In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks (RR 0.78, 95% CI 0.51–1.20; I2 = 30%, p = 0.25) (Figure 2). One study evaluated the use of masks among pilgrims from Australia during the Hajj pilgrimage and reported no major difference in the risk for laboratory-confirmed influenza virus infection in the control or mask group (33). Two studies in university settings assessed the effectiveness of face masks for primary protection by monitoring the incidence of laboratory-confirmed influenza among student hall residents for 5 months (9,10). The overall reduction in ILI or laboratory-confirmed influenza cases in the face mask group was not significant in either studies (9,10). Study designs in the 7 household studies were slightly different: 1 study provided face masks and P2 respirators for household contacts only (34), another study evaluated face mask use as a source control for infected persons only (35), and the remaining studies provided masks for the infected persons as well as their close contacts (11–13,15,17). None of the household studies reported a significant reduction in secondary laboratory-confirmed influenza virus infections in the face mask group (11–13,15,17,34,35). Most studies were underpowered because of limited sample size, and some studies also reported suboptimal adherence in the face mask group.Disposable medical masks (also known as surgical masks) are loose-fitting devices that were designed to be worn by medical personnel to protect accidental contamination of patient wounds, and to protect the wearer against splashes or sprays of bodily fluids (36). There is limited evidence for their effectiveness in preventing influenza virus transmission either when worn by the infected person for source control or when worn by uninfected persons to reduce exposure. Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza."[URL unfurl="true"]https://www.cdc.gov/flu/symptoms/flu-vs-covid19.htm[/URL]How it spreadsSimilarities"Both COVID-19 and flu can spread from person-to-person, between people who are in close contact with one another (within about 6 feet).Both are spread mainly by droplets made when people with the illness (COVID-19 or flu) cough, sneeze, or talk.These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.It may be possible that a person can get infected by physical human contact (e.g. shaking hands) or by touching a surface or object that has virus on it and then touching his or her own mouth, nose, or possibly their eyes.Both flu virus and SARS-CoV-2 may be spread to others by people before they begin showing symptoms, with very mild symptoms or who never developed symptoms (asymptomatic)."Masks have not proven to be effective at preventing the spread of the flu. The flu and covid spread in the same ways.Coclusion: masks are ineffective at stopping the spread of covid.</blockquote>
