Serious respiratory infectious diseases occur, the main points of home protection are as follows: 1. Keep indoor air circulation: regularly open the windows to ventilate, the outdoor air is fresh compared to the indoor air, and if dirty air is kept indoors for a long time, bacteria and viruses will accumulate in the house. In addition, if the house enters the infected or suspected infected persons, the virus will also gather in high concentration inside the house. If you can keep the windows open and ventilated, the fresh air from outside will dilute the virus and germs, and the chance of being infected will drop significantly; 2. Disinfection of objects and hands: regularly wipe the table with disinfectant and keep your hands clean. Studies have shown that respiratory infections are not only respiratory droplet infections, but hand contact is also a very important route. Patients can get the virus on the table or other objects by touching them, others can get the virus on their hands by touching them, and inadvertently rubbing their eyes or picking their nose with their hands can bring the germs into their bodies and possibly get infected. Therefore, it is very important to pay attention to hand hygiene; 3. Maintain regularity in living and eating: to keep the resistance at a sufficient and good level, which helps to resist the erosion of bacteria and external viruses. Content source: Dr. You Lai
