.Sh DESCRIPTION
The
.Nm
family of diseases, attached to humanity via a spike protein bus in
the year 2019 as
.Nm covid19 ,
is a contagious respiratory and neurological disease caused by the
coronavirus SARS-CoV-2.
.Pp
.Nm
is spread human-to-human mainly through small droplets and aerosols,
especially in crowds, closed spaces, and close contact.
Some approaches to mitigate transmission:
.Bl -bullet
.It
Good ventilation with fresh air, and high-efficiency particulate air
filtration (HEPA), can mitigate accumulation of aerosols in indoor
settings, for activities that can't be moved outdoors.
.It
Widespread use of paper or cloth facial masks covering mouth and nose
is an effective population-wide mitigation reducing dispersal of
droplets and aerosols from carriers, many of whom are asymptomatic or
presymptomatic.
.It
Wearing European FFP2 masks, American N95 masks, or Chinese KN95 masks,
if appropriately fitted to the face, reduces individual risk of
contracting
.Nm .
(However, a mask with an output vent to facilitate exhaling should be
worn only with another paper or cloth mask over it, to avoid spreading
exhaled virus particles if the wearer is a carrier.)
.El
.Pp
Several vaccines have been developed, tested in large-scale randomized
clinical trials, and approved by regulatory bodies to immunize
populations against SARS-CoV-2:
.Bl -bullet -compact
.It
Moderna (United States)
.It
Pfizer-BioNTech (multinational)
.It
Sputnik V (Russia)
.It
Oxford-AstraZeneca (multinational)
.It
Novavax (United Kingdom and South Africa)
.It
BBIBP-CorV (multinational)
.It
CoronaVac (Brazil)
.It
Johnson & Johnson, a.k.a. Janssen (multinational)
.It
Covaxin (India)
.It
Convidecia (multinational)
.El
.Pp
The approved
.Nm
vaccines are some of the safest and most efficacious vaccines in
history, with almost all of them preventing essentially 100% of severe
cases of the disease and hospitalization, and preventing the vast
majority of mild cases, according to randomized clinical trials.

The
