Wearing a mask, washing hands frequently or maintaining social distancing can all help slow the spread of the virus. Wearing a mask can reduce the risk of contracting airborne infectious diseases. Moreover, because the cost of masks is lower, this method can spread to more people. Although masks are a very simple tool, we must also learn to distinguish the types and functions of masks and the precautions for using masks to avoid stepping on minefields.
As the new crown pneumonia epidemic spreads globally, wearing a mask or face mask has become more and more important than ever. Although many Asian countries have been adopting this practice for a long time, current scientific research shows that wearing masks can effectively inhibit the spread of the virus, thereby making the situation of wearing masks more common. In some areas of the world that did not wear masks before It was also mandatory to wear a mask. Here is what you need to know about masks and why you should wear them. How masks prevent the spread of new coronary pneumonia and other viruses Many people misunderstand masks that they can prevent themselves from getting sick. Most masks will not prevent you from being infected by viruses that spread through the air, but they are meant to prevent you from infecting other people. Wearing a mask correctly and maintaining good hand hygiene and social distance are the best ways to help you and others around you stay healthy. When we speak, breathe, sneeze or cough, the role of masks is to prevent the spread of saliva and respiratory droplets containing bacteria and viruses. Since the outbreak of the new crown pneumonia, many studies have confirmed that wearing a mask is one of the most effective ways to help prevent the spread of the virus. There are mainly three types of masks for different types of masks. The price and practicality of each mask are different. It is recommended to wear surgical masks or fabric masks in public. N95 protective masks: These masks are more expensive than surgical masks and are often supplied in lesser quantities, but due to their suitability and design, they are generally more effective than other types of masks. Therefore, these masks should be reserved for medical professionals. N95 protective masks became more well-known during the SARS outbreak in 2003. N95 protective mask is a close-fitting disposable mask that can filter out at least 95% of droplets and aerosols. Surgical/Medical Masks: These disposable masks were originally made for doctors, dentists, and surgeons to prevent the spread of bacteria and viruses from doctors to patients. They are non-adherent and usually have three or more layers. Although they can effectively filter out larger particles in the air, they are looser, so it is easier for air and pollutants to flow out of their edges. Fabric masks: These masks are usually hand-made from a variety of materials, and their shape, fit, and performance may vary. These masks are attractive because they can be made of more organic materials and can be reused. Some fabric masks can even be equipped with an additional filter. Studies have shown that fabric masks, especially masks made of multiple layers of cotton, are almost as effective as surgical masks in slowing the spread of the virus. Now, the CDC also recommends that ordinary people wear fabric masks. In one study, the filtration rate of different fabric materials and thicknesses was between 49% and 86%. Why wear masks Now, the CDC and the World Health Organization (WHO) recommend that the public wear masks in public. Although this is not always recommended, science has begun to prove that masks are related to reducing the spread of the new crown virus and other diseases, which has led more governments and companies to adopt mask injunctions. This is especially important during the COVID-19 pandemic, because asymptomatic carriers of the virus are very common, which means you may be infected with the virus without any visible signs or symptoms. In many Asian regions (such as Hong Kong), wearing masks in public has almost become a common phenomenon. Considering population density, minimum lockdown or social distancing measures, the spread of the virus has been low. In the United States, the transmission rate has always been high, and people wearing masks are generally very low. A study was conducted in 15 states, including the District of Columbia, to study the virus after being forced to wear masks. Studies have shown that the spread of the virus has slowed down significantly after the mask injunction was implemented. In an experiment using high-speed video, it demonstrated that even when a person is just talking, hundreds of droplets of 20 to 500 microns will be produced, but when a simple fabric covers the mouth, almost all of the droplets are Blocked. In addition, another study showed that when unwell people wear masks, the spread of flu or cold viruses will be greatly reduced. As the COVID-19 virus is highly contagious, it is more necessary than ever to take these recommendations on masks seriously to ensure the safety of your friends, family members, especially those with weakened immune systems and at-risk individuals. By wearing a mask, you can prevent others or their loved ones from contracting the COVID-19 virus. Hygiene tips for wearing a mask and keeping healthy, wash your hands often with soap for 20-30 seconds. If you cannot wash your hands, please use hand sanitizer (alcohol content at least 70%) after touching any public place. Try to avoid going to public places or any social gatherings. If you must go to public places, always wear a mask, avoid crowds and maintain social distance (minimum 1.5 meters). Wash and/or disinfect hands before and after putting on or taking off the mask. Make sure the mask covers your mouth and nose. Do not wear under the nose or chin. Make sure to put the mask tightly behind the ear. Do not touch when wearing a mask. Disposable masks should usually only be worn once. Wearing them multiple times increases the risk of spreading bacteria. If you want to remove the mask to eat or drink, place the mask in a bag or suitable container to avoid contaminating other surface areas. Wear a mask immediately after eating/drinking. If you touch the mask accidentally, wash or disinfect your hands. Fabric masks should be washed regularly with soap and water. Fabric masks can be washed by hand or with other clothing. For fabric masks, once soiled, they should be placed in a sealed bag until they can be washed. After removing the mask, be sure to wash your hands. For disposable masks, make sure to dispose of them correctly. Masks cannot replace social distancing or good hand hygiene. Don't let people who have difficulty breathing wear a mask. Don't let children under two years old wear masks. For children who are not used to wearing masks, let them get used to wearing masks intermittently at home. This will help children get used to wearing a mask in public or when it is mandatory to wear a mask when returning to school. Combined with good hand hygiene and social distancing, wearing a mask is a cheap, simple, sustainable and effective way to help control the spread of the COVID-19 virus.
