The coronavirus pandemic — and the quarantine it’s brought on — is fraying nerves. Wilson Chandler found that out Wednesday.

A day after four Nets tested positive for COVID-19, Chandler was happily watching old movies when he got what he felt was a less-than-tactful call from his building manager.

“Building manager called me saying ‘Oh, I seen Nets players had the virus. We would like to know your status. And if you could possibly stay out of the lobby etc. We can’t afford to lose our staff,’” Chandler tweeted.

After the Nets returned from California on March 12, they all got tested for COVID-19 — something that recently drew criticism from Mayor Bill de Blasio, even though the team footed the bill.

Four players came back positive on Tuesday — Kevin Durant and three unidentified others — and the team stated that the quartet was “presently isolated and under the care of team physicians.”

All the players were asked to “remain isolated.” Chandler had just been tweeting about movies, noting “Contagion” and “The Big Short” seemed fitting considering the pandemic and resulting stock market plunge, and praising Russell Crowe’s “A Beautiful Mind” just before the interaction.

Still, nerves are frayed over the pandemic that has infected 200,000 worldwide and more than 1,300 in New York City alone as of Wednesday morning. And news of the Nets testing positive obviously spread, including to the 32-year-old Chandler’s building manager.

“Didn’t even ask was I ok, one. And two, she didn’t ask me if I had been tested and if it was negative or positive,” Chandler tweeted. “F–k this building man. I’m going home.”

At the moment, it’s not exactly clear what “going home” meant.

Everybody who came into contact with those four Nets — teammates, family, opponents who’d faced them recently — would be expected to self-quarantine and take appropriate precautions.

“Has to be 300 + plus ppl in this building coming and going. Plus Fed Ex and UPS deliveries, Amazon etc,” Chandler tweeted, adding, “F–k that lady man.”
