How to wearmask
Here’s what COVID-19 does to yourbody.
 Infection – Virus enters the body – generally through the mouth or nose. From there, the virus makes its
way down into the air sacs inside your lungs, known as alveoli. Once in the alveoli, the virus uses its
distinctive spike proteins to “hijack” cells. The primary genetic programming of any virus is to make copies of
itself, and COVID-19 is no exception. Once the virus’ RNA has entered a cell, new copies are made and the
cell is killed in the process, releasing new viruses to infect neighbouring cells in the alveolus.
 Immune Response – The process of hijacking cells to reproduce causes inflammation in the lungs, which
triggers an immune response. As this process unfolds, fluid begins to accumulate in the alveoli, causing a
dry cough and making breathing difficult.
 Severe Symptoms - the immune system’s response to inflammation in the lungs can cause what’s known as
a “cytokine
storm”. This runaway response can cause more damage to the body’s own cells than to the virus it’s trying to
defeat, and is thought to be the main reason for why the conditions of a patient to be placed on a ventilator
for breathing assistance. Both acute respiratory distress syndrome (ARDS) and high-altitude pulmonary
edema (HAPE) are being investigated as causes.
1.Headache.
2.fever.
3.Cough or sore throat.
4. Runny Nose.
5.Breathing difficulties.
6.Anosmia – Smelling sense lost.
7. Diarrhea.
8.Pneumonia.
9.Kidney Failure.
