2.  Corona Virus (CoV) are large
family of viruses that cause
illness ranging from the
common cold to more severe
diseases. The first known
infections from SARS-CoV-2
were discovered in Wuhan,
China in December 2019.​
 The Corona Virus can
be spread from person to
person. It is
diagnosed with a laboratory
test.​

3.  Alpha (B.1.1.7)
 Beta (B.1.351)
 Gamma (P.1)
 Delta (B.1.617.2)
 Omicron (B.1.1.529)

4.  The SARS-CoV-2 Omicron
variant is a variant of SARS-CoV-
2, the virus that causes COVID-
19.
 The Variant was first reported to
the World Health Organization
(WHO) from South Africa on 24
November 2021
 On 26 November 2021, the WHO
designed it as a variant of concern
and named it after omicron.
 This level of variation has led to
concerns regarding
transmissibility, immune system
evasion and vaccine resistance.

5.  Corticosteroids and IL6
receptor blockers are
known to be effective for
managing patients with
severe COVID-19.
 The impact on the
effectiveness of other
treatments is currently
being assessed.

6.  The WHO is concerned that the large
number of mutations may reduce immunity
in people who were previously infected and
in vaccinated people.
 The WHO warns that health services could
be overwhelmed especially in nations with
low vaccination rates where mortality and
morbidity rates are likely to be much higher,
and urges all nations to increase COVID
vaccinations.
 Professor Paul Morgan, immunologist at
Cardiff University, also recommends
vaccination.
 The Virus can’t possibly lose every single
epitope on its surface, because if it did that
spike protein couldn’t work any more.

7.  Fatigue
 Body aches
 Cough
 Congested or
running nose
 Headache
 Night sweats

8. The best way to stay safe currently is by
following all WHO and Government
mandated safety measures for Omicron:-
 Get vaccinated if you haven’t.
 Maintain physical distancing.
 Limit your travel outside as much as
possible and avoid crowding at all cots.
 Wear a mask when stepping out or
meeting any outsider.
 Follow hand hygiene and respiratory
etiquettes.
 Do not ignore any signs of illness (Fever,
Weakness, Sore throat) and consult your
doctor immediately.

9.  Current PCR tests can detect the variant.
Some laboratories have indicated that a
widely used PCR test does not detect
one of the three target genes.
 Rapid antigen tests are most likely not
affected.
 Just as with the Alpha variant, this
partial detection(S” gene target failure”)
can serve as a marker for the variant.

10.  People infected with the
Omicron variant of
corona virus are between
50% to 70% less likely
to be admitted to the
hospital than who caught
earlier strains,
 According to a new UK
study that adds to a
growing body of
evidence of Omicron’s
reduced severity in
populations with high
levels of immunity.
