The Sokoto State Covid-19 Rapid Response Team on Wednesday said it has received 170 alerts which it was investigating.
The team leader, Dr. Ali Inname, revealed this to Daily Trust in a phone interview.
Inname, who is the Commissioner of Health, added that 18 cases had so far been tested negative.
He said that the state would embark on house-to-house search of Lagos and Abuja returnees.
This, he said, is to ensure all returnees are tracked down, isolated and tested for coronavirus.
The measures is to forestall the outbreak of the disease in the state, according to him.
Lagos and Abuja combine to make more that half of the cases recorded so far in the country.
