When we incubated the HIV virus, its Infectivity was dramatically reduced by the rabbit's blood.”.
Its Infectivity is exemplified by the fact that an individual inoculated
with only 57 organisms has a 50% chance of being infected.
While lepromatous leprosy in which bacteria are high and Infectivity is also high,
it can be cured with at least one year of‘Multi-Diving Therapy‘(M.D.T.).
It is possible, similar to SARS-CoV,
that SARS-CoV-2 might become weaker in Infectivity and eventually die down
or become a less pathogenic virus co-existent with humans.
The interaction of the coronavirus spike protein with its complement host cell receptor
is central in determining the tissue tropism, Infectivity, and species range of the virus.
Antibiotics should only be started within three weeks of onset of symptoms, given their lack of
effect on the course of the illness, and the period of Infectivity.
