The Nigeria Centre for Disease Control has recorded 387 additional COVID-19 infections in 15 states and the Federal Capital Territory.
The centre posted these figure on its Facebook page on Tuesday morning in an update on the pandemic.
The News Agency of Nigeria reports that the 387 new infections represent an increase from the 365 cases reported on Sunday.

“Everyone in areas of substantial high transmission should wear a mask, even if vaccinated,” it advised.
The NCDC said the number of active coronavirus infections had again risen to 10,135, an increase from 8,492 reported on Monday.
