Loss of smell, taste, might signal pandemic virus infection
Posted Mar 25, 2020 7:00 AM
NEW YORK (AP) — A loss of smell or taste might be an early sign of infection with the pandemic virus, say medical experts who cite reports from several countries.
It might even serve as a useful screening tool, they say.
The idea of a virus infection reducing sense of smell is not new. Respiratory viral infection is a common cause of loss of smell, because inflammation can interfere with airflow and the ability to detect odors. The sense of smell usually returns when the infection resolves, but in a small percentage of cases, smell loss can persist after other symptoms disappear. In some cases, it is permanent.
Now, there’s “good evidence” from South Korea, China and Italy for loss or impairment of smell in infected people, says a joint statement from the presidents of the British Rhinological Society and of ENT UK, a British group that represents ear, nose and throat doctors. In South Korea, some 30% of people who tested positive for the virus have cited loss of smell as their major complaint in otherwise mild cases, they wrote.
So that might be useful as a way to spot infected people without other symptoms — fever, coughing and shortness of breath — of the new coronavirus, they wrote.
A similar proposal was published Sunday by the American Academy of Otolaryngology-Head and Neck Surgery. It noted “rapidly accumulating” anecdotal evidence from around the world that the pandemic virus can cause not only loss of smell but also a diminished sense of taste. So the appearance of those symptoms in people without another explanation should alert doctors to the possibility of a COVID-19 infection, the group said.
Maria Van Kerkhove, an outbreak expert at the World Health Organization, told reporters Monday that the U.N. health agency is looking into the question of whether the loss of smell or taste are a defining feature of the disease.
Dr. Eric Holbrook, an expert on nasal and sinus disease at the Massachusetts Eye and Ear hospital in Boston, said the reports have been a hot topic among researchers and doctors. But “we don’t have hard evidence right now” about how often smell loss occurs in people infected with the pandemic virus, he said in an interview Monday.
Holbrook said the reports he has seen suggest the sense of smell returns within a couple weeks, but how long it lasts has yet to be firmly established.
He also said it’s difficult to assess reports of a loss of taste because people with an impaired sense of smell often report a loss of flavor, which is technically different from an impairment in taste.
Holbrook said he is trying to set up a study of smell in people being tested for the coronavirus at Boston-area hospitals.
The new coronavirus is spreading quickly around the world, including across Kansas, and setting off a range of responses.

CASES AND DEATHS
900 cases (see map for counties) and 223 hospitalizations
27 deaths (the state is no longer disclosing which counties are seeing deaths)
NOTE: These figures only
include cases confirmed with lab tests and do not represent the real,

Gov. Laura Kelly is instituting a statewide stay-at-home order as of
12:01 a.m. March 30. It will last until at least April 19. Stay-at-home
orders allow people to take care of essential activities (such as
grocery shopping or going to work) as well as exercise outside, but
otherwise keep to themselves.
The state’s stay-at-home order
supersedes at least 13 county-by-county orders. Should the state’s order
lift before a county’s is through, the county can choose to keep its
own in effect.
SHOULD I SELF-QUARANTINE?
The Kansas Department of Health and Environment (KDHE) is now mandating home
quarantine for 14 days if you've traveled to the places listed below.
If you come down with symptoms (such as a fever of 100.4 degrees or
higher, coughing or shortness of breath) during those 14 days, contact
your health care provider and explain your potential COVID-19
Connecticut on or after April 6.
Louisiana or anywhere in Colorado on or after March 27.
States with known widespread community transmission (California, Florida, New York and Washington) on or after March 15.
Illinois or New Jersey on or after March 23.
Eagle, Summit, Pitkin and Gunnison counties in Colorado (if your visit was March 8th or later).
ships or river cruises on or after March 15. Anyone previously told to
quarantine because of their cruise ship travel should also finish out
International destinations on or after March
15. Anyone previously told to quarantine because of their international
travel should also finish out their quarantine.
doctors recommend patients with COVID-19 symptoms stay home even if they
test negative for the disease, because of concerns that current testing
approaches may be producing a significant number of false negatives.
hospitals across the state now offer drive-through testing, but
patients must get doctor approval in advance or else will be turned
away. Many Kansans can’t be tested unless they’re sick enough to be
hospitalized, and results may take up to a week.
testing supplies remain limited and private labs helping many clinics
and hospitals have large backlogs of samples. Hospitals trying to buy
equipment for in-house testing say vendors are backlogged, too. The
state will soon have several portable machines that can conduct 5- to
15-minute tests, and plans to lend them out to facilities most in need.
Some Kansas hospitals have succeeded
in getting the testing materials and can give patients their results
within a day. The state health department lab in Topeka can handle
several hundred samples per day — a fraction of the demand.
Under a new federal law, you should not have to pay for your coronavirus test, regardless of insurance status (but patients could still see related bills).
Separately, Blue Cross Blue Shield of Kansas, the state’s largest
private insurer, says some patients won’t have to pay for coronavirus
HOW ARE UNIVERSITIES RESPONDING?
and private universities and community colleges in the state will
finish this semester via online classes. Spring sports have been
canceled. Most staff travel has been suspended. Graduations at KU,
K-State and Wichita State are postponed or rescheduled.
University of Kansas and Wichita State also plan to hold summer classes
online. KU and K-State announced hiring freezes in early April.
HOW ABOUT K-12 SCHOOLS?
In mid-March, Kansas became the first state in the U.S. to shut down school buildings for the rest of the 2019-20 school year. A state task force then issued guidance for distance learning, for which students aren’t expected to spend more than a few hours a day.
Some districts that make high schoolers earn more credits than required by the state will graduate them this year based on the state’s lower bar.
Districts across the state are still providing free meals to eligible children, but some have stopped because of concerns about the coronavirus spreading at meal pickup sites.
WHAT IN DAY-TO-DAY LIFE IS AFFECTED?
Church gatherings and funerals:
Effective April 8, the governor has prohibited services of more than 10
people. That doesn’t count people performing the rituals or funeral
workers, but they must stay six feet apart from each other.
State tax deadline: Extended until July 15, in line with a delay for filing federal tax forms.
Evictions: Business and residential evictions are banned until May 1 if a tenant is unable to pay because of the coronavirus.
Mortgage foreclosures: Foreclosures are banned until May 1.
Small businesses: May be eligible for emergency federal loans. Find information here.
Hospitality businesses: Kansas created an emergency loan program, which quickly ran out of funds, but businesses can still apply to help the state assess the need for more assistance.
which serves 950,000 customers in Kansas, will not disconnect
residential or business services for an unspecified amount of time.
Gatherings: Restricted to fewer than 10 people throughout the state.
State of emergency: Kansas’
declaration is good through May (and can be extended). It gives the
government more power to marshal resources and Kelly the ability to make
certain decisions when lawmakers aren’t in session.
State workers: Access
to the Statehouse is limited to official business only through April
19. Most state workers are doing their jobs remotely.
Prisons and jails: The
Kansas Department of Corrections ended visitation at all state
facilities, and will “re-evaluate on an ongoing basis.” It urges
families to talk to inmates through email, phone calls and video visits.
County jails largely have ended visitations as well.
HOW BAD IS THE VIRUS?
usually causes mild to moderate symptoms, like a fever or cough. Most
people with mild symptoms recover in two weeks. More severe cases, found
in older adults and people with health issues, can have up to six
weeks’ recovery time or can lead to death.
