5. Infection Progress
Virus Multiplies and victim shed
copious amount.
Symptoms like Fever, dry
cough, sore throat, loss of smell
and taste, or head and body
aches OR patient may be
asymptomatic
SARS-CoV-2
Enters through
NOSE/THROAT
New Findings
WBC target and
kill virus-
infected cells,
leaving a stew
of fluid and
dead cells—
pus—behind.
Patient land up on
ventilator and death
Virus need this to enter
the cell
The virus then marches
down the windpipe to
attack the lungs, and
reaches ALVEOLI, where
Oxygen exchange takes
place.(Rich in ACE2)
Alveoli became stuffed
with fluid, white blood cells,
mucus, and the detritus of
destroyed lung cells.
SARS-CoV2
itself or body
response to it is
damaging other
organs as well.
Angiotensin-
Converting
EnzymeReceptor2
If Immunity is
low
Some patients
Deteriorates
to develop
ARDS
Virus hijacked
the cell and
multiplies itself.
White blood cells release
inflammatory molecules
called Chemokines
Severity of
SARS-CoV2
COVID 19
7. LUNGS
An inflamed alveolus, or
air sac, whose walls
break down during attack
by the virus, diminishing
oxygen uptake. Patients
cough, fevers rise, and
breathing becomes
labored.
ORGANS AFFECTED BY CORONAVIRUS
BRAIN
Some COVID-19 patients have strokes,
seizures, confusion, and brain
inflammation. Doctors are trying to
understand which are directly caused by
the virus.
8. INFECTED LUNGS BY CORONAVIRUS
DAMAGED LUNGS
OF DEAD PATIENT,
SEEN AS YELLOW
COLOR
9. EYES
Conjunctivitis, inflammation of the
membrane that lines the front of
the eye and inner eyelid, is more
common in the sickest patients
NOSE
Some patients lose their sense of
smell. Scientists speculate that the
virus may move up the nose’s
nerve endings and damage cells
ORGANS AFFECTED BY CORONAVIRUS
10. HEART & BLOOD VESSELS
The virus enters cells, likely including
those lining blood vessels, by binding
to angiotensin-converting enzyme 2
(ACE2) receptors on the cell surface.
Infection can also promote blood clots,
heart attacks, and cardiac
inflammation
LIVER
Up to half of hospitalized patients
have enzyme levels that signal a
struggling liver. An immune system
in overdrive and drugs given to
fight the virus may be causing the
damage.
ORGANS AFFECTED BY CORONAVIRUS
11. KIDNEYS
Kidney damage is common in severe
cases and makes death more likely.
The virus may attack the kidneys
directly, or kidney failure may be part
of whole-body events like plummeting
blood pressure
INTESTINES
Patient reports and biopsy data
suggest the virus can infect the
lower gastrointestinal tract, which
is rich in ACE2 receptors. Some
20% or more of patients have
diarrhea
