вЂњIn the absence of robust contact tracing, masks and social distancing are our best defenses,вЂќ Prescott said. More generally, experts extol the benefits of face coverings as protection against the novel coronavirus. The caregiver may also wear a cloth face covering when looking after a person who is sick. A person who is sick should wear a cloth face covering when they are around other people at home and out, except for young children under the age of two and anyone who has trouble breathing. The CDC recommends the use of face masks at home only in specific circumstances. The general idea behind face masks is to break the chain of infection in the population,вЂќ Karn explained.Д¬aution is, however, advised when putting on and removing a face mask to avoid further contamination, as explained in a WHO graphic.ДЄ screenshot of a WHO graphic taken on June 17, 2020 вЂњIf you are alone in a car there is no reason to wear a mask, but it should be put on when leaving the car if other people are being encountered. Claim: Pull off your mask when you are alone If people can transplant an organ or perform brain surgery while wearing a mask, it is reasonable to ask people to wear them in public to reduce transmission of novel coronavirus,вЂќ Ryan Marino, an emergency medicine physician at University Hospitals Cleveland Medical Center, told AFP via a direct message on Twitter.ДЄFP Canada debunked a video of a nurse warning against continuously wearing face masks, claiming they can harm the body. вЂњNobody has ever died as a direct result of wearing a surgical mask. Claim: Wearing a mask for an extended time may lead to death Jonathan Karn, virologist and director of the Cleveland COVID Task Force, told AFP by email that peopleВ should not вЂњstart feeling weak or dieвЂќ while wearing вЂњa light surgical mask or homemade cloth mask.вЂќДЄn AFP graphic illustrating the simplest way to make your own mask with just a piece of fabric, like a tea towel, and two rubber bandsД¬laims that the use of masks worsens the immune system are also false, AFP USA found in another fact-check. вЂњIt is hard to refute someoneвЂ™s subjective feelings,вЂќ Prescott said, but вЂњobjective data suggests that surgical and fabric face masks are safe for the vast majority of the population who donвЂ™t have severe underlying lung disease.вЂќ Claim: If you wear a surgical mask for a long time, you will start feeling weak Prolonged use of a well-made mask is unlikely to cause hypercapnia, a build-up of carbon dioxide in the blood, AFP found in another fact-check. вЂњNot only is there absolutely no credible evidence to the contrary, but many professions wear masks for long periods of time on a regular basis with no adverse effects, including surgeons, lab technicians, and painters,вЂќ he told AFP in a directВ message on Twitter. Josh Mugele, Emergency Department Physician at Northeast Georgia Medical Center in Gainesville, Georgia, says there are вЂњzero adverse effects to long-term mask usage.вЂќ If the person wearing a mask is experiencing headaches, вЂњthey can result from a variety of things вЂ“ such as uncomfortable ear loops on masks вЂ“ so I would not assume that headaches are a reflection of low oxygen,вЂќ Prescott added. вЂњMy interpretation is that-for 99.9 percent of the population without severe underlying lung disease-there are at most only trivial decreases in blood oxygen levels with surgical or cloth masks,вЂќ she said. The report found a 'decreaseвЂќ in oxygen saturation in surgeons, вЂњeither due to the facial mask or the operational stress.вЂќ Prescott, who is also a staff physician at the Veterans AffairsВ Ann Arbor Health Care System, referred to a report published in 2008В which studied deoxygenation induced by surgical masks during major surgeries. The CDC does not recommend the use of N-95 masks to the general public. вЂњIt is true that masks may cause trivial changes to oxygen and carbon dioxide levels, but this is mainly seen with N95, not surgical or cloth face masks,вЂќ Hallie Prescott, Assistant Professor inВ the Division of Pulmonary & Critical Care Medicine at the University of Michigan Health System, said to AFP by email.
