47 family of diseases, attached to humanity via a spike protein bus in
50 is a contagious respiratory and neurological disease caused by the
51 coronavirus SARS-CoV-2.
54 is spread human-to-human mainly through small droplets and aerosols,
55 especially in crowds, closed spaces, and close contact.
56 Some approaches to mitigate transmission:
59 Good ventilation with fresh air, and high-efficiency particulate air
60 filtration (HEPA), can mitigate accumulation of aerosols in indoor
61 settings, for activities that can't be moved outdoors.
63 Widespread use of paper or cloth facial masks covering mouth and nose
64 is an effective population-wide mitigation reducing dispersal of
65 droplets and aerosols from carriers, many of whom are asymptomatic or
68 Wearing European FFP2 masks, American N95 masks, or Chinese KN95 masks,
69 if appropriately fitted to the face, reduces individual risk of
72 (However, a mask with an output vent to facilitate exhaling should be
73 worn only with another paper or cloth mask over it, to avoid spreading
74 exhaled virus particles if the wearer is a carrier.)
77 Several vaccines have been developed, tested in large-scale randomized
78 clinical trials, and approved by regulatory bodies to immunize
79 populations against SARS-CoV-2:
82 Moderna (United States)
84 Pfizer-BioNTech (multinational)
88 Oxford-AstraZeneca (multinational)
90 Novavax (United Kingdom and South Africa)
92 BBIBP-CorV (multinational)
96 Johnson & Johnson, a.k.a. Janssen (multinational)
100 Convidecia (multinational)
105 vaccines are some of the safest and most efficacious vaccines in
106 history, with almost all of them preventing essentially 100% of severe
107 cases of the disease and hospitalization, and preventing the vast
108 majority of mild cases, according to randomized clinical trials.
