LONDON (KRON) – Eight planes, including one from San Francisco, were placed on lockdown at Heathrow Airport due to coronavirus fears, according to the DailyMail.

The lockdown was placed after passengers on board complained of symptoms of the deadly virus.

The DailyMail reports that travelers on the United Airlines Flight 901 from San Francisco were told by the captain to stay in their seats after landing because someone might have the contagious infection.

United Airlines confirmed that someone had ‘become unwell’ on board on the San Francisco flight. The airline followed CDC protocol and gave the plane a deep cleaning, which includes cleaning all surface areas and overhead bins, after passengers were gone.

Crews have received additional special guidance on CDC procedures and have direct access to trained medical professionals on the ground who provide guidance on courses of action.

A witness reported that a passenger was removed from the back of the plane.

Everyone else was allowed to get off of the plane about a half hour later.

Public Health England and Heathrow officials have not yet released any information about this morning’s incident.
