PATHOLOGY

Detailed explanation-1: -Many clinically important airborne diseases are caused by a variety of pathogens, including bacteria, viruses, and fungi. These organisms may be transmitted through sneezing, coughing, spraying of liquids, the spread of dust, talking, or any activity that results in the generation of aerosolized particles.

Detailed explanation-2: -Use Airborne Precautions for patients known or suspected to be infected with pathogens transmitted by the airborne route (e.g., tuberculosis, measles, chickenpox, disseminated herpes zoster). See Guidelines for Isolation Precautions for complete details.

Detailed explanation-3: -diseases (ATDs), such as tuberculosis and measles, are transmitted by infectious particles or droplets through inhalation or direct contact with mucous membranes in the respiratory tract or eyes. ATDs that spread via the airborne route are called airborne infectious diseases (AirID).

Detailed explanation-4: -They can stay airborne for an extended period of time before settling on a surface or landing on a nearby person. Aerosols contain fewer infectious virus particles because of their small size. Scientists don’t yet know how many particles of SARS-CoV-2-the virus that causes COVID-19-are needed to infect someone.
