NAIROBI (AFP) -- Kenya announced Friday the first confirmed case of coronavirus in East Africa, as the region so far unscathed by the global pandemic scaled up emergency measures to contain its spread.

A 27-year-old Kenyan woman tested positive for the virus on March 12 in Nairobi, a week after returning from the United States via London.

She was in a stable condition and recovering, Health Minister Mutahi Kagwe told reporters.

"We wish to assure all Kenyans that the government will use all the resources available to fight coronavirus," he said, as the government rolled out a raft of new containment measures.

The government had traced all the contacts of the patient since she arrived back in Kenya on March 5, he added.

"At the moment, there is absolutely no need for panic and worry," he said.

Kenya becomes the 12th country in Africa to confirm cases of the virus that has swept the globe, infecting more than 130,000 people and killing nearly 5,000.

But to date the continent has been spared the worst of the pandemic.

Only five people have succumbed to coronavirus so far -- all in north Africa -- with the sub-Saharan region recording no deaths and very low numbers of confirmed cases.

But countries in East Africa -- which until the positive case in Kenya, had only recorded negative test results -- have been taking precautions.

Some flights have been restricted, with Kenya Airways suspending its route to Rome, and charter flights from Italy to the Kenyan coast on hold.

It has also suspended international conferences, a top earner in Nairobi, a hub for such events in the region, and non-essential travel abroad for politicians.

The government announced more expansive restrictions Friday, including a temporary ban on major public gatherings, prison visits and activities between schools.

Other countries in the region have been rolling out their own measures.

In Rwanda, which shares a border with the Democratic Republic of Congo, which has confirmed cases, washing basins with soap and sanitiser have been placed on streets for commuters to use before boarding buses.

Authorities in Kigali, the capital, have also banned concerts, rallies and trade fairs -- although like in Kenya and Uganda, church services have been proceeding and bars, restaurants and entertainment precincts remain open.

Neighbouring Burundi, meanwhile, has quarantined 34 people in a hotel in Bujumbura as a precaution.

Uganda has ordered that visitors from a number of affected countries self quarantine for 14 days, or consider simply not visiting at all.

South Sudan's health ministry said meanwhile that it was "temporarily suspending direct flights between South Sudan and all affected countries"

Kagwe, the Kenyan health minister, also addressed a rumour circulating on social media that people with black skin cannot contract the virus.

"I would like to disabuse that notion. The lady (confirmed with coronavirus in Kenya) is an African, like you and I," he said.
