Airborne pathogens or allergens typically enter the body via the nose, throat, sinuses and lungs. Inhalation of these pathogens affects the respiratory system and can then spread to the rest of the body. Sinus congestion, coughing and sore throats are examples of inflammation of the upper respiratory airway.
A mechanical vector picks up an infectious agent on the outside of its body and transmits it in a passive manner. An example of a mechanical vector is a housefly, which lands on cow dung, contaminating its appendages with bacteria from the feces, and then lands on food prior to consumption. The pathogen never enters the body of the fly.
The main "highways" for the spread of pathogens in the home are the hands, hand and food contact surfaces, and cleaning cloths and utensils (e.g. fecal–oral route of transmission). Pathogens can also be spread via clothing and household linens, such as towels. Utilities such as toilets and wash basins were invented to deal safely with human ...
That’s because bacteria is more likely to be transferred from wet skin than from dry skin. So make sure you’re also drying hands thoroughly after hitting the sink.
Bacteria pneumonia can spread to the bloodstream and cause sepsis, which is extremely dangerous and can be quickly fatal. And pockets of pus can form inside or around the lungs, and they may need ...
Kids heading back to school are entering a contagion hot zone. But there are ways to keep them healthy and prevent a slew of unscheduled sick days.
Various forms of isolation exist, and are applied depending on the type of infection and agent involved, and its route of transmission, to address the likelihood of spread via airborne particles or droplets, by direct skin contact, or via contact with body fluids. [citation needed]
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.
