So also, the Lagos State Ministry of Health affirmed that there is no confirmed case of coronavirus in the state.

Akin Abayomi, the commissioner for health, said the suspected carrier of the infection arrived Nigeria from China on Wednesday and submitted himself for quarantine.

“The subject in question is an adult male Nigerian who arrived from China 4 days ago,” the commissioner said.

“He was in Shanghai throughout his stay in China and during his stay he did not have any contact with anyone who was ill or from Wuhan region.”

The commissioner said the report from the epidemiology officers and the doctor that attended to the subject at the hospital in Lekki indicated that he is in perfect health with no symptoms of the virus.

“He is, therefore, clinically not a suspected case of nCoV as he is not exhibiting any symptoms. Nevertheless we will continue to monitor his welfare till the end of his self quarantine period,” the ministry said.

Mr Abayomi had earlier said that the state government was working with the Chinese embassy in Nigeria to prevent the entry of coronavirus into the state.

The agency said the individual had truly arrived the country from China last week but he had went on a routine medical check-up as advised by his employers as soon as he got back to Nigeria.

“This individual returned from China last week and went for a routine medical check as requested by his employers. He showed no symptoms of illness and has not been diagnosed with the novel coronavirus virus”.

Hence,  NCDC, urge members of the public to disregard rumours and discourage further spread.” NCDC, port health service and state epidemiologist are aware of the process of case identification and confirmation. We will investigate every suspect case to ensure Nigerians are safe.”

Though no case has been reported, NCDC advised Nigerians to take necessary precautions while travelling or returning to the country.

Those who had travelled from China to Nigeria in the last 14 days are also advised to report immediately to NCDC through the existing communication centres, if they feel sick.
