Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Nasal Irrigation and gargling is a safe and commonly used mechanism to treat a variety of sinonasal diseases including sinusitis, rhinitis, and upper respiratory tract infections. Povidone-iodine(PVP-I) is a water-soluble complex of povidone, a carrier molecule, and iodine, which has powerful microbicidal activity. Also, recent evidence of in-vitro virucidal action of povidone-iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2) has been supported.
Therefore, the study is designed to assess the virucidal effect of nasal irrigation and gargling with PVP-I against SARS-CoV-2 located in the throat. The hypothesis was that the treatment would be effective in improving the negative conversion rate of SARS-CoV-2 nucleic acid on day 10.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study is a prospective, single-center, open-label, randomized controlled trial. The subjects who met the inclusion criteria were stratified according to gender, and randomly divided into control group and experimental group. Both groups were treated according to the diagnosis and treatment for novel coronavirus pneumonia (Trial Nine Edition). Of them, the control group is as blank control, and the experimental group was rinsed with PVP-I containing hypertonic lotion prepared by 0.9% Normal saline（NS）, 10% sodium chloride（NaCl）, and povidone-iodine（PVP-I） gargle four times a day.
The participants in the control group and the experimental group will be required to fill in a daily record and report the main complaint of discomfort. The subjects in the experimental group are also asked to record the implementation of oral and nasal flushing every day.
The researchers are going to record the test results of novel coronavirus nucleic acid samples from the nasopharynx of all subjects in the control group and the experimental group every day.
