# 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.
