Stand clear of the barfing straphanger.
Six people fell ill inside a Harlem subway station — and trains had to bypass the stop for more than a half-hour — after a person vomited on the platform Monday morning, police said.
The NYPD’s elite Emergency Service Unit was even brought in to conduct a precautionary air-quality test after the riders started dropping like flies, sources said.
Patient Zero got sick at the 125th Street station near Lexington Avenue shortly after 9 a.m., causing a chain-reaction that left six other riders coming off different trains nauseous and dizzy at the sight, cops said.
All seven people, including the person who threw up, were taken to Harlem Hospital for treatment.
Trains bypassed the station – which services the No. 4, 5, and 6 lines – for 35 minutes between 9:15 a.m. and 9:50 a.m. the air-quality test was done.
The results of the test came back negative, police said.
