This explains why COVID can attack various organs in our body and cause devastating effects.
Now the question remains, how is it that COVID kills some and not others? Why is it that some get the sniffles and others get pneumonia?

That answer is quite easy to answer. According to research published in the European Society of Clinical Microbiology and Infectious Diseases, it shows that the severity of sickness depends upon how many viral spores enters your nostrils at one given moment. This is why when you get tested for covid, they use a nasal swab. The virus enters your nose, and attaches itself to the ACE2 Ectoenzyme and it incubates and reproduces more spores, then it spreads by connecting to surrounding ACE2 Ectoenzymes. The spores that don’t connect are usually floating in your blood stream with nothing to connect to until it reaches another organ that has ACE2 ectoeymes. Then once it finds the ACE2 Ectoenzyme, it then starts the incubation process, multiplies and then spreads.

This is why scientist have asked us to wear face mask. The purpose of the facemask is to prevent or decrease the number of spores entering our nostrils. See, according to the research if you have one spore enter your nose, you probably will be asymptomatic. The more spores you have, the more severe your sickness will be.
