The Jazz forward, who was the first NBA player to test positive for COVID-19, on Sunday tweeted some of the effects he’s felt while self-quarantining.

“Just to give you guys an update, loss of smell and taste is definitely one of the symptoms, haven’t been able to smell anything for the last 4 days,” Gobert wrote. “Anyone experiencing the same thing?”

According to the British Association of Otorhinolaryngology — which represents ear, nose and throat specialists — the loss of taste and smell could be crucial warning signs in “hidden carriers” of the novel coronavirus, and often appears in patients who show none of the earlier known symptoms.

Gobert tested positive for coronavirus on March 12, which led to the the postponement of Utah’s game against the Thunder and the eventual suspension of the NBA season.

Nine other NBA players, including Gobert’s teammate Donovan Mitchell, have also tested positive for coronavirus.

Gobert has admitted to being “careless” after touching reporters’ recording devices prior to his positive test and “would have took this thing more seriously.”

Since then, the 27-year-old has publicly urged everyone to take precautionary measures. He also made a $500,000 donation to aid the fight against coronavirus.
