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.
A May 2020 meta-study on pandemic influenza published by the US CDC found that face masks had no effect, neither as personal protective equipment nor as a source control. (Source)
A Danish randomized controlled trial with 6000 participants, published in the Annals of Internal Medicine in November 2020, found no statistically significant effect of high-quality medical face masks against SARS-CoV-2 infection in a community setting. (Source)
A large randomized controlled trial with close to 8000 participants, published in October 2020 in PLOS One , found that face masks “did not seem to be effective against laboratory-confirmed viral respiratory infections nor against clinical respiratory infection.” (Source)
A February 2021 review by the European CDC found no significant evidence supporting the effectiveness of non-medical and medical face masks in the community. Furthermore, the European CDC advised against the use of FFP2/N95 respirators by the general public. (Source)
A July 2020 review by the Oxford Centre for Evidence-Based Medicine found that there is no evidence for the effectiveness of cloth masks against virus infection or transmission. (Source)
A November 2020 Cochrane review found that face masks did not reduce influenza-like illness (ILI) cases, neither in the general population nor in health care workers. (Source)
An April 2020 review by two US professors in respiratory and infectious disease from the University of Illinois concluded that face masks have no effect in everyday life, neither as self-protection nor to protect third parties (so-called source control). (Source)
An article in the New England Journal of Medicine from May 2020 came to the conclusion that cloth face masks offer little to no protection in everyday life. (Source)
A 2015 study in the British Medical Journal BMJ Open found that cloth masks were penetrated by 97% of particles and may increase infection risk by retaining moisture or repeated use. (Source)
An August 2020 review by a German professor in virology, epidemiology and hygiene found that there is no evidence for the effectiveness of cloth face masks and that the improper daily use of masks by the public may in fact lead to an increase in infections.

For anybody interested, most of this guy’s posts, though they contain sources from pubmed, are plagiarized word-for-word from 3 facebook posts, a chiropractor, and a twitter thread. Links above. Hopefully we can just move this on to PWI.
The kid (my age at the time, anyways) was an econ student there, and didn’t like his brothers friends (me and a bunch of other guys/girls) making noise and partying when he was trying to study, so he booby trapped the bar by replacing the booze in one of the bottles with drain cleaner.
I took a behavioural econ and public policy class- most of the class was him pointing out how crap the US government is. We had two lectures on privacy and I thought he’d go on a rant about china- nope- he spent 5 min talking abt the cultural psychology of the chinese and went right back to dissing the US
I’d say manslaughter- murdered implies intent to kill
@SkyzykS idk if negligence covers it. From what I understand, negligence implies harm from inaction (ie it was his house and he left drano out in the counter next to the alcohol knowing that his friends were drunk and likely to mistake the drank for booze)
I would like to see people take “wearing the masks” to it’s most absurd conclusion such as wearing a Darth Vader mask. At least have some fun with this.
