Flu symptoms can be very similar to those of the coronavirus, so Azar said his agency had rolled out an "early warning system" on Thursday, ordering coronavirus flu patients to be screened in five cities.
"We are using our influenza surveillance network in Seattle, San Francisco, LA, Chicago and New York, where people with flu-like symptoms or Chinese coronavirus will be tested not only for influenza but also for Chinese coronavirus", he told CNBC. "This way we have an early warning system. We have no epidemiological reason to believe that we have cases there, but we do want to be careful. "
Later today, the Centers for Disease Control and Prevention said the tests would not take place in hospitals but in samples sent to five public health labs in San Francisco, Los Angeles, Seattle and Chicago.
CDC spokesman Richard Quartarone said his agency will release more details on how the testing program will be deployed next week.
Azar also said his agency is closely monitoring the growing coronavirus epidemic in Singapore, where 67 cases have been confirmed.
"We access information hour by hour," he said when asked about the Singapore epidemic and possible travel restrictions. "We will take the necessary action if the data supports it. With Singapore, one of the questions is whether we are witnessing a true multi-generational spread of the community ... or if we are really seeing a first generation cluster that is really not that kind of multi-generational spread. We have to get to the bottom of it. "
