Nigeria has recorded 11 new cases of coronavirus, bringing the total number of cases to 81.

The Nigeria Disease Control Centre made this known late on Thursday.

It said eight new cases were recorded in Lagos State, two in Enugu and one in Edo.

Prime Minister Boris Johnson has tested positive for coronavirus, the government has said.

Mr Johnson has mild symptoms and will self-isolate in Downing Street, after being tested at No 10 by NHS staff.

“He was tested for coronavirus on the personal advice of England’s chief medical officer, Professor Chris Whitty,” a statement said.

He will still be in charge of the government’s handling of the crisis, the statement added.

In a tweet, Mr Johnson said: “Over the last 24 hours I have developed mild symptoms and tested positive for coronavirus. I am now self-isolating, but I will continue to lead the government’s response via video-conference as we fight this virus.

The Special Assistant to the Lagos State Governor on Health, Dr Tunde Ajayi, has disclosed that six of the patients at the Infectious Disease Hospital have recovered.

Ajayi via his twitter handle, @thetundeajai, said the patients would be discharged soon.

“Six of our #COVID19 inpatients have recovered and will be discharged soon. There is something Lagos is doing right. Lagos takes the lead,” he wrote.

According to the Nigeria Centre for Disease Control, 51 cases were confirmed in the country as of 11:25 pm on March 25.

“Out of the 51 confirmed cases, two have been discharged, while one death has been recorded. Lagos has 32 confirmed cases,” the NCDC wrote on its website.
