Contact: Spreads via direct contact with an infected patient or contaminated surface. Contact precautions reduce method of transmission.
Note: Covid-19 may survive on surfaces for 96 hours or longer. Decontaminate surfaces frequently using a diluted bleach solution by mixing 5 tablespoons (1/3 cup) bleach per gallon of water. Clean and disinfect high-touch surfaces frequently medical such as equipment, floors, tables, hard-backed chairs, doorknobs, light switches, phones, tablets, touch screens, keyboards, handles, desks, toilets, sinks. If a separate, designated bathroom is not available, bathrooms should be cleaned and disinfected after each use by personnel wearing best possible PPE, and waste considered hazardous, disposed according to theater hazardous waste policy.
Droplet: Spreads via relatively large liquid particles that settle from the air quickly (within a few feet). Droplet precautions reduce transmission.
Airborne: Spreads of via small liquid particles (aerosols) that remain suspended in the air for prolonged periods of time, traveling longer distances. Airborne precautions reduce transmission.
