A ‘biohazard’ situation forced a United Airlines flight bound for Boston from Houston’s George Bush Intercontinental Airport Sunday morning to divert to Washington DC.

According to the New York Post, Flight 2477 had to undergo “a deep clean” upon landing due to a passenger becoming ill.

The incident apparently was severe enough to cause crew members to become sick and prompt passengers to request masks.

“I talked to the crew and it sounds like it’s quite bad back there. It’s still really bad,” a crew member was heard saying on audio from the flight.

“The crew is vomiting, and passengers all around are asking for masks,” the crew member continued.

“With this kind of being a biohazard I think we need to probably get this plane on the ground asap,” the crew member added.

From the New York Post:

The plane safely landed at Washington Dulles Airport, where none of the plane’s 155 passengers or its six crew members required medical help.

“The aircraft is currently undergoing a deep clean and we are working to get customers on their way to Boston soon,” the airline said.

The Mirror reports:

A similar issue happened last month, on June 1, when a flight from Canada to Texas turned into chaos when around 30 passengers fell ill with flu-like symptoms after a cruise trip they were on.

The passengers who fell sick onboard the Boeing 737 Max United Airlines flight were part of a larger group of about 75 people. It had taken off from Vancouver and landed at the Bush Intercontinental Airport in Houston where they met by emergency responders. At around 6:20 pm, the Houston Fire Department was called to assist at the scene.

According to United Airlines there were 163 passengers and six crew members on the flight. The plane has since been pulled from rotation while it undergoes a deep cleaning to disinfect and decontaminate it. In total, three passengers were looked at but none required further medical attention.

Officials from the fire department noted that the passengers exhibited symptoms linked to the cruise, complaining of nausea, and the airline confirmed the incident and said passengers from the cruise were ill and aboard the same flight.
