Indian Prime Minister Narendra Modi took to Twitter today in an attempt to allay fears over the spread of coronavirus.

"There is no need to panic. We need to work together, take small yet important measures to ensure self-protection," Modi wrote.

Modi added that he has reviewed preparedness efforts on the coronavirus and that different ministries and states are working together, including screening people arriving in India to providing prompt medical attention.

India, which has reported six infections, has suspended issuing visas to citizens of several of the countries hardest-hit by the coronavirus.

According to a news release from the Indian government, all regular visas issued on or before March 3 and granted to nationals of Italy, Iran, South Korea and Japan who have not yet entered the country have been suspended with immediate effect.

An earlier suspension of visas for Chinese citizens remains in force.

The statement says those requiring essential travel to India may seek fresh visas from the nearest Indian embassy or consulate.

India has also asked its citizens not to travel to China, Iran, South Korea and Italy, and advised against any non-essential travel to other coronavirus-affected countries.

Italian infected: The news of visa suspensions comes after a 69-year-old Italian man in Jaipur was confirmed to be infected with the coronavirus -- India's sixth confirmed case. Authorities are trying to track down 18 other Italian citizens who were traveling with the man.
