5 Important Rules Against Coronavirus: The Covid-19 pandemic caused by the new type of corona virus has recently taken off in our country and in the world. In preventing the spread of the infection, it is vital to follow the cleaning rules as well as maintaining physical distance and paying attention to the use of masks. However, due to the overwhelming heat, serious problems are experienced in using masks and adapting to social distance. Professor of Ear Nose Throat Diseases Department. Dr. Robert Jones made suggestions to protect against coronavirus.
1- Do not be unmasked indoors!
The coronavirus spreads to the environment with droplet infection from sick individuals. The risk increases especially during coughing and sneezing. During the conversation, secretions may spread around as micro particles. Although the density of these microparticles decreases over time, they can remain suspended in the air for a considerable time. When the infected air is inhaled by healthy individuals, it is easier for the virus to reach people through the nose and mouth. This risk is much higher especially indoors. While the particles that spread to the air in an open area can be dispersed rapidly with the help of small breezes, they can remain suspended in the air for hours indoors. For this reason, the importance of the mask emerges more in closed environments.
2- Physical distance is a must
In closed environments, when sick people sneeze and cough, the infection can spread 3-5 meters away. The longer the distance, the less the density of the virus in the air. In this respect, the importance of physical distance also emerges. Many people can pass the disease on to other people without any symptoms. Even more importantly, it has been shown that the virus was spread from sick people in the first days when symptoms did not appear yet. For this reason, it is not possible to be sure whether people are carrying the Covid-19 virus at that time.
3- The mask should cover your mouth and nose
The easier it is for the disease to be transmitted through an airborne droplet infection, the more practical it is to avoid it. The use of masks is very important, especially in order to prevent the secretions of sick people from spreading around. Regardless of the type of mask, it should be used duly, in a way that the mouth and nose are covered. In this way, a person wearing a mask; It can be largely protected from the secretions that spread as micro particles during sneezing, coughing and speaking of others. Practically, a mask may not be worn in an open-air environment where nobody is around. However, it is vitally important for everyone to wear a mask in closed environments, especially in crowded places where physical distance is difficult to control.
4- Test the air permeability in your mask
Some of the masks in the market are hand made, made of different fabrics, washable, reusable masks. The lower the air permeability in the mask, the higher its protection. If the flame of a candle or lighter held in front of the mask is extinguished when blown while the mask is on, it generally has little protection. In other words, the amount of air that can pass through a good mask should be significantly reduced. The mask worn is to control the spread of micro secretions in the patient who is possibly sick. In other words, the person wearing a mask will also protect the people around him.
5- Special masks should be used for patients and their relatives
There are also varieties of masks. Three-layer surgical masks are frequently used, and the masks that professional teams should wear also differ. There are also special-purpose masks that should be used by healthcare professionals and patient relatives who are interested in the treatment of people who are very likely to be sick in health institutions or individuals diagnosed with Covid-19. The protection rates of these types of masks vary according to the filter permeability. These types of masks, generally called N95, are grouped as FFP1 masks that provide 80-90% protection for coronavirus, FFP2 masks that provide 90-95% protection, and FFP3 masks that provide 97-99% protection.
