2. 2020 started with the emergence of novel
   coronavirus known as SARS-CoV-2 that
   caused a pandemic of coronavirus disease
   (COVID-19) which causes respiratory and
   intestinal infections in humans.
   Human coronaviruses primarily cause
   respiratory infections. A number of strains
   of coronaviruses are recognized, most of
   which are responsible for the common
   cold.

3. Coronaviruses are enveloped,
   positive-sense single-stranded
   RNA viruses. They are members
   of the subfamily “Coronavirinae”
   (family; Coronaviridae,
   order; Nidovirales).
   Coronavirus contains four genera:
   1. alpha-coronavirus (e.g., 229E, NL63): infect
   mammals
   2. beta-coronavirus (e.g., SARS-CoV, SARS-CoV-
   2, HKU1, OC43, MERS-CoV): infect mammals
   3. gamma-coronavirus: infect birds
   4. delta-coronavirus: infect birds.

4. SARS-CoV
   In 2002, a new strain emerged in
   China that rapidly spread in the region,
   then to Hong Kong, Vietnam, and
   Singapore. Focal outbreaks were also
   reported in other countries by travelers
   from the endemic region who became ill
   when they returned home. The virus was
   named SARS-CoV. Two facts about this
   virus are critical: person-to-person spread
   occurred readily, including in the health
   care workers exposed to the patients, and
   the disease was responsible for a high
   mortality rate, particularly for patients
   with underlying pulmonary disease (i.e.,
   50% mortality) and in the elderly.

5. MERS-CoV
   In 2012, a new coronavirus infection
   erupted in the Middle East, again associated
   with a high mortality rate. This strain,
   MERS-CoV, has spread from the initial focus
   in the Kingdom of Saudi Arabia through the
   Middle East and to other countries via
   travelers. In contrast with the SARS-CoV
   strain, this coronavirus is only intermittently
   spread person-to-person; however,
   coronaviruses have a high mutation rate so
   this can change rapidly. In addition, the
   strain continues to circulate in the Middle
   East.

6. HOW DOES
   IT
   SPREAD?
   the main way of
   catching the disease
   is through the
   respiratory droplets
   expelled by sufferer
   while coughing or
   sneezing

11. Washing hands with
    soap and water kill
    viruses that may be on
    your hands.
    Maintain at least 1
    meter (3 feet) distance
    between yourself and
    anyone who is coughing
    and sneezing.

12. Cover mouth and nose with
    your bent elbow or tissue
    when you cough or sneeze.
    Then dispose off the used
    tissue immediately.
    Avoid touching eyes, nose
    and mouth with unwashed
    hands.
