  2. Airborne transmission - Wikipedia

    en.wikipedia.org/wiki/Airborne_transmission

    Infected people generate larger droplets and aerosols which can infect over longer distances. A poster outlining precautions for airborne transmission in healthcare settings. It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1]

  3. Respiratory droplet - Wikipedia

    en.wikipedia.org/wiki/Respiratory_droplet

    A respiratory droplet is a small aqueous droplet produced by exhalation, consisting of saliva or mucus and other matter derived from respiratory tract surfaces. Respiratory droplets are produced naturally as a result of breathing, speaking, sneezing, coughing, or vomiting, so they are always present in our breath, but speaking and coughing ...

  4. NIOSH air filtration rating - Wikipedia

    en.wikipedia.org/wiki/NIOSH_air_filtration_rating

    The first part of the filter's classification indicates the series using the letters N, R, or P to indicate the filter's resistance to filtration efficiency degradation when exposed to oil-based or oil-like aerosols (e.g., lubricants, cutting fluids, glycerine, etc.). [17] Definitions and intended use for each series is indicated below. [18]

  5. Aerosol - Wikipedia

    en.wikipedia.org/wiki/Aerosol

    Mist and fog are aerosols. An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. [1] Aerosols can be generated from natural or human causes. The term aerosol commonly refers to the mixture of particulates in air, and not to the particulate matter alone. [2] Examples of natural aerosols are fog, mist or dust.

  6. Common cold - Wikipedia

    en.wikipedia.org/wiki/Common_cold

    Droplet precautions cannot reliably protect against inhalation of common-cold-laden aerosols. Instead, airborne precautions such as respirators, ventilation, and HEPA/high MERV filters, are the only reliable protection against cold-laden aerosols. [38] Isolation or quarantine is not used as the disease is so widespread and symptoms are non ...

  8. Transmission of COVID-19 - Wikipedia

    en.wikipedia.org/wiki/Transmission_of_COVID-19

    The aerosols generated by some AGPs have been measured and found to be less than the aerosols produced by breathing. [69] Less virus (strictly speaking, viral RNA) [ a ] has been found in the air near intensive care unit (ICUs) with COVID-19 patients than near rooms with COVID-19 patients that are not ICUs. [ 70 ]

  9. Pathogen transmission - Wikipedia

    en.wikipedia.org/wiki/Pathogen_transmission

    An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
