Multiple NBA players have tested positive for COVID-19 twice?

There is currently no proven evidence that shows an individual who tests positive for COVID-19 can't eventually become infected with the virus a second time. It appears the NBA is dealing with that reality following the holiday season. 

ESPN's Brian Windhorst and Zach Lowe reported on Tuesday that multiple NBA players who previously tested positive for the coronavirus have recently tested positive again. Windhorst and Lowe added this isn't surprising, as the CDC has expected reinfections since the start of the pandemic. 

It's unknown how many supposed asymptomatic players who tested positive for the virus earlier in the year produced so-called "false positives." Multiple leagues and competitions, including the NBA, have confirmed "false positive" cases since the spring and summer months. The CDC hasn't determined how long somebody who battles COVID-19 is immune from becoming infected a second time. 

While more is known about COVID-19 among medical professionals and experts today than 12 months ago, this news serves as a reminder that the situation continues to evolve and change even as some receive vaccines. As CNN's Valentina di Donato, Aleks Klosok and Ben Morse noted, Juventus and Argentina striker Paulo Dybala tested positive for COVID-19 six straight weeks last spring. 

Earlier on Tuesday, Wednesday's matchup between the Boston Celtics and Orlando Magic became the fifth NBA game of the campaign postponed because of issues related to COVID-19.
