People arriving in Tripura from states having a high prevalence of Covid-19 will have to undergo mandatory testing at the Agartala airport.
People arriving from abroad will also have to undergo Covid-19 tests in the airport.
A high-level state committee on Covid-19 prevention announced these guidelines.
However, the committee did not say anything about those arriving in Tripura by train and other vehicles.
10 per cent of those who come from other states will be tested.
Last year, the Tripura government had made it a rule that one in five train passengers arriving in the state would be tested for Covid-19.

Tripura has the highest Covid-19 mortality rate in Northeast India at 1.16 percent.
A total of 33,490 people have tested positive for the virus in Tripura.
While the recovery rate is 98.68 per cent, the disease claimed 389 lives in the state.
On Friday, members of the Technical Advisory Committee of doctors on Covid-19 advised against travelling outside the state unless emergency.
Most of the people who tested positive in the past few weeks have a travel history to some Covid-19 affected state.
Tapan Majumder, a member of the advisory committee said “Almost every person arriving in Tripura from Uttar Pradesh have found to be infected by the novel coronavirus.”
