Seventy new coronavirus cases were recorded in Lagos on Sunday, with 16 others announced in other states.
It is the highest figure the country or any state would get in a day.
The 86 make the total number of confirmed infections in the country 627.
The rise is due to communal testing that Lagos State Government has begun, with the Health Commissioner , Prof Akin Abayomi, saying test centres have now been opened in each local government.
The Nigeria Centre for Disease Control made this known via its Twitter handle on Sunday.
It also said the total number of fatalities recorded from the virus in Nigeria has increased to 21.

“One case previously reported in Kano has been transferred to Jigawa state. Therefore, the total number of confirmed cases in Kano is 36 as of the 19th of April 2020.
