Who is that Masked Person: The Use of Face Masks on Mexico City Public Transportation During the Influenza a (H1N1) Outbreak
The use of face masks to prevent the spread of respiratory diseases in a public setting is controversial.

The Mexico City government made the use of face masks mandatory for bus and taxi drivers, but enforcement procedures differed for these two categories. Using an evidence-based approach, researchers collected data on the use of face masks over a two-week period. In the specific context of the Mexico City influenza outbreak, these data showed gender difference in compliance rates among metro passengers. Moreover, there was not a significant difference in compliance with mandatory and voluntary public health measures where the effect of the mandatory measures was diminished by insufficiently severe penalties, the lack of market forces to create compliance incentives and sufficient political influence to diminish enforcement. Voluntary compliance was diminished by lack of trust in the government
