"no significant reduction in influenza transmission with the use of face masks"

"no major difference in the risk for laboratory-confirmed influenza virus infection in the control or mask group"

"The overall reduction in ILI or laboratory-confirmed influenza cases in the face mask group was not significant in either studies"

"None of the household studies reported a significant reduction in secondary laboratory-confirmed influenza virus infections in the face mask group"

"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."
