There was no social distancing for these early-morning straphangers.

Startling video shows subway riders packed like sardines Tuesday morning because of reduced service — which the MTA pinned on coronavirus-related sick calls.

“This is our reality, we’re hopeless,” said restaurant manager Damaris Sierra, who filmed her packed 4 train headed into Manhattan from the Bronx at around 5:35 a.m.

Several people in the video are seen wearing standard medical masks, including a respirator-style version, or makeshift face coverings.

The B, Z and W trains were all out of commission Tuesday morning — along with a dozen other segments and express trains — after the MTA announced significant service cuts due to reduced staffing because of coronavirus diagnosis or exposure.

“Taking precautions against COVID-19 means we have fewer train crews available while our employees follow steps that health officials recommend for everyone,” the agency said.

Other morning straphangers have reported similarly frightening experiences to Sierra’s.

“And you realize that by eliminating the B, that my Q was jammed this morning,” Twitter user @linerider posted Tuesday. “People sitting squashed together and standing shoulder to shoulder. Brilliant as always MTA.”

“@MTA what’s with this modified schedule *BULLS–T* you’re letting the platforms pile up with people doing more harm then good. I’ve been waiting on a 2 train at Newkirk Ave well over 30 minutes already,” posted @bklynike.

Gov. Andrew Cuomo ordered all non-essential businesses in the state to close by 8 p.m. last Sunday. But pharmacies and grocery stores, among other essential businesses, remain open.

The MTA announced last Thursday that 23 employees have tested positive for the virus.

An NY1 report noted that 1,090 subway trips were canceled from March 18 through 22 — compared with the 126 trips canceled March 4 through 10.

The MTA would not say how many trains have been canceled by coronavirus concerns.

Agency spokesman Shams Tarek insisted it is “running as close to a full weekday schedule … as possible,” and suggested that Sierra was lying about when her video was taken.

“While we don’t have evidence of when this video was recorded, the subway is far less crowded than usual as evidenced by precipitous drops in ridership across the city,” Tarek said in a statement.
