A man claimed he had a gun — and COVID-19 — during a robbery Thursday inside a Manhattan laundromat, police said.

The man walked into the 24-hour Green Laundromat on St. Nicholas Avenue in Sugar Hill around 3 a.m. and slipped a note to a clerk, cops said.

The robber claimed he had a firearm, and perhaps even scarier, the potentially deadly virus, police said.

The suspect then went behind the counter and fished money out of a bowl before he fled with just $23.

No one was injured, cops said.

The suspect remains on the loose.
