Facial Masking for Covid-19 — Potential for “Variolation” as We Await a Vaccine (NEJM, 14th September)

https://www.nejm.org/doi/full/10.1056...

https://www.nejm.org/doi/pdf/10.1056/...

Universal mask wearing might make mild or asymptomatic disease more likely

A form of “variolation”

Inoculation

Generate immunity and thereby slow the spread of the virus

Viral shedding from the noses and mouths of patients, presymptomatic or asymptomatic

Shedding rates equivalent to those among symptomatic patients

SARS -1

A strong relationship between public masking and pandemic control

SARS - CoV - 2

Recent virologic, epidemiologic, and ecologic data

Hypothesis that facial masking may also reduce the severity of disease among people who
do become infected

Long-standing theory of viral pathogenesis

Severity of disease is proportionate to the viral inoculum received

Typical rate of asymptomatic infection, estimated to be 40% by the CDC in mid-July,

Settings with universal facial masking, 80%

Also less severe and less deaths

UK Recovery Trial

Neutralising antibodies

REGN-COV2 will be a new arm of the trial

Mixture of two monoclonal antibodies

US biotech company Regeneron

Regeneron, monoclonal antibodies, Ebola

Both attach to the spike of the virus at slightly different places
