How do you make a homemade cloth mask?

The CDC recommends using tightly woven cotton fabric, such as quilting fabric, cotton sheets, or T shirt fabric. It provided instructions on how to make masks with or without sewing, including using a bandana and coffee filter to create a face covering.1

But are they effective?

Very little good quality research exists on the use of cloth masks, especially in non-medical settings. One randomised controlled clinical trial of cloth masks, published in BMJ Open in 2015, compared their effectiveness with that of medical masks worn by hospital healthcare workers.2 The study, involving the industry partner 3M (which makes medical masks), reported that healthcare workers “should not use cloth masks as protection against respiratory infection. Cloth masks resulted in significantly higher rates of infection than medical masks, and also performed worse than the control arm.”

In an updated comment on the study (30 March),3 the authors said, “There have been a number of laboratory studies looking at the effectiveness of different types of cloth materials, single versus multiple layers and about the role that filters can play. However, none have been tested in a clinical trial for efficacy.”

A preprint of a rapid systematic review has assessed the current evidence on respiratory illnesses and the use of face masks (mainly surgical paper masks) in community settings.4 The paper, yet to be peer reviewed, included 31 studies, of which 12 were randomised controlled trials. The researchers reported that “wearing facemasks can be very slightly protective against primary infection from casual community contact, and modestly protective against household infections when both infected and uninfected members wear facemasks.” However, they said that many of the studies “suffered from poor compliance and controls.”

Ranking third on our Top-Grossing list is Steve Carell. Despicable Me 2 was a huge hit this year, bringing in $919 million at the box office. Overall, the franchise has earned $1.4 billion at the box office worldwide and a third movie, Minions, is on the way. Carell also appeared this year in the small indie The Way Way Back and The Incredible Burt Wonderstone. The latter failed to earn back its production budget at the box office but we’re only looking at ticket sales here — the film put another $22.5 million in Carell’s column for 2013.

That calm can sometimes be taken for a lack of the urgency that is vital in the fast-moving tech industry. Many were disappointed that Apple Watch was not made available to buy this year. But analysts say Apple’s approach of waiting until it has perfected a product usually leads to stronger long-term performance. Samsung, whose smartphone sales have suffered this year, is on its sixth-generation smartwatch, but has still not found a real hit.

What does WHO say?

In guidance issued on 6 April,5 WHO said that medical masks should be reserved for health workers. Most spread of the covid-19 virus is from known cases and requires contact with droplets from a cough or sneeze or infected surfaces. It said that “there is currently no evidence that wearing a mask (whether medical or other types) by healthy persons in the wider community setting, including universal community masking, can prevent them from infection with respiratory viruses, including covid-19.” Wearing masks in the community can also give people a false sense of security, it said, and lead to them neglecting other measures, such as hand hygiene and physical distancing.
