and opposition parties of eroding democracy, which he denies.
