BALTIMORE, United States (AP) — A wide share of Americans are at least moderately confident in US health officials’ ability to handle emerging viruses, and more express concern about catching the flu than catching the new coronavirus, according to a poll from The Associated Press-NORC (AP-NORC) Center for Public Affairs Research.

The findings are encouraging to those banking on Americans’ trust in the health officials who are ordering quarantines and travel restrictions to contain the virus first detected in China.

“Our ability to control the virus hangs on people’s willingness to accept the advice of health authorities,” said Jennifer Nuzzo of the Johns Hopkins Center for Health Security in Baltimore. If the virus spreads more widely, public trust will become even more important, Nuzzo said.

News of the coronavirus outbreak is pervasive, with about half saying they have heard or read a lot about it. People who say they’ve heard a lot about the outbreak are more likely to say they’re very concerned about it than people who have heard less than that, but high levels of concern are still rare.

Like many Americans, Chris Harris of Iowa City is keeping up with the news, but is not worried about the new coronavirus. He’s more worried about influenza.

“I don’t want to miss work,” said Harris, a 51-year-old certified financial planner who’s had his annual flu shot. “I’d be out for a few days and it would put me farther behind.”

Comparable shares of Americans — roughly two in 10 — say they are very worried about getting the coronavirus and the flu.

Roughly another two in 10 say they are moderately worried about the coronavirus, but more than half of Americans say they are not concerned.

More have concerns about getting the flu: About four in 10 say they are moderately worried, while just about three in 10 say they are not.

That concern is appropriate considering US health officials estimate the nation has already seen at least 14,000 deaths from flu this season, said Janet Baseman of the University of Washington School of Public Health in Seattle.

“That’s a threat we have year after year,” Baseman said. In contrast, there have been 15 cases of the new virus in the United States, plus some Americans who were told they had it as they left a quarantined cruise ship in Japan. One US citizen died in China.

Concern about the coronavirus is roughly equal among Americans who have had a flu shot in the past year and those who have not, the poll found.

Sarah Burton, 57, of suburban Indianapolis got her flu shot this year. The environmental management consultant said she’s more worried about the flu than about the new virus and she feels confident the US health care system could handle an outbreak of a new pathogen.

“We’re fortunate in the country that we don’t have to panic about these things,” she said of the new virus. “We should be able to deal with this type of situation in this country with our massive resources.”

About a third of those polled have high confidence in officials’ ability to handle an outbreak, while about 4 in 10 are moderately confident. About two in 10 say they are not confident.

“All this potentially could change when we start finding more cases in the US,” said Nuzzo, the health security expert. “It will be different when they hear somebody in their community has the virus.”

That may happen.

The Centers for Disease Control and Prevention (CDC) is starting an effort to see if the virus is spreading silently. The CDC is adding coronavirus testing to the network that normally tracks flu. When a patient sample tests negative for flu, lab workers will check it for the new virus.

The extra tests will start in public health labs in five cities: Los Angeles, San Francisco, Seattle, Chicago and New York, then expand around the country.

As for Burton, she intends to stay informed about the new virus by reading three newspapers.

“The scary thing for me is they don’t know how to stop it yet,” Burton said.

The AP-NORC poll of 1,074 adults was conducted February 13-16 using a sample drawn from NORC’s probability-based AmeriSpeak Panel, which is designed to be representative of the US population. The margin of sampling error for all respondents is plus or minus 4.2 percentage points. Respondents were first selected randomly using address-based sampling methods and later were interviewed online or by phone.
