Authorities in Nigeria's sprawling megacity Lagos on Thursday announced they were shuttering schools and limiting religious gatherings as the country scrambles to halt the spread of coronavirus.
"After consulting with our healthcare professionals over COVID-19, we are closing down schools and limiting religious gathering," Lagos state governor Babajide Sanwo-Olu wrote on Twitter.
"We are limiting gatherings and events to no more than 50 people and appropriate social distancing must be observed."
The state government said schools in the city of 20 million people would be shut from Monday.
Africa's most populous nation has so far recorded just eight confirmed cases of COVID-19 and is following other countries on the continent in ratcheting up its response to the global pandemic.
The central government on Wednesday announced an entry ban on 13 countries worst-hit by coronavirus.
Enforcing the new restrictions on the chaotic and overcrowded streets of Lagos will be a major challenge for the authorities.
The city is home to an array of so-called "megachurches" where thousands of worshippers typically gather each weekend for services.
