Del Potro, 30, was in Miami doing rehab following a second surgery for his kneecap injuries. He has now gone back to Argentina and has begun 14 days of self-isolation.
"Of course, I am already following quarantine at home and will try to go on with my recovery here," he said in a translated tweet. "It is very important to take care of each other. Also, a big hug to the doctors and health professionals during this difficult times."
Quería saludarlos y contarles que después de casi dos meses en Miami por la rehabilitación de la rodilla, esta mañana tempranito pude volver a casa ????????. Ya estoy cumpliendo con la cuarentena como corresponde. Intentaré seguir la recuperación lo mejor que se pueda. Es muy importante cuidarnos entre todos. Cumplir con la cuarentena, hacerle caso a las indicaciones de los especialistas, tener empatía y ser responsables. Es un momento especial, único, que necesita de todos. Quiero agradecer al comandante del vuelo de @aerolineas_argentinas que llegó esta mañana. A toda su tripulación, gente que trabaja poniendo en riesgo su salud, y muchos de ellos encima lo hacen a voluntad. Gracias por los cuidados y la buena onda durante el vuelo. También quiero mandarles un abrazo fuerte a los médicos y profesionales de la salud en este momento difícil. #Yomequedoencasa #QuedateEnCasa . . Early today I arrived home after two months in Miami. Of course, I am already following quarantine at home and will try to go on with my recovery here. It is very important to take care of each other. Please follow the specialists' advice, be empathetic. It is a special, unique moment and we need to give our best. I want to thank the commander of the Aerolineas Argentinas flight that landed this morning in Buenos Aires. Thanks to all its crew for their kindness during the flight. Also, a big hug to the doctors and health professionals during this difficult times.
Tunisia's Jaziri is doing the same.
"I have completed the necessary medical examination," he said in a translated Facebook video. "The voluntary quarantine will allow me to avoid infecting others if it is confirmed as coronavirus.
"I call on all my compatriots to respect the rules of voluntary quarantines."
They join Bernard Tomic, who is in Miami and saying he has symptoms, and Yaroslava Shvedova, who is in required quarantine but says she has not tested positive for the virus.
Whether they're isolating or not, many players remain in touch with others like everyone else: through their phones.
The ATP pros have been communicating by phone instead, Diego Schwartzman told Elgnache Radio.
"There is a Whatsapp group among the Top 100 players, and we talk a lot about the issues of the tournaments and the suspension for coronavirus. Novak Djokovic is like a moderator, talks a lot in this group," he said. "On coronavirus, there are a lot of memes, and we laugh a lot."
Schwartzman has also been recovering from a leg injury experienced during Buenos Aires.
There has been plenty to discuss, with the tour cancelling the rest of its clay events and the French Open announcing that it is aiming to be played the week following the US Open. Some players have complained publicly that they were not consulted about the French move beforehand.
The tours have also suspended all tournaments for the next two and a half months and locked the rankings."
