What is
the Coronavirus?
- 2019 Novel Coronavirus (2019-nCoV) is a virus
(more specifically, a coronavirus) identified as the cause of an outbreak
of respiratory illness first detected in Wuhan, China.
- Early on, many of the patients in the outbreak
in Wuhan, China reportedly had some link to a large seafood and animal
market, suggesting animal-to-person spread.
- However, a growing number of patients
reportedly have not had exposure to animal markets, indicating
person-to-person spread is occurring.
- The name coronavirus is derived from the Latin
corona, meaning "crown" or "halo", which refers to the
characteristic appearance reminiscent of a crown.

How do you get
infected?
- The main route of transmission is respiratory
droplets and close contact.
- When you sneeze or cough, you send out
droplets of fluid from your nose and mouth.
- Those droplets can carry infections, and when
they enter someone else's enter the eyes, nose or mouth, the infection can
make them sick. This is the way the flu and many viruses are spread.
- Most often, you need to be close to the person
(within 6 feet) for it to spread this way.
- There is the possibility of aerosol
transmission when exposed to high concentration aerosol for a long time in
a relatively closed environment.
- The WHO has stated that the risk of spread
from someone without symptoms is "very low" and that fecal
transmission is "low".
How can I
protect myself?
Handwashing
- A number of governments advise against all
non-essential travel to countries and areas affected by the outbreak.
- There are misconceptions circulating about how
to prevent infection: rinsing the nose, gargling with mouthwash, and
eating garlic are not effective.
- The CDC recommends that people wash hands
often with soap and water for at least 20 seconds, especially after going
to the toilet or when hands are visibly dirty.
- It further recommended
using an alcohol-based hand sanitiser with at least 60% alcohol by volume
(or 120 proof) when soap and water are not readily available.
- The WHO also advise
people to avoid touching the eyes, nose, or mouth with unwashed hands.
Respiratory
hygiene
- Health organizations recommended that people
cover their mouth and nose with a tissue when coughing or sneezing (which
should then be disposed of immediately), or with a sleeve if a tissue is
not available.
- The use of surgical masks by those who may be
infected has also been recommended, as they can limit the volume and
travel distance of expiratory droplets dispersed when talking, sneezing,
and coughing.
- There is no evidence to show that the wearing
of surgical masks by uninfected people at low risk is effective.
- Only China has specifically recommended the
use of masks by healthy members of the public, while face masks have been
widely used by healthy people in Hong Kong, Japan, Malaysia, and
Singapore.
How do I know if I am
infected?
Common signs of
infection include respiratory symptoms, fever, cough, shortness of breath and
breathing difficulties. In more severe cases, infection can cause pneumonia,
severe acute respiratory syndrome, kidney failure and even death.

How to use a
mask
- Wear a mask if you are coughing or sneezing.
- If you wear a mask, then you must know how to
use it and dispose of it properly.
- Before putting on a mask, clean your hands
with alcohol-based hand rub or soap and water.
- Cover your mouth and nose with the mask and
make sure there are no gaps between your face and the mask.
- Avoid touching the mask while using it.
- Replace the mask with a new one as soon as it
is damp and do not re-use single-use masks.
- To remove the mask, remove it from behind (do
not touch the front of the mask), discard it immediately in a closed bin,
and then clean your hands with alcohol-based hand rub or soap and water.

Ok I think I'm
infected, now what?
- Self-isolation at home has been recommended
for those diagnosed with COVID-19 and those who suspect they have been
infected.
- Public health agencies have issued
self-isolation instructions that include notification of healthcare
providers by phone and restricting all activities outside of the home,
except for getting medical care.
- Do not go to work, school, or public areas.
Avoid using public transportation, ride-sharing, or taxis
- Those who have recently travelled to a country
with widespread transmission or who have been in direct contact with
someone diagnosed with COVID-19 have also been asked by some government
health agencies to self-quarantine or practise social distancing for 14
days from the time of last possible exposure.
- Attempts to relieve the symptoms may include
taking regular (over-the-counter) cold medications, drinking fluids, and
resting. Depending on the severity, oxygen therapy, intravenous fluids,
and breathing support may be required.
- The use of steroids may worsen outcomes.
Is there a
vaccine or a cure?
- No vaccine is currently available.
- Several organisations around the world are
developing vaccines, using several different methods.
- By early March 2020, 30 vaccine candidates
were in development, with products by Gilead Sciences and Ascletis Pharma
in Phase III clinical trials.
- Several compounds, which were previously
approved for treatment of other viral diseases, such as favipiravir,
ribavirin, remdesivir and galidesivir, are being investigated against the
coronavirus.
- Clinical trials are underway in for
lopinavir/ritonavir and of remdesivir.
- Bruce Aylward, an assistant director-general
of the WHO, has stated "there is only one drug right now that we
think may have real efficacy and that's remdesivir."
