Can disposable medical masks be sprayed with medical alcohol for disinfection and reused? Feng Luzhao, a researcher at the Chinese Center for Disease Control and Prevention, introduced that ordinary residents use disposable masks in places where the risk is relatively low, which can be reused under the condition that the masks are clean and structurally complete, especially the inner layer is not contaminated. After each use they should be placed in a clean, dry and ventilated place.
Wearing a mask will increase the resistance to airflow, making it difficult for people to inhale the amount of air needed at the highest exercise level.
Epidemiology expert Zeng Guang said in an exclusive interview with CCTV reporters that wearing a medical mask is to contribute to epidemic prevention and control. Everyone must wear a medical mask when they go out, which is responsible for themselves and society. Everyone wears a medical mask, the rate of disease transmission will decrease, which is conducive to contain the epidemic.
The main route of transmission of the new coronavirus is the spread of respiratory droplets. In protective equipment, the role of masks is irreplaceable. It can be said that the correctness of wearing a mask is directly related to the success or failure of protection. However, there are certain requirements for wearing masks, especially N95 protective masks. It does not mean that with N95 masks, everything is fine. Incorrect wearing is equivalent to invalid protection.
While N95 masks were purchased and used in large quantities, how to deal with them after use became a new problem in controlling the spread of pneumonia.
Whether the mask can be used again after cleaning can not be generalized, mainly related to factors such as the type of mask.
