Top-ranked tennis player Novak Djokovic, his wife and their foundation are donating 1 million euros (about NZ$1.8 million) to help buy ventilators and other medical equipment for hospitals in Serbia.
Djokovic says his foundation's staff "will be monitoring everything" to get the equipment in place.
His wife, Jelena, is the global director of the Novak Djokovic Foundation. She says ventilators needed to help Covid-19 patients range in price from 10,000 to 50,000 euros.
The 32-year-old Djokovic won the Australian Open in January for his 17th Grand Slam title. Among men, only Roger Federer, with 20, and Rafael Nadal, with 19, have won more.
