A medical team clad in Ebola protective suits boarded a US Airways flight amid fears a passenger was carrying the virus.
The drama unfolded on a plane at Punta Cana Airport in the Dominican Republic, which had arrived from Philadelphia.
The alarm was raised after a passenger reported overhearing another claim he was infected with the disease.
A flight attendant, addressing passengers before the medical team boarded the plane, said: “I’ve been doing this 36 years and I think the man that has said this is an idiot and I’ll say that straight out.”
The Dominican Ministry of Public Health later said the 54-year-old American passenger had no contact with Ebola patients or high-risk countries.
The drama on October 8 came after Thomas Eric Duncan, the first person to be diagnosed with Ebola within the US, died in Texas.
