The transmission of COVID-19 is the passing of coronavirus disease 2019 from person to person. COVID-19 is mainly transmitted when people breathe in air contaminated by droplets/aerosols and small airborne particles containing the virus. Infected people exhale those particles as they breathe, talk, cough, sneeze, or sing.
Common infections that spread by airborne transmission include SARS-CoV-2; [14] measles morbillivirus, [15] chickenpox virus; [16] Mycobacterium tuberculosis, influenza virus, enterovirus, norovirus and less commonly other species of coronavirus, adenovirus, and possibly respiratory syncytial virus.

Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
The U.S. Centers for Disease Control and Prevention (CDC) on Monday sowed confusion over its stance on the airborne transmission of the coronavirus.
Different diseases spread in different ways; some spread by only some of these routes. For instance, fomite transmission of COVID-19 is thought to be rare while aerosol, droplet and contact transmission appear to be the primary transmission modes, as of April 2021. [3] Coughs and sneezes can spread airborne droplets up to ~8 meters (26 ft).
Therefore, disease isolation is an important infection prevention and control practice used to protect others from disease. [6] Disease isolation can prevent healthcare-acquired infections of hospital-acquired infections (HCAIs), reduce threats of antibiotic resistance infections, and respond to new and emerging infectious disease threats ...
Separate from "barrier precautions" and "standard precautions" are "airborne precautions", a protocol for "infectious agents transmitted by the airborne route", like with SARS-CoV and tuberculosis, requiring 12 air changes per hour for new facilities, and use of fitted N95 respirators. These measures are used whenever someone is suspected of ...
Tuberculosis is back to being the leading infectious disease killer across the globe, surpassing COVID-19, according to a recent report from the World Health Organization.. Nearly 8.2 million ...
