The three-member multidisciplinary teams are headed by joint secretary-level officers in the Union health ministry. They will work closely with the state administration and ascertain the reasons for a recent surge in infections.
The teams will also coordinate with health authorities of the states for requisite Covid-19 control measures to break the chain of transmission.
"The state governments have been advised for regular critical review of the emerging situation with concerned district officials to ensure that gains made so far in Covid management are not lost," the health ministry said in a statement.
The Centre has also written to Maharashtra, Kerala, Chhattisgarh, Madhya Pradesh, Gujarat, Punjab and Jammu and Kashmir, which have been witnessing a rise in Covid-19 cases, along with decreasing proportion of RT-PCR tests and a rise in positivity in some districts.
In a letter, the health secretary has asked Maharashtra, Kerala, Chhattisgarh, Madhya Pradesh, Gujarat, Punjab and J-K to focus on undertaking aggressive measures, including amplified RT-PCR testing, to curb the spread of the virus.
"The states have been advised to increase testing in a focussed manner in the affected districts with the appropriate split of RT-PCR and Rapid Antigen Tests and to also ensure that all symptomatic negatives of antigen tests are compulsorily tested via RT-PCR tests. The positive persons must be promptly isolated/hospitalised, all their close contacts should be traced and also tested without delay," the ministry said.
