In addition to practicing good daily hygiene, wearing masks, washing hands frequently, and ventilation, how can you prevent COVID-19?

On May 9, the Chinese Journal of Eye, Ear, and Throat published online, ahead of schedule, theExpert consensus on nasal saline irrigation for prevention of Novel Coronavirus infection, which states that,As a common local nasal physiotherapy, nasal saline irrigation can reduce viral infection and speed up inflammatory recovery with low cost and side effects. It can be an economical and effective method for the prevention and treatment of Novel coronavirus infection.

This study was led by the China Association for Nasal Diseases Research, with the participation of young and middle-aged rhinologists from 27 well-known hospitals, including Eye, Ear, Nose and Throat Hospital affiliated to Fudan University, Tongji Hospital Affiliated to Tongji University, The Sixth People's Hospital affiliated to Shanghai Jiaotong University, West China Hospital of Sichuan University, and Beijing Tongren Hospital affiliated to Capital Medical University.

It is shown that human nasal epithelium is susceptible to novel coronavirus infection, and goblet cells and secretory cells express high levels of angiotensin converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2), which are key molecules of viral infection.

Nasal saline flushing can clean the dust particles, allergens and air pollutants in the nasal cavity, improve the mucociliary swing function, reduce mucosal edema, promote local blood circulation, and enhance mucosal cleaning function.

At the same time,Saline also helps to increase the hydration of mucous layer, improve cilia swing frequency and reduce the production of local inflammatory mediators.

Saline irrigation is especially useful for improving mucin-cilia dysfunction and mucus stasis caused by viral infection.

Flushing method:

1. Take the low position of one side of the head and alternate the nasal passages on both sides.

2, start from the side of the heavy nasal congestion, so as not to lead to increased hydraulic pressure in the nasopharynx, resulting in otitis media.

3. During the washing process, observe whether there is blood, scab and purulent secretions in the washing solution at any time.

4. Do not breathe in or talk when rinsing, so as not to cause aspiration, choking or middle ear infection.

5. Conventional irrigation treatment, usually twice a day, 5-10 min each time, with no limit on duration.
