Nigeria Centre for Disease Control said, on Thursday, that the use of masks is more effective protection against COVID-19 infection than face guards.
NCDC Director-General, Dr Chikwe Ihekweazu, said this during the Presidential Task Force briefing in Abuja.
The NCDC boss said face guard must be worn along with face mask.
Face guards have become common in the last couple of weeks with governors and other top government functionaries wearing it in public places.
Price of face guards ranges from N1, 500 to N4, 000.
