There is uncertainty about the effects of face masks. The low to moderate certainty of evidence means our confidence in the effect estimate is limited, and that the true effect may be different from the observed estimate of the effect. The pooled results of RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks. There were no clear differences between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers when used in routine care to reduce respiratory viral infection. Hand hygiene is likely to modestly reduce the burden of respiratory illness, and although this effect was also present when ILI and laboratory‐confirmed influenza were analysed separately, it was not found to be a significant difference for the latter two outcomes. Harms associated with physical interventions were under‐investigated.
Mexican health officials are investigating after two babies died and 29 children were hospitalized from suspected adverse reactions to shots from the country’s national vaccination program.
Six of the children hospitalized in the southern Mexican state of Chiapas remain in serious condition, the Mexican Social Security Institute said on Sunday.
The illnesses were reported after 52 children from the rural mining community of La Pimienta were given vaccines Friday for tuberculosis, rotavirus and Hepatitis B, the institute said. Later that night, 31 of the children “presented adverse reactions presumably associated with the application of these vaccines,” officials said. Two of the children later died.
