Social distancing is a set of nonpharmaceutical infection control actions intended to stop or slow down the spread of a contagious disease. The objective of social distancing is to reduce the probability of contact between persons carrying an infection, and others who are not infected, so as to minimize disease transmission, morbidity and ultimately, mortality.

Social distancing is most effective when the infection can be transmitted via droplet contact (coughing or sneezing); direct physical contact, including sexual contact; indirect physical contact (e.g. by touching a contaminated surface such as a fomite); or airborne transmission (if the microorganism can survive in the air for long periods).
