Recently, there are rumors in the society that "the medical mask has little protective effect on Omircong's mutation strains". Is there a scientific basis for this rumor? On September 2nd, the reporter asked Yang Hongcai, the chief physician of the Popular Diseases of the Disease Prevention and Control Center of the Autonomous Region and Yang Hongcai, the director of the Disease Control and Infection Control Center of the Original Autonomous Region.

"Regardless of how Omikon mutated, it is essentially the new crown virus, the biological nature and communication methods have not changed. The transmission approach is still droplets, close contact and gas solution." Yang Hongcai said, medical masks, medical surgery masks, N95, N95 The masks are air particles filters, and they can achieve the purpose of dust removal, sterilization (virus) after wearing.

To make the mask play the maximum filtering effect, when wearing, the confinement of the mask and the face is essential.

Under normal circumstances, the public's use of medical masks or disposable surgical masks can play a protective role.

Although the particulate protective mask (N95/KN95) has better protection, it has poor breathability, has a large breathing resistance, and is not suitable for long -term wear. In non -high -risk environment or without special trainers, it is not recommended to wear.

When wearing a medical protective mask and particulate protective masks, a closed test must be performed. If there is a gap between the mask and the face, when breathing, the dust, droplets, and gas solidar of the virus can be accompanied by the air flow, and enter our body through the gap to increase the risk of infection.

Today, according to everyone's preferences, many online stores have launched more personalized masks. Yang Hongcai suggested that when you buy, you will recognize the execution standards during the production of masks.

At present, the masks incorporated into the national standard range are: daily protective masks (GB/T32610-2016), particulate matter protective masks (GB2626-2006), one-time use of medical masks (YY/T0969-2013), medical surgery mask (YY0469-- 2011), medical protective mask (GB19083-2010) and so on.

Medical masks are mainly divided into three categories, using medical masks, medical surgical masks, and medical protective masks at one time. Drug supervision departments in various countries use medical masks as medical equipment for supervision and management to ensure the safety and effectiveness of the product.

"The N95/KN95 mask is not a medical mask. It is a particle protective mask. The protection effect of non -oily particulate matter reaches more than 95%, but it cannot effectively protect blood splash." Yang Hongcai said.
