Per CNN:

The 25 sickened passengers who complained of nausea on Flight 1528 on Friday were among a group of 75 people that had previously traveled on a cruise in Vancouver, according to the Houston Fire Department.

United Airlines did not say what cruise the passengers were on prior to Friday’s flight, which carried 163 passengers and six crew members.

The travelers aboard the Boeing 737 Max 8 that arrived in Houston shortly after 6 p.m. CT were ill “due to the cruise,” Martee Black, a spokesperson for the Houston Fire Department, told CNN.

The Houston Fire Department arrived at George Bush Intercontinental Airport and evacuated three patients from the plane but no one was transported to the emergency room, Black said.

United Airlines said it would deep clean the aircraft before returning it to service “as a precautionary measure.”

“United Airlines is actively coordinating with health authorities to address the situation,” the airline said in a statement.

Fox Business reports:

The Centers for Disease Control and Prevention (CDC) told Fox Business that most of the sick passengers had “GI symptoms.”

While the exact illness has not been reported, United Airlines explained to Fox News Digital that 75 of the flight's passengers were returning from a cruise.

“Several passengers who had been on the same cruise and did not feel well were on United Flight 1528 from Vancouver to Houston,” a United Airlines spokesperson explained. “United Airlines is actively coordinating with health authorities to address the situation.”

The aircraft then went through a deep cleaning after the passengers deplaned.

“Public health officers from CDC’s Houston Port Health Station worked with EMS to evaluate ill passengers on board,” a CDC spokesperson told Fox Business.
