The Coordinator, Technical Response Team, Covid-19, Dr. Tijani Hussaini, said this on Channels Television on Monday.
He said Kano, being a predominantly Muslim state, usually buries its dead almost immediately which, therefore, makes it nearly impossible to determine the cause of death of a person.
He said the state government also received reports from social media about the mysterious deaths but the state lacked records of normal death rates in the state and so there was no baseline with which to compare the recent deaths.
The coordinator said the probe was being conducted in conjunction with the Nigerian Centre for Disease Control and other partners.
Earlier, the Kano State Government had said the recent deaths in the state were caused by “complications arising from hypertension, diabetes, meningitis and acute malaria”.
The state Commissioner of Information, Muhammad Garba made this known in a statement on Sunday night.
