The Prime Minister's Office has already clarified Modi's comments, and said attempts are being made to give a "mischievous interpretation."
The chief minister reiterated that the spread of the infection in Puducherry and Karaikal regions was largely due to the people from neighbouring Tamil Nadu districts visiting the Union Territory.
"We have however tightened our vigil to prevent the people from stepping into Puducherry," he said.
The territorial government would appoint on contract basis doctors, nurses and workers under the ASHA scheme to strengthen manpower in hospitals to respond to the needs of the Covid-19 hit patients,he added.
