Tennis great Roger Federer has donated one million Swiss francs (Dh3.5m) to help support his "most vulnerable" compatriots through the coronavirus crisis.
The 20-time Grand Slam champion and his wife insist that "nobody should be left behind" as Switzerland battles against the global pandemic.
According to official figures reported to the World Health Organization, Switzerland has the ninth-highest number of infections in the world.
According to the Swiss health ministry, more than 8,800 people have tested positive for Covid-19, while 86 people had died as of Monday.
"These are challenging times for everyone and nobody should be left behind. Mirka and I have personally decided to donate one million Swiss francs for the most vulnerable families in Switzerland," world number four Federer, 38, said on Instagram.
"Our contribution is just a start. We hope that others might join in supporting more families in need. Together we can overcome this crisis! Stay healthy!"
On Friday, the Swiss government further tightened measures against the new coronavirus, banning all gatherings of more than five people, while anyone standing closer than two metres to others risks a fine.
The government had already ordered the closure of schools and all places of leisure, including restaurants, bars and non-food shops.
Last week, reigning Wimbledon champion Simona Halep said she would donate money to pay for medical equipment in her home country of Romania.
"We are so grateful for the bravery of our medical workers at these difficult times. I am committed to helping my country and have decided to donate medical equipment," Halep said on social media.
"This is the perfect opportunity to show that we know how to be supportive and responsible with our lives and those around us."
