I. Coronaviruses and the Novel
    Coronavirus

                 What is the novel coronavirus?

     Coronaviruses are a large group of viruses. They are known to
cause diseases ranging from the common cold to more severe diseases
such as the Middle East respiratory syndrome (MERS) and severe
acute respiratory syndrome (SARS). The novel coronavirus (2019-
nCoV, later known as severe acute respiratory syndrome coronavirus
2 or SARS-COV-2) first identified in Wuhan, China, is a new type of
coronavirus that has not been found in humans before.

Does the novel coronavirus spread
                        from person to person?

          Yes. The virus mainly spreads via respiratory droplets and
    contact. There is a possibility of aerosol transmission in the case of
    long exposure to high concentration of aerosol containing the virus in
    a relatively closed environment. People are generally susceptible to
    the virus.

II. Coronavirus Disease

                Transmission of the disease

                                      People can get infected when they have close
                                      and direct contact with droplets or breath of
               Respiratory droplets   infected persons when they sneeze, cough or
                                      speak nearby.

                                      Infection can also be caused when one
                                      touches these droplets that have landed on
Transmission         Contact          objects and surfaces with their hands and
                                      then touches his/her mouth, nose, or eyes
                                      with contaminated hands.

                                      Aerosol transmission is also possible when
                Aerosol (possible)    one is exposed to high concentrations of
                                      aerosol in a relatively closed environment
                                      for a long time.

                                                            Coronavirus Disease       3
What are the symptoms of
                       COVID-19?

          According to the latest epidemiological studies, the incubation
    period for COVID-19 is 1–14 days, most commonly 3–7 days. Major
    symptoms include fever, dry cough and fatigue. Some patients may
    have nasal congestion, runny nose, sore throat, myalgia, or diarrhea.
    In severe cases, patients may develop difficulty breathing and/or
    hypoxemia around one week after the onset. Critical patients may see
    their symptoms progress rapidly to acute respiratory distress syndrome
    (ADRS), septic shock, refractory metabolic acidosis, coagulopathy,
    multi-organ failure, etc. It is worth noting that severe and critical
    patients may have had moderate to low fever, or even no fever at all.
    Their chest radiographs show multiple small shadowy patches and
    interstitial changes, especially visible in the extrapulmonary bands.
    Later, the patients develop multiple ground-glass opacities in both
    lungs. Severe cases suffer pulmonary consolidation while less pleural
    effusion. Mild cases may only have low fever and mild tiredness,
    without any sign of pneumonia.

What are close contacts?

     Close contacts refer to people who have had close and
unprotected contact (within one meter) with suspected or confirmed
cases two days before the onset or before the test in the case of
asymptotic infection. Specific situations are described as follows:
      1. People who live, study, work together with a suspected or
confirmed case, or a person with asymptotic infection, or have close
contacts in other ways such as working close to each other, sharing the
same classroom or living in the same housing space.
     2. Medical staff, family members, or other people who treat,
take care of, or visit a suspected or confirmed cases or a person
with asymptotic infection, or have had close contact in other similar
ways, such as paying a visit or staying with the person in a closed
environment; other patients in the same ward and their caregivers.
      3. People who share the same transportation vehicle and have
had close contact with a suspected or confirmed case, or a person with
asymptotic infection, including caregivers, peers (family, colleagues,
friends, etc.), or other passengers and flight attendants found likely
to have had close contact with the person through investigation
and evaluation. Depending on the means of transportation, specific
guidelines for determining close contacts are given as follows:
     (1) For civil aircraft, close contacts include:
      a) Under normal circumstances, passengers in the same row and
three rows in front of and three rows behind the infected person’s seat
in a civil aircraft cabin, as well as flight attendants who provide cabin
services in the area;

                                                       Coronavirus Disease   5
b) All passengers in the cabin of civil aircraft with no HEPA
    filter; and
          c) Others who are known to have had close contact with the
    infected person shall also be considered close contacts.
         Other passengers on a normal civil flight shall be regarded as
    general contacts.
          (2) For a railway passenger train, close contacts include:
         a) On a fully enclosed air-conditioned train, all passengers and
    crew members in the same hard-seat or hard-sleeper car, or in the
    same compartment on a soft-sleeper train, with the infected person;
          b) On a non-fully enclosed train, passengers in the same soft-
    sleeper compartment, or those in the same and adjacent compartments
    of a hard-seat or hard-sleeper car, and crew members serving the area;
    and
          c) Others who are known to have had close contact with the
    infected person.
         (3) For a car or bus, close contacts include:
         a) All passengers traveling in the same enclosed air-conditioned
    bus with the infected person;
          b) In the case of a ventilated bus, the driver, attendants and
    passengers in the three rows in front of and three rows behind the
    infected person’s seat; and
          c) Others who are known to have had close contact with the
    infected person.
         (4) For a cruise ship, close contacts include:
         a) All passengers in the same cabin as the infected person and
    crew attendants who provide services to that cabin; and
         b) Any people who have had contact with the infected person

6    Coronavirus Disease
when he/she is having severe symptoms such as a high fever, sneezes,
cough and vomit, regardless of the duration of the contact.
     4. Others who are classified as close contacts based on evaluation
by on-site investigators.
     In determining who are close contacts and analyzing possible
source of infection for an infected case, multiple factors shall be
taken into consideration, including the patient’s symptoms, the way of
contact with the patient, the protective measures during the interaction,
and the extent of exposure to contaminated environment and objects.

                  When to seek medical help?

      For adults who have generally been healthy, medical help is
recommended when they have symptoms such as fever, respiratory
infections, or acute gastrointestinal problems that are not relieved or
continue to progress after symptomatic treatment, or they develop
other suspicious symptoms such as shortness of breath, diarrhea,
or when family members also show symptoms that may indicate
COVID-19. Older people, pregnant women, and people who have
chronic conditions such as diabetes, immunodeficiency, hepatic and/
or renal insufficiency, and cardio-
cerebral vascular diseases are at
a higher risk of developing into
severe COVID-19 cases and they
should seek medical help upon the
onset of any suspicious symptom.

                                                      Coronavirus Disease   7
What to do if you suspect you are
                       infected?

         If you suspect that you are infected with the virus, that is, if you
    have suspicious symptoms (including fever, dry cough, fatigue, nasal
    congestion, runny nose, sore throat, myalgia, and diarrhea), avoid
    crowds, wear a face mask, isolate yourself, keep distance from your
    family members, ensure good ventilation and personal hygiene, and
    go to a nearby fever clinic of a designated hospital for COVID-19
    cases as soon as possible. When seeing a doctor at the clinic, tell the
    doctor whom you have been in contact with and be cooperative for the
    necessary investigation.

III. Effective Prevention and
      Treatment

                 Is there a cure for COVID-19?

     Based on available information and experience accumulated so
far, the disease has a good prognosis and can be cured. A small number
of patients can become critically ill, though. Prognosis tends to be
poor for the elderly and those with chronic underlying diseases, while
children usually show relatively mild symptoms.

Medical observation at home for
                  close contacts

     Those who are defined as close contacts of a confirmed
COVID-19 case should stay home for 14 days of medical observation
starting from the day of their last contact with the confirmed case or
person with asymptomatic infection. They need to keep in touch with
healthcare workers in the process and be informed of the key points of
the observation, self-care and preventive measures such as hand wash,
ventilation, protection, and disinfection. Specific recommendations are
as follows:

     1. Close contacts should stay in a well-ventilated single room
and receive no visitor.

     2. Reduce activities and minimize the areas they share with
family members. Keep all shared spaces (e.g. kitchen, bathroom, etc.)
well ventilated (e.g. by keeping windows open).

     3. Do not share a room with any family member. If this is
impossible, always keep a distance of at least one meter. Breastfeeding
may continue.

     4. Family members should wear a surgical mask that fits tightly
when entering the living space of the close contact. Avoid touching
and adjusting the mask before getting out of the space. Replace the
mask immediately when it gets wet or contaminated. Wash hands
thoroughly after removing and disposing of the mask.

     may either wash the hands with soap and running water, or use alcohol
     hand sanitizer. (Note: Use alcohol cautiously to avoid accidental
     swallowing or fire).

          6. After washing your hands with soap under running water, use
     disposable paper towels to dry the hands. If not available, wipe with a
     clean towel and replace it when it gets wet.

          7. Materials used to cover the nose and mouth for occasional
     cough or sneezes should be discarded immediately, or cleaned properly
     after use (e.g. washing with soap/detergent and water).

          8. Family members should minimize contact with the close
     contact and his/her personal items. For example, avoid sharing
                                           toothbrushes, cigarettes, utensils,
                                           meals, drinks, towels, bath towels,
                                           sheets, etc. Dining utensils should be
                                           cleaned with steam sterilization after

     the same. The elderly and children should take protective measures,
     such as washing their hands frequently, wearing face masks, having
     balanced and nutritious diet, exercising moderately, keeping their
     living environment clean, and maintaining good ventilation for their
     homes.

                         Disinfection measures for homes
                         with COVID-19 patients

          After the patient leaves (hospitalization, death or release from
     isolation, etc.), terminal disinfection should be performed in the
     home, including the living room floor, walls, surfaces of tables, chairs
     and other furniture, door handles, the patient’s utensils, clothing
     and bedding and other daily items, toys, bathroom, etc. Terminal
     disinfection is usually done by professionals, please contact your
     local center for disease control and prevention. Family members of a
     confirmed patient are usually identified as close contacts and should
     undergo medial observation for 14 days.

                         Are antibiotics effective for
                         COVID-19?

          Antibiotics are used to treat bacterial infections. COVID-19
     has a virus as its pathogen and antibiotics are not effective either for
     prevention or treatment. Taking antibiotics may even cause adverse
     drug reactions and destroy the normal intestinal flora.

How to dispose of a used face mask
                   properly?

     Face masks worn by uninfected people do not have the risk of
spreading the coronavirus and can be disposed of following general
requirements of domestic waste classification. Face masks used by
suspected cases and their caregivers should be collected and disposed
of as medical waste. After disposing of such face masks, be sure to
wash your hands.
