What is a surgical mask?
Health workers to prevent the transfer of bacteria from their mouth to patients, usually wear a surgical mask, during surgery or when visiting vulnerable patients. The surgical mask can also protect against blood spraying from the patient during surgery. It is usually made of paper or synthetic materials suitable only for one -time use. This can provide a certain advantage and help reduce inhaled pollen, but should not be reused again. Because the sterile mask is not necessary when you try to avoid pollen, there are better face masks than a sterile surgical mask that prevents pollen from nose and mouth. Others use a surgical mask to protect against disease, but in fact it is not an advantage of the mask. It was possible to see that they wear surgical masks in public in the hope of giving them a little special protection against SARS. In fact, viral particles of diseases such as SARS can easily penetrate the surgical mask. In order to ensure actual protectionOn, you will need an airtight mask that can capture small viral particles, such as the masks of the National Institute for Safety and Health (NIOSH).
People with SARS or any disease can protect others from some exposure by wearing a surgical mask. Nevertheless, if a person infected with SARS coughs or sneezing, viruses penetrate mostly surgical masks. There is still a chance to transmit the virus when a person with a highly contagious disease wears a surgical mask. For this purpose, when some superflus are suspected, medical staff can wear masks with respirators and special safety suits so that the virus cannot be transmitted.
Surgic mask also has a somewhat limited time period in which it will be effective. They often work for a maximum of an hour or two. The moisture from the mouth and nose is eventually transferred to the outside of the mask, causing a simple surgical mask sterileonly for short periods of time. When parents or friends visit people with extremely vulnerable immune systems in front of diseases such as cancer, they must usually leave the room and change their masks after an hour or two hours.
Although wearing a surgical mask can briefly protect others from any germ that you could wear, the principle of avoiding the transmission of viruses is still through good hand washing practices. These should be observed in any public environment and are particularly important practice in hospitals.
