As Nigeria recorded its 97th COVID-19 case late on Saturday, a review of official data shows that the number of confirmed cases rose by 340 per cent in a week.
COVID-19 is a deadly respiratory disease caused by the coronavirus.
According to the latest breakdown by the Nigeria Centre for Disease Control (NCDC), Lagos State leads with 59 cases, followed by 16 in Abuja, Ogun - 3, Oyo - 7, Edo - 2, Bauchi - 2, Enugu - 2, Osun - 2 while Ekiti, Kaduna, Rivers and Benue states have one case of the infection each.
While one death has been recorded, at least three patients have so far been discharged after they fully recovered from the disease.
An analysis of the recorded cases this week, when compared with the previous week, revealed that an additional 75 persons tested positive this week.
This represents a 340.9 per cent increase, the highest weekly increase Nigeria has recorded since its index case on February 24.
The Lagos State Government has projected that the numbers of cases in the state might reach 39,000 if good social distancing was not adhered to by the public.
"Our Mathematical modelling shows that worst case scenario we might have 39,000 cases in Lagos State; however, if we practice good social distancing, we can limit that to about 13,000," the Commissioner for Health, Akin Abayomi, said on Friday.
Mr Abayomi said combining social distancing with active constant tracing would help to reduce the cases further, noting that the figure was minimal compared to the numbers of cases in other parts of the world.
"The figures may seem alarming at this point, but this is just to emphasise the importance to the Lagos Community to follow the instructions of the Incidence Commander to ensure they practice good social distancing.
"Social distancing is the key to bring the outbreak under control, because that way, we are not giving the virus the opportunity to spread from person to person," he said.
