India’s festival of Holi, which marks the advent of spring, was reportedly toned down this year compared with previous celebrations over fears of the coronavirus that has been rattling the world economy.

On Tuesday, brightly colored powder filled the air in parts of North India. But in the capital, New Delhi, many events were canceled as the number of confirmed cases of COVID-19 in the country rose to nearly 50.

The festival is widely celebrated in India, Nepal and other South Asian countries.

Most years, millions of people from toddlers to the elderly throw powder at each other and play with water balloons and squirt guns. But this year Prime Minister Narendra Modi tweeted that he would not participate in public Holi celebrations because of the virus outbreak.

"Yes, it's coronavirus that made us cancel our programs," said Anshuman Ghulati, festival director of Holi Moo, one of the biggest Holi events in New Delhi, which drew some 7,000 people from around the world last year. "People are scared this year, we have canceled our event.”

Other groups in New Delhi also canceled their plans.

Atul Goyal, president of United Residents Joint Action, said there would be no gala lunches or water dance events.

"Considering the coronavirus outbreak, you are advised to cancel Holi gatherings, in particular playing with water and touching of nose, eyes and lips and shaking hands," the group said in an advisory.

Yet many ignored the recommendations in other parts of the country. In the northern state of Uttarakhand, people danced and smeared each other with colors.

Sellers of colored powder and water guns said their sales had plunged.

"The fear that customers have over the coronavirus and the large number of people that are getting sick has made them slightly disinterested in celebrating Holi. So, our sales have become very less this Holi," vendor Jitender Pandey said.

For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.
