Nasopharyngeal wash in preventing and treating upper respiratory tract infections: Could it prevent COVID-19?

In pathogenesis of COVID-19, hands play an important role by transporting virus from fomites mainly to nose and mouth. From mouth and nose virus spreads in the body. Saline wash of the nasal passage, mouth, and throat would probably eliminate or reduce viral load in the body mechanically at least in the initial stage of the pathogenesis. This could be similar to hand washing to contain the spread of the infection. Therefore, hypertonic saline gargles and nasal wash may work in preventing the disease and may also be useful in reducing nasopharyngeal viral load to provide symptomatic relief. Further, it may reduce viral shedding and reduce the transmission of the illness. This may break the chain of infection. COVID 19 disease is mild in eighty percent of patients and resolves spontaneously. Therefore, nasopharyngeal wash may be useful especially in subgroup of the population at high risk such as subjects with comorbid conditions and above 60 years of age. In this rapid systematic review to evaluate effect of nasopharyngeal wash majority of studies had methodological limitations. However, few studies using hypertonic saline gargles and nasal wash showed to prevent symptoms and reduce transmission, symptoms, need for symptomatic medication, and viral loads in patients of the common cold. Its utility, however, has to be studied for SARS-CoV-2 which has significant mutations from the coronaviruses that causes the common cold. Since it has been shown to work for a multitude of common viruses, logically, it should work for SARS-CoV-2 as well. The therapy could be studied as an easily available, and affordable add on modality to curb the transmission of the SARS-CoV-2. As we await definitive therapy to fight the pandemic this relative safe technique may give a ray of hope especially in prevention. COVID 19 infection starts in nasopharynx but involves lungs and other organs of the body. Therefore the effect of nasopharyngeal wash may have a limited action at nasopharynx; however, it may be more useful in prevention. The potential disadvantages of the nasal wash therapy are the discomfort in performing the procedure, however, in previous studies, it has been shown to be accepted in around 87% individuals. The second disadvantage would be the possible transmission of viral infection through the equipment used for the wash and the area where the procedure is performed. This limitation could be addressed easily by maintaining strict measures with each person use one's own equipment with no sharing amongst each other. Further, the washbasin/sink where the procedure is performed can be cleaned postprocedure. Certain precautions should be followed prior to the procedure including the use of clean water which can be ensured by boiling and subsequently cooling it. The technique of learning of nasopharyngeal wash should be supervised initially. To read more-;year=2020;volume=37;issue=3;spage=246;epage=251;aulast=Singh



JalNedhi is good yogic kriya to be done under experts yes it does help in chr sinositis Allergic rhinitis Recurrent urti or pharyngitis But so far covid19 is concerned nothing can be said as this virus virulent and notorious it lodges down the respiratory tract and not in pharynx

Nicely explained but not practical in india because 40 % population has no home or water for residence and drinking. More than 50 % population still share common toilets and no body is there to clean properly and throughly the common place used for gargles . COVID 19 is a more serious and virulent virus changes mode of transmission regularly. Saline gargles and nasal washing is a very old therapy practice regularly by our fore father's. Good and thinkable points raised by you under circumstances not responding to any particular treatment or other options are under evaluation.

Thanks Dr Vipin Bihari Jain

COVID-19 infection starts in nasopharynx but involves lungs and other organs of the body. Therefore the effect of nasopharangeal wash may have a limited action at nasopharynx, however it may be more useful in prevention

Good but difficult i was not able to do it proper instrument & guru important any things save or minimize disease is welcome try yogic ashana

Just another hypothesis

It is only preventive measure


Who should be practicing this therapy ,l mean which persons, symptomatic/ asymptomatic,& how' he should dispose off this material ,it will spread the infection rather than control it

Worth trial any procedure helps in any way to reduce corona virus

Nice picture

Jala Naiti is helpful in many Respiratory Disorders and it's an integral part of Respiratory Hygiene as per the Ayurveda
