Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary medicine. The relevant infectious agent may be viruses , bacteria , or fungi , and they may be spread through breathing, talking, coughing, sneezing, raising of dust, spraying of liquids, flushing toilets , or any activities ...
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 ...
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
The World Health Organization and around 500 experts have agreed for the first time what it means for a disease to spread through the air, in a bid to avoid the confusion early in the COVID-19 ...
The WHO concluded that airborne transmission occurs as sick people exhale pathogens that remain suspended in the air, contained in tiny particles of saliva and mucus that are inhaled by others.
Contagious diseases can spread to others through various forms. Four types of infectious disease transmission can occur: . contact transmission, which can be through direct physical contact, indirect contact through fomites, or droplet contact in which airborne infections spread short distances,
This hematogenous transmission can also spread infection to more distant sites, such as peripheral lymph nodes, the kidneys, the brain, and the bones. [13] [92] All parts of the body can be affected by the disease, though for unknown reasons it rarely affects the heart, skeletal muscles, pancreas, or thyroid. [93]
What the CDC says about airborne transmission. According to the Centers for Disease Control and Prevention, monkeypox can spread through “respiratory secretions” when an infected person coughs ...
