#SARSCoV2 from transmission
to disease
:
1. Spike protein on the virus binds the ACE2 receptor on human cells. The Virus RNA is released into the cell, where it is translated into proteins that assemble and make-up new virus particles that are then sent back out of the cell

2. #SARSCoV2 comes out of the respiratory tract
on small aerosols that stay airborne and are then inhaled; on bigger respiratory droplets
that splash into others' nose/mouth/eyes or they land on surfaces and get picked up by touch; the virus is also excreted through human waste


3. #COVID affects many of the body's systems—upper and lower respiratory tract
; heart
, where it can cause arrhythmias & other problems; digestive problems like nausea, pain, vomiting; neurological
problems where people suffer cognitive challenges even after recovery & more.



4. When virus is inhaled & lodged deep into lungs it can cause a lot of damage. It gets inside airway cells & other cell types where it damages/kills them. It can also cause immune system cells (Macrophage/Neutrophils) to go haywire, further damaging lungs
respiratory failure.

5. There is so much we still don't know about #COVID19. Please take precaution, physical distance, wear a mask
, ventilate indoor spaces
, and practice good hygiene. https://www.cell.com/trends/immunology/fulltext/S1471-4906(20)30233-7?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS1471490620302337%3Fshowall%3Dtrue
