1. “So far, most studies found little to no evidence for the effectiveness of cloth face masks in the general population, neither as personal protective equipment nor as a source control.” Are Face Masks Effective? The Evidence
  2. “Wearing a used mask could be more dangerous than not wearing one at all when it comes to warding off COVID-19, a new study has found.” Wearing a used mask could be worse than no mask amid COVID-19: study
  3. A total of 343 healthcare professionals on the COVID-19 front lines participated in this study. The majority were female (n = 315) and 227 were located in New York City. 225 respondents identified as White, 34 as Hispanic, 23 as African American, and 61 as “other” ethnicity. 314 respondents reported adverse effects from prolonged mask use with headaches being the most common complaint (n = 245). Skin breakdown was experienced by 175 respondents, and acne was reported in 182 respondents. Impaired cognition was reported in 81 respondents. Previous history of headaches (n = 98), skin sensitivity (n = 164), and acne (n = 121) were found in some respondents. Some respondents experienced resolved side effects once masks were removed, while others required physical or medical intervention. Adverse Effects of Prolonged Mask Use among Healthcare Professionals during COVID-19
  4. The two potential side effects that have already been acknowledged are: (1) Wearing a face mask may give a false sense of security and make people adopt a reduction in compliance with other infection control measures, including social distancing and hands washing.[3](2) Inappropriate use of face mask: people must not touch their masks, must change their single-use masks frequently or wash them regularly, dispose them correctly and adopt other management measures, otherwise their risks and those of others may increase.[3,4] Face masks for the public during the covid-19 crisis
  5. “Many people have reported some unpleasant side effects of mask wearing, such as anxiety, headaches, confusion and fatigue. This can be especially challenging for those who have to wear masks throughout their workday, as well as those with preexisting respiratory problems. Shallow breathing combined with mask wearing can result in people experiencing anxiety, shortness of breath, headaches, dizziness, confusion, numbness or tingling in hands and feet, and sleep problems.” Combating the effects of mask wearing
  6. “Studies of the COVID-19 vaccines only measured whether vaccinated people developed symptoms, not whether they got infected. We know that you can become infected with the coronavirus and be asymptomatic, meaning you never develop symptoms. Asymptomatic people can still spread COVID-19 to others.” Yes, you still need to wear a mask after you get the COVID-19 vaccine. Here’s why.
  7. “The evidence is not sufficiently strong to support widespread use of face masks as a protective measure against covid-19. However, there is enough evidence to support the use of face masks for short periods of time by particularly vulnerable individuals when in transient higher risk situations.” Covid-19: What is the evidence for cloth masks?
