Prime Minister Narendra Modi and Delhi Chief Minister Arvind Kejriwal expressed their gratitude to all doctors on National Doctors' Day on Thursday.

Remembering the contributions of the doctors, Modi said India's strides in the world of medicine are commendable and have contributed to making the planet healthier.

The Doctors' Day is observed in the honour of noted doctor and former West Bengal chief minister Bidhan Chandra Roy, whose birth and death anniversaries fall on July 1.

"On Doctors Day, my greetings to all doctors. India's strides in the world of medicine are commendable and have contributed to making our planet healthier," Modi tweeted.

He also shared an audio clip from his 'Mann Ki Baat' broadcast last Sunday in which he talked about Doctors' Day.

"We are all grateful for the contribution of doctors in the Corona period. Our doctors have served us without caring about their lives. Therefore, this time National Doctors' Day becomes all the more special," Modi had said in his radio broadcast.

Thanking all doctors for their service during the pandemic, Arvind Kejriwal said the debt of doctors who served people day and night during the coronavirus pandemic cannot be repaid.

"Our doctors served people day and night during the pandemic. We cannot repay their debt throughout or lives. Salute to all the doctors on National Doctors' Day who saved lives of lakhs of people and prevented their families from crumbling, " Kejriwal tweeted in Hindi.
