So far 233 cases of the deadly virus had been registered in sub-Saharan Africa which makes it the least-affected region in a global pandemic.
But, Tedros Adhanom Ghebreyesus, WHO Director-General, speaking to journalists in a virtual news conference on Wednesday said Africa needs to wake up as official numbers of COVID-19 cases do not likely reflect the full picture.
Few hours ago, Nigeria confirmed five new cases making it eight positive cases of Coronavirus.
The Buhari-led Government also placed a travel ban from 13 high risk countries to curb the spread of the virus.
Tedious warned that numbers of positive cases could scale up quickly if care is not taken.
Tedros said: “Till date more than 200,000 people have been and more than 8,000 killed with Africa as the least affected.
“Africa should wake up,Probably we have undetected cases or unreported cases.
“Even if there truly were no more than 233 cases of the disease in Africa, he warned that that number could scale up quickly.
“In other countries, we have seen how the virus actually accelerates after a certain tipping point, so the best advice for Africa is to prepare for the worst and prepare today
“WHO’s recommendation is actually that mass gatherings should be avoided.”
