Chidi Samuel| Nigeria on Monday reported 321 new cases of the novel coronavirus, on a day the Lagos state commissioner for health Prof Akin Abayomi came down with the highly contagious virus.
In a Tweet on Monday night, the Nigeria Centre For Disease Control said the new infections were recorded in 24 states and the FCT.
According to the NCDC, Lagos recorded the highest number of cases with 98, followed by FCT-34, Kaduna-30, Nasarawa-25, Benue-21, Plateau-17, Rivers-15
Adamawa-11, Ogun-11 and Enugu-9.
Other states with new infections include, Edo-8, Delta-7, Ekiti-7, Gombe-5, Ebonyi-4
Bayelsa-3, Kano-3, Ondo-3, Cross River-2, Imo-2, Kebbi-2, Niger-2, Abia-1, and Bauchi-1.
The health agency further noted that so far, Nigeria has 52,548 confirmed cases of the novel coronavirus with 39,257 recoveries and 1004 fatalities.
-Hong Kong reports ‘first case’ of virus reinfection
Hong Kong scientists are reporting the case of a healthy man in his 30s who became reinfected with coronavirus four and a half months after his first bout.
They say genome sequencing shows the two strains of the virus are “clearly different”, making it the world’s first proven case of reinfection.
The World Health Organization warns it is important not to jump to conclusions based on the case of one patient.
And experts say reinfections may be rare and not necessarily serious.
There have been more than 23 million cases of coronavirus infection around the world.
Those infected develop an immune response as their bodies fight off the virus which helps to protect them against it returning.
The strongest immune response has been found in the most seriously ill patients.
But it is still not clear how strong this protection or immunity is – or how long it lasts.
And the World Health Organization said larger studies over time of people who had previously had coronavirus were needed to find out more.
This report, by the University of Hong Kong, due to be published in Clinical Infectious Diseases, says the man spent 14 days in hospital before recovering from the virus but then, despite having no further symptoms, tested positive for the virus a second time, following a saliva test during airport screening.
“This is a very rare example of reinfection,” said Brendan Wren, professor of microbial pathogenesis, at London School of Hygiene and Tropical Medicine.
“And it should not negate the global drive to develop Covid-19 vaccines.
“It is to be expected that the virus will naturally mutate over time.”
Dr Jeffrey Barrett, senior scientific consultant for the Covid-19 genome project at the Wellcome Sanger Institute, said: “Given the number of global infections to date, seeing one case of reinfection is not that surprising even if it is a very rare occurrence.
“It may be that second infections, when they do occur, are not serious – though we don’t know whether this person was infectious during their second episode.”
Prof Paul Hunter, from the University of East Anglia, said more information about this and other cases of reinfection was needed “before we can really understand the implications”.
