West 147th Street Friday at the apartment block where authorities were working to contain any threats from the infected Dr. Craig Spencer.

But even on the street and subway lanes he traveled, most New Yorkers just went straight back to work.

I 'm going about my normal day.

I don't think the average person, provided that you 're not working at the health care industry, it shouldn't be a concern.

There was some concern, inevitably.

Investigators say Dr. Spencer rode the one train in the days before he fell ill, and he went bowling in Brooklyn on Wednesday, the night before he reported symptoms.

Toward the A train station that Dr. Spencer had used to go downtown, some were unnerved that a disease that was continents away is now right next to people 's homes and workplaces in the city.

It's a disease and you can die.

They don't know whether they have a cure for it or every way you can protect yourself from getting it, so yes, I'm worried.

Staff at the station said the morning commute seemed like any other day.

On the L subway line that Dr. Spencer took to Williamsburg, travelers weren't blasé, but neither were they slathering themselves with hand sanitizer.

I 've seen people behaving as they normally do, if anything it's sort of a way of greeting people as a conversation starter like, " Oh, hey, did you hear about the Ebola thing?"

New Yorkers, I guess, are pretty thick-skinned.

Under the East River and off at the first stop, it was just a few minutes 's walk through gentrified Williamsburg to the Gutter bowling alley that was Dr. Spencer 's last stop on Wednesday night.

Some here said they had pangs of anxiety when the news first broke, but they soon passed.

I actually I was at Brooklyn Bowl last night.

A lot of people were talking about it, some people left.

I left and went and washed my hands for a minute straight because I just didn't know what else to do, but I think people are n't really freaking out around here.
