Doctor demonstration mask wearing.
Red Net Time November 2 (Correspondent Chen Siyu and Yang Zhengqiang) Vaccination is the most effective measure to prevent diseases. After being vaccinated, it can not only reduce the chance of being infected, but also if you are accidentally infected, the incidence, severe illness and mortality rate will be greatly reduced.
However, recently, many places in China have issued epidemic reports, and new cases have appeared in many provinces, which once again sounded the "warning bell" for epidemic prevention.
In this regard, on November 1, Huang Xi, director of the Department of Infection of Hunan Chest Hospital, reminded that after injection of the new crown vaccine, immunity can be produced and the risk of infection can be reduced, but the vaccine's protective effect is not 100%. Therefore, even if you are vaccinated, you should not take it lightly. You must insist on wearing masks, washing hands frequently, ventilating frequently, and maintaining social distance.
should protect yourself, wear masks,
In the face of this round of COVID-19, Huang Xi said that wearing masks is an effective way to reduce public cross-infection, effectively reduce the risk of transmission, prevent the spread of the epidemic, and ensure the health of the people.
study shows that when both carriers of the new coronavirus have come into close contact with healthy people, the infection rate is 90% when neither of them wear masks; when healthy people wear masks, the infectious rate is 30%; when carriers of the new coronavirus have a contagious rate is 5% when they wear masks; when both of them wear masks, the contagious rate is reduced to 1.5%.
When wearing a mask, the mask should cover the mouth and nose, and adjust the nose clip (the wire on the upper edge of the mask) to fit the face. During the wearing process, avoid touching the inside and outside of the mask with your hands; when taking off the mask, you can only touch the straps at both ends of the mask. Huang Xi said that wearing multiple masks is easier to make the masks damp and reduce the protective effect.
"Under normal circumstances, when we wear masks, our neck and jaw are exposed. If the mask is pulled down, it will be contaminated by bacteria and viruses in the neck or jaw." Huang Xi introduced that wearing a mask correctly can effectively block the spread of bacteria and viruses, but if wearing the mask wrongly, it will increase the risk of infection.
In addition, Huang Xi introduced that disposable medical masks and medical surgical masks are both disposable, and the use time should not exceed 4 hours. During the trip, it is recommended to keep one or two more masks with you for emergencies. The use time of medical protective masks should be followed by the mask instructions.
Pay attention to hygiene, learn to wash your hands frequently
Washing hands frequently is one of the most convenient and effective ways to prevent such infectious diseases. It is even called the most economical "vaccine". Maintaining hand hygiene on the basis of wearing a mask is an important link that cannot be ignored.
Respiratory infectious diseases such as new coronary pneumonia are also transmitted through manual contact. In life, if a patient infected with viruses and bacteria contaminates door handles, bus railings, elevator buttons and other objects by sneezing, coughing, etc., then others will easily touch these objects accidentally, resulting in contamination of their hands. At this time, if you touch your nose, mouth, and eyes with dirty hands, the virus will easily be "sent" to the human body, inducing viral infection and endangering health.
"Washing hands can prevent 80% of the diseases, reduce diarrhea and 1/4 of the respiratory infection, and have a preventive effect on blood system diseases, digestive tract diseases, skin diseases, eye infections, etc.." Huang Xi reminded that in addition to wearing masks scientifically, we must also wash hands in the correct way to maintain hand hygiene to reduce the spread of viruses and bacteria.
Air circulates, usually open windows for ventilation
In the current epidemic situation, the concept of "wearing a mask and washing hands frequently" has been deeply rooted in people's hearts, but there is one thing that is as important as them, but many people ignore it, that is, open windows for ventilation.
Open windows to ventilation help reduce the amount of viruses that may exist in the room and also helps the exchange of indoor and outdoor air. The outdoor air is "diluted" and it is almost impossible to bring the virus into the room.
Open windows to ensure the number of ventilation times, and ventilate at least 3 times a day. Ventilation in workplaces that may be contaminated requires about 5 minutes. Air should be kept in circulation.
At the same time, pay attention to the ventilation time. When opening the windows without wind or breeze, it is recommended to open the windows for 20-30 minutes. If you only open a small gap, the opening windows for 30-60 minutes.
refuses to gather together, keep a safe distance
Respiratory infectious diseases such as the new crown can be transmitted through close-range droplets. When you speak, cough or sneeze, the virus will be excreted into the air with droplets.
study shows that under the action of gravity, the horizontal distance between droplets from the mouth and nose of the human body and landing is generally within 1 meter. If close contact is made, there is a risk of infection if droplets containing virus are inhaled.
Huang Xi suggests that the public should sit in different seats during travel and dinner. When talking and communicating with people in public, keep at least 1 meter away from each other and refuse to gather together.
In addition, good hygiene habits should be developed and cough etiquette should be followed to reduce the spread of viruses and bacteria. At the same time, people with a higher risk of infection such as the elderly, children and patients with chronic diseases should pay more attention to protection. We must avoid crowded places, strengthen outdoor physical exercise, and improve our body's immunity. If you have symptoms such as fever and cough, you should go to the hospital for treatment in time.
