Hand washing guide: According to CDC guidelines, to avoid spreading 2019-nCoV or COVID, as well as all airborne pathogens, frequent hand washing is necessary. Generally washing hands with soap and water for at least 20 seconds is sufficient, but if this is not available using a alcohol based sanitizer with at least 60% alcohol content can work. Alcohol rapidly dries and evaporates so it's effect is short-lived.

No confirmed COVID-19 in my area, but stores are sold out of hand sanitizer and very low on disinfectant wipes. How concerned should we be at this point about contracting it while out in public? Is it safe to go about our regular daily activities?
Im a healthcare worker and had direct contact with a covid positive patient 5 days ago. I had a regular surgical mask on and sanitized my hands every-time I touched the patient or his surroundings. Ive been placed in isolation but Im asymptomatic.
