Las Vegas state officials temporarily quarantined a commercial flight plane on Friday because of global fears that the deadly Ebola virus will spread outside West Africa, a move which led to the dip in the airline shares.

The Delta Air Lines plane was quarantined by authorities at the McCarran International Airport because of the Ebola threat, but according to airline and medical officials, it was only a false alarm, and the plane was given the green light to fly.

An airline spokesman said passengers started showing concerns after one passenger from the John F. Kennedy International Airport in New York started feeling sick.

The Las Vegas incident was the latest Ebola-related scare involving an aircraft within the week, which was covered by the press, following Wednesday's incident wherein a U.S. Airways flight passenger claimed to have been infected by the virus.

Dominican Republic officials investigated the U.S. Airways flight from Philadelphia, and cleared the plane after concluding that there was no threat on the aircraft.

A passenger video released by the media showed authorities wearing blue protective gear went onboard the plane and escorted a man off.

Also on Wednesday, an American Airlines commercial plane emergency landed in Texas after a female passenger vomited during the flight.

Meanwhile on Saturday, medical authorities escorted passengers off a plane in Newark, New Jersey, after a Liberian man and his daughter started exhibiting symptoms of Ebola.

Because of the growing concern and anxiety of people about contracting the virus, medical and health officials are worried that there might not be sufficient resources for people's needs.

According to a study conducted by the U.S. Centers for Disease Control and Prevention in September, as many as 1.4 million people could be infected by the virus in West Africa by January.

Meanwhile, the Delta Airline stocks fell by 1.7 percent following the Las Vegas Ebola scare.

Stocks of other airlines also fell after the Vegas incident: United Continental Holdings fell by 2.5 percent while the Southwest Airlines lost 1.8 percent.
