Airborne diseases can be transmitted from one individual to another through the air. The pathogens transmitted may be any kind of microbe , and they may be spread in aerosols, dust or droplets. The aerosols might be generated from sources of infection such as the bodily secretions of an infected individual, or biological wastes.
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 ...
Relevant microbes may be viruses, bacteria, or fungi, and they may be spread through breathing, talking, coughing, sneezing, spraying of liquids, toilet flushing or any activities which generate aerosol particles or droplets or generate fomites, such as raising of dust. [13] [14]
Active or symptomatic tuberculosis is spread from person to person through the air through bacterium spores that are released into the air following a cough or sneeze. Some individuals may be infected with the tuberculosis mycobacterium but never display symptoms. [ 27 ]
As a result, the risk of spread from food products or packaging is very low. [81] Public health authorities recommend that people follow practice good hygiene by washing hands with soap and water before preparing and consuming food. [80] [81] The COVID-19 virus has not been detected in drinking water. [82]
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 ...
If a respiratory disease spreads through inhalation, it means that people can lower their risk of infection indoors through sometimes costly methods to clean the air, such as mechanical ...
The bubonic and septicemic forms are generally spread by flea bites or handling an infected animal, [1] whereas pneumonic plague is generally spread between people through the air via infectious droplets. [1] Diagnosis is typically by finding the bacterium in fluid from a lymph node, blood or sputum. [2] Those at high risk may be vaccinated. [2]
