DESCRIPTION

     The covid family of diseases, attached to humanity via a spike protein
     bus in the year 2019 as covid19, is a contagious respiratory and
     neurological disease caused by the coronavirus SARS-CoV-2.

     covid is spread human-to-human mainly through small droplets and
     aerosols, especially in crowds, closed spaces, and close contact.  Some
     approaches to mitigate transmission:

     *   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.

     *   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.

     *   Wearing European FFP2 masks, American N95 masks, or Chinese KN95
         masks, if appropriately fitted to the face, reduces individual risk
         of contracting covid.  (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.)

     Several vaccines have been developed, tested in large-scale randomized
     clinical trials, and approved by regulatory bodies to immunize
     populations against SARS-CoV-2:
     *   Moderna (United States)
     *   Pfizer-BioNTech (multinational)
     *   Sputnik V (Russia)
     *   Oxford-AstraZeneca (multinational)
     *   Novavax (United Kingdom and South Africa)
     *   BBIBP-CorV (multinational)
     *   CoronaVac (Brazil)
     *   Johnson & Johnson, a.k.a. Janssen (multinational)
     *   Covaxin (India)
     *   Convidecia (multinational)

     The approved covid 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.

HISTORY

     2020 was a sordid year.


AUTHORS

     The covid man page was written by Taylor R Campbell
     <riastradh@NetBSD.org>, sourced from many thousands of hours of furiously
     doomscrolling epidemiology Twitter to pass the time during the pandemic.


CAVEATS

     The covid vaccines may cause muscle pain, redness, swelling, tiredness,
     headache, chills, fever, and/or nausea.  (Sure beats catching the plague,
     though!)


BUGS

     covid is technically caused by a virus, not a bug.
