Coronavirus exposure no longer means automatic 14-day isolation, Sacramento
County says
Sacramento County announced Monday that its public health department will no
longer recommend isolation or quarantine for people exposed to someone with
COVID-19, making a pivot from a strategy of containment to one of
mitigation.
In an interview, Dr. Peter Beilenson, head of the county’s Department of
Health Services, said public health officials had quarantined the sick and
those who came into close contact with them as a way to slow spread of the
disease.
“Once you get a certain number of cases, it’s hard to continue to contact-
trace back the way you tried originally,” Beilenson said, “so we move to
mitigation, which is basically trying to mitigate the risk to those who are
most at risk: the elderly and those with chronic underlying conditions.”
Because the new coronavirus poses the greatest threat to these individuals,
he said, they and their families must take precautions to avoid exposure. If
AARP is having a gathering, for example, the health department might
recommend that people in their 70s or 80s not attend. If children are
showing symptoms of COVID-19 — fever, coughing, shortness of breath —
their parents should avoid taking them to visit grandparents either in their
homes or at an assisted living facility, he said.
Although Sacramento is making this announcement today, Beilenson said, he
expects other counties around the state will announce plans to do the same
soon.
SHIFT MAKES SENSE, EXPERT SAYS
Epidemiologist Catherine Troisi of the University of Texas Health Science
Center at Houston said this change in strategy may be risky from a public
perception standpoint because of the level of fear about this new illness.
However, she said, this shift makes a lot of sense to her as an infectious
disease researcher.
“I’ve been saying for a week that we cannot contain the virus. It’s time
to move to mitigation,” Troisi said. “I don’t want to say we’ve lost the
battle because that implies we could have won it, and this is an infectious
virus, and due to a lot of circumstances, the odds of us being able to
contain that were very small. China bought us some time. Unfortunately in
the United States, we didn’t take advantage of that time. We had problems
with the testing kits.”
COVID-19 is spreading fairly significantly around the United States,
Beilenson said. While public health officials had confirmed roughly 700
cases of COVID-19 across the country as of Monday evening, Cedars-Sinai
researchers estimated that more than 9,000 people in the United States
already had been infected with the new coronavirus by March 1.
“This suggests that the opportunity window to contain the epidemic of COVID
-19 in its early stage is closing,” the researchers stated in their paper,
which is posted online on a forum where physicians and researchers share
information.
The Cedars-Sinai investigators said they used “very conservative” methods
to make their estimates, so they likely underestimated the number of cases.
Their study modeled only COVID-19 coronavirus cases that could have been “
imported” directly to the U.S. from Wuhan, China, before Jan. 23, when the
Chinese government locked down the city. They assumed the lockdown stopped
all outbound traffic from the city, which was the epicenter of the new
coronavirus outbreak.
Beilenson said scientists have had the opportunity to study COVID-19 and
have found that 80-plus percent of those infected are not symptomatic or
have only mild symptoms. In addition, he said, it appears that people who
have the disease gain an immunity to it. Medical researchers differ on how
long that immunity will last. Some say a season, while others say it could
be effective for next season.
That immunity, however, could buy time for researchers to develop a vaccine,
a process that experts say will take at least a year.
WHEN TO SEEK EMERGENCY CARE
Until then, Beilenson said, there is no need for the general public, health
care workers or first responders to isolate themselves after an exposure.
They should stay home only if they develop symptoms, he said, and call 911
for assistance only if they are extremely sick or believe their lives are in
imminent danger.
Dr. Theresa Cheng, a senior resident who works at several hospitals in
California, said that, as an emergency room physician, she is seeing people
on both ends of the spectrum coming in seeking advice on COVID-19 and other
respiratory illnesses. There definitely has been an upswing in asymptomatic
people in ERs asking to be tested for the coronavirus, she said, and there
are also people who have underlying health conditions who should have sought
care earlier.
“If you’re feeling fine, if you’re otherwise well, then the best thing
you can do is put on a mask to prevent the transmission of those little
droplets to other people, those around you,” she said. “It’s those people
who have those comorbidities who are at higher risk. They should come in,
or if they’re experiencing severe symptoms, they should definitely come in.”
If people have symptoms that get better and then grow worse, Beilenson said,
they should call ahead for care with their health care provider or an
urgent care center. People who have mild symptoms can treat themselves at
home with over-the-counter medications.
If you are in a high-risk group, Beilenson said, consider avoiding crowded
social gatherings where you cannot put at least two arms’ length worse of
space between you and others. And although the CDC recommends face masks
only for those who have COVID-19 and their caregivers, Beilenson said that
some physicians may recommend that immuno-compromised patients wear them
when out shopping for groceries or running other errands.
“If you can, go to the store and do two or three weeks’ worth of shopping
at one time,” he said. “That makes a lot of sense. And try to go in off-
peak hours.”
Public health officials recommend that companies give employees the option
to telecommute from home or teleconference with other workers because people
may still be able to work with mild cases of the illness. If schools have a
COVID-19 exposure, Beilenson urged them to collaborate closely with their
local health department and County Office of Education to determine
appropriate steps to take. | k**0
