Wearing masks and social distancing Actually COVID-19 job content, according to a new study

The proven method to control an infectious disease such COVID-19 are not easy to follow-keeping six feet from others, wearing face masks in public, and if you’re a health care worker, carrying shields to protect, so your eyes. But in a study published Monday in The Lancet, the researchers put even the strongest evidence that these practices can reduce effectively the risk of spreading the virus. An international team of scientists led by senior author Dr. Holger Schünemann, professor of clinical epidemiology and medicine at McMaster University in Ontario, Canada, reviewed 172 studies conducted in 16 countries that examined the connection between the social distancing, wearing masks, and wear eye protection, and the risk of transmitting the virus. The studies included people with COVID-19 infections in addition to two caused them coronavirus, SARS and MERS disease. The study was observational, meaning that follows infection rates among men who practice any of the above behaviors. Of the 172 studies, 44 (with more than 25,000 participants) between these comparisons that have followed the behavior and those who do not. When it comes to social distancing, the analysis showed that on average the risk, infected, when the remaining 1 meter (slightly more than 3 ft) from an infected person was about 3%, during a stay of less than one meter l ‘ from each other eliminates the risk increased to 13%. More people are distant, the lower the risk. In fact, the risk is halved for each additional meter distances up to 3 meters (about 10 feet). “What I was trying to do everything possible to bring together and clarify what could be by far the most effective, rather than an arbitrary threshold,” says Schünemann. away respiratory droplets from coughs or sneezes basis of this trip in general, the more the public health policy currently recommends at least 2 meters (about 6.7 feet) apart in public areas are available that support the study results. “The virus does not know what a meter is or what six feet,” says Schünemann. “This suggests that two meters or 6.7 meters, it looks like there could be more than a meter or three feet more protection.” The data also supports the benefits of eye protection for health care workers. The risk of infection in people who wore glasses, goggles or other face was 6% compared to 16% do not wear such protection. The studies included health workers in hospitals, as well as people living in households with an infected person. The researchers monitored if those who are in close contact with people who have an infection from Corona had kept his distance, wearing a protective mask and eye contact, and even if it is infected. “I was surprised by the size of the effect,” says Schünemann. “In epidemiology, we often see small effects, and large or very large considering all the effects that you can see here.” It is said that the advice actual results to public health to bear the risk of spreading COVID-19 to reduce, but adds that need further study. For example, it is not yet clear whether a distance meter may be sufficient in some environments (compared to 2 meters that are currently recommended). In addition, greater distances may be required when people in dense environments or surrounding area and is still uncertain what the ideal distance in these scenarios would be collected. In the health sector such as hospitals, you are needed similar studies to tease apart what types of face masks are best for different situations. The study found that the quality medical and surgical use N95 masks paper masks in the medical field, offered to provide the best protection, but the cloth homemade masks are still in effect for the general public. This data, says Shunemann support helps reduce the virus a mask both the risk of spread, if you are infected, and the possibility of lowering become infected if you have not yet contracted the virus. “The type of masks are to be worn, and the wearer of the mask should be further studied in randomized controlled trials,” says Schünemann. “But having said that, my interpretation is that wearing a homemade mask is best to wear nothing.”
