Leading health experts warned on Feb. 12 that the United States could see thousands of cases of the new coronavirus, or COVID-19, and a significant surge in the spread of the virus in the coming weeks.
“I don’t think we should be planning for the onesie-twosie cases that we’ve been seeing thus far in the United States,” George said. “We have to plan for the possibility that we have thousands of cases.”
George, one of five panelists, warned of a large scale outbreak nationwide.
There has been no sign of sustained human-to-human transmission among known cases of the virus in the United States so far.
Another evacuee at Air Station Miramar tested positive for the virus on Feb. 10.
But Scott Gottlieb, a former Food and Drug Administration commissioner, told the Senate committee that he expects a COVID-19 outbreak to emerge across the United States in the next two to four weeks.
“We should be leaning in very aggressively to try to broaden diagnostic screening right now, particularly in communities where there is a lot of immigration; where these efforts could emerge to identify them early enough; that they'll be small enough; that we can intervene to prevent more epidemic spread in this country,” he said.
Gottlieb said that despite efforts from U.S. customs officials to suspend travel between the United States and mainland China and Hong Kong, as well as screen those who had returned from Wuhan—the Chinese city at the epicenter of the outbreak—some people infected with COVID-19 would still have entered the United States.
A former director of the Centers for Disease Control and Prevention (CDC), Julie Gerberding, added that the United States can expect more cases among people who did not travel to China but have been infected by those who had visited the region before the travel bans were implemented.
Gottlieb said that it is likely that health screenings in airports missed infected travelers due to the extensive incubation period of the disease.
“Some of the modeling out of the UK suggests that we’re capturing about 25 percent of cases at best. So for every case we identify, there’s three or four that we didn’t identify.”
Coronavirus Spread Must Be Slowed
Gerberding added that the United States must work to slow down the spread of COVID-19, saying that she is worried about the prospects of successful long-term containment of the disease.“If we can’t contain it, I think we need to be prepared for what are we going to do to try to slow down the spread,“ she told the Senate committee. ”Slowing down spread is important, because if we have a lot of cases all at once, we simply don’t have the surge capacity to manage that in our healthcare environment, or in any of the related services that would be necessary.”
In order to slow down the spread, those infected must be identified and isolated in places where they can’t infect others, and isolation materials such as gloves and masks should be readily available, she said.
Another measure to slow down the spread of the virus can involve steering clear of large crowds to prevent person-to-person and droplet transmission of the virus.
Gerberding explained that while these measures alone are not likely to prevent all spread in the community, they can act as an effective barrier until countermeasures are put in place.
American Airlines and United Airlines have both extended their suspension of flights between the United States and mainland China and Hong Kong until late April as the World Health Organization (WHO) warned of a global threat potentially worse than terrorism.
WHO director-general, Tedros Adhanom Ghebreyesus, said during a Tuesday news conference that the world must “wake up and consider this enemy virus as public enemy number one,” adding that the first vaccine was most likely 18 months away.
