New Yorkers seemed to take news of the city's first case of Ebola in stride Friday by going about business as usual.
The infected patient, Dr. Craig Spencer, is known to have traveled on at least three subway lines after returning from West Africa, where he treated Ebola patients as a volunteer with Doctors Without Borders.
Friday morning, subway ridership was at normal levels, the Metropolitan Transportation Authority told CNBC. The system handles an average 5.8 million riders a day. Traffic on Metro-North lines, which shuttle about 280,000 commuters daily into the city from upstate and Connecticut, also remained normal.
"The MTA New York City Subway system is safe to ride. The person diagnosed with Ebola in New York City rode the subway several times since returning from abroad, but the state and city health commissioners agree there was no risk to any other subway customers or any MTA employees," the MTA said in a statement.
Ebola cannot be spread by casual contact and is not contagious until symptoms appear, health officials say.
The authority noted that the virus cannot live for more than a few hours on hard surfaces. It also said it had issued protective gloves to employees and instructed staff to use 10 percent bleach solution to disinfect trains and double bag any potential infectious waste.
Spencer also rode in a hired car that he booked through ride-sharing service Uber on Wednesday evening. Uber, which is known for tracking ridership in real time, did not respond to multiple requests for comment on whether ridership on its New York City network had dipped.
In a statement Thursday, the company said the New York City Department of Health and Mental Hygiene determined that the driver of Spencer's car and subsequent passengers were not at risk.
