COVID-19 is a new disease with no treatment and no vaccine so far. The pandemic is still growing in many areas. Among the core measures to prevent disease spread is the use of face masks. We observed 12,588 people in five Brazilian cities within the Baixada Santista metropolitan area. Even though this is densely populated region and heavily impacted by COVID-19 with a high risk population, only 45.1% of the observed population wore in face masks in a correct way, and another 15.5% simply did not use masks at all. The remainder used masks incorrectly, which is evidence of the worst scenario of people believing that they are protected when they are not. This is among the first studies, to the best of our knowledge, that measures real life compliance with face masks during this COVID-19 pandemic. It is our conclusion that it is paramount to first control the virus before allowing people back in the streets. We should not assume that people will wear masks properly. Equally important is to instruct and sensitize people on how to use face masks and why it is important.
