@Gezeurig Ik ga echt gillen. Het onderzoek waar Duitsland haar mondkapjesbeleid op baseert is dus gedaan door arts-epidemioloog Marianne van der Sande in 2008 TOEN ZE BIJ HET RIVM werkte. Dat zelfde RIVM erkent nu niet haar eigen onderzoek in 2008???

AI synopsis
What people are saying
Many posts reference earlier studies, particularly a notable 2008 article discussing mask efficacy, using phrases like 'All types of masks reduced aerosol exposure' to emphasize their importance. The choice of words—like 'strongly supportive' and 'evidence'—along with a tone of urgency in some posts, showcases a desire to reinforce the discussion around mask use, suggesting a societal need to revisit and value established research.
The majority of discussions reflect support for the publication's findings regarding masks, though some skepticism exists.
Participants demonstrate high curiosity about the effectiveness of masks, leading to various references to past studies.
While many posts refer to the research, they largely express opinions rather than deeply explore its implications.
Many contributors believe that the research findings could significantly influence public health policy and mask usage.
Abstract in brief
- Professional and home-made face masks can effectively reduce exposure to respiratory infections, which is important for managing potential influenza pandemics.
- Research showed that different types of masks—personal respirators, surgical masks, and homemade masks—offer varying levels of protection when worn by healthy individuals and simulated patients.
- While all masks decreased aerosol exposure, personal respirators provided the highest level of protection, and children were found to be less protected, highlighting the need for effective mask usage strategies.

@Kristen61112998 @adamTHX1138 @Hammbear While kids' masking is less effecient, probaly bc they wear poorer quality masks less well, it still makes a difference.
