Partner evidence products

Evidence products prepared or updated by our partners and in collaboration with a network of evidence-support units supported by a secretariat housed at the McMaster health Forum can be accessed below.

Note that this page includes a suite of living evidence syntheses (LES) that synthesize the best-available evidence about the effectiveness of six public health and social measures (quarantine and isolation, masks, ventilation, physical distancing, reduction of contacts, hand hygiene and respiratory etiquette, cleaning, and disinfecting), as well as combinations of and adherence to these measures, in preventing transmission of respiratory infectious diseases.
