Every year, around carnival time, members of the NGO Doctors of Joy dress up as 'clown doctors' to cheer up sick people in hospitals and their relatives.

It is carnival time in Brazil and the carnival capital of the world, Rio de Janeiro, is already in high spirits, anticipating the celebration from 9 February to 12 February.

During the festival, while an estimated 2 million people take to the streets in the city, at such a time, Doctors of Joy volunteers visit various hospitals to share the joy of the festival with people who are unable to share in it.

According to the NGO, its volunteers make approximately 75,000 visits every year to hospitals in Sao Paulo, Rio de Janeiro, Recife and Belo Horizonte.

The 'clown doctors' perform arts such as circus, music and poetry for patients in public hospitals and cover more than 27 thousand people.
