Can regular nasal rinsing with a saline solution or using mouthwash help prevent coronavirus infection? Are hand dryers effective in killing coronavirus?
Are hand dryers effective in killing coronavirus?
No. Drying hands using hand dryers, which are often available in public restrooms, does not kill coronavirus. To protect against coronavirus, hands should be washed frequently with an alcohol-based hand sanitizer (the concentration should be at least 60%) or soapy water for at least 20 seconds.
Are ultraviolet disinfection lamps effective in killing coronavirus?
UV lamps should not be used to disinfect hands (or skin in general). They can cause damage to the skin.
Can spraying alcohol-based or chlorine-releasing disinfectants on the body kill coronavirus?
No. Spraying alcohol-based or chlorine-releasing disinfectants on the body will not kill coronavirus that has already entered the body. Spraying yourself with such products can be dangerous and harmful to your skin, mucous membranes (e.g., eyes, mouth) and respiratory tract, and clothing. Disinfectants containing alcohol or chlorine can be used to disinfect surfaces, but must be used properly.
Can regular nasal rinsing with a saline solution help prevent coronavirus infection?

Can using mouthwash protect against coronavirus infection?
No. There is no evidence that the use of mouthwash protects against coronavirus infection.
Some mouthwashes can eliminate specific microorganisms in saliva. However, this does not mean that their use protects against coronavirus infection.
