Follow standard precautions to help prevent the spread of blood-borne pathogens and other diseases whenever there is a risk of exposure to blood or other bodily fluids. Standard precautions include maintaining personal hygiene and using personal protective equipment (PPE), engineering controls, and work practice controls among others. [ 17 ]
Bloodstream infections (BSIs) are infections of blood caused by blood-borne pathogens. [1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the host organism to ...
A transfusion transmitted infection (TTI) is a virus, parasite, or other potential pathogen that can be transmitted in donated blood through a transfusion to a recipient. The term is usually limited to known pathogens, but also sometimes includes agents such as simian foamy virus which are not known to cause disease.
Candida albicans infection; Candida parapsilosis infection; Cytomegalovirus infection; diphtheria; human coronavirus infection; respiratory distress syndrome; measles; meconium aspiration syndrome
List of bacterial vaginosis microbiota: Bacterial vaginosis: Gram stain and whiff test Metronidazole or clindamycin: No Bacteroides species Bacteroides infection No Balantidium coli: Balantidiasis: microscopic examination of stools, or colonoscopy or sigmoidoscopy Tetracycline, metronidazole or iodoquinol: No Bartonella: Bartonellosis ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Once pathogens attach to host cells, they can cause direct damage as the pathogens use the host cell for nutrients and produce waste products. [23] For example, Streptococcus mutans, a component of dental plaque, metabolizes dietary sugar and produces acid as a waste product. The acid decalcifies the tooth surface to cause dental caries. [24]
The hazard in a health care setting is exposure to blood, saliva, or other bodily fluids or aerosols that may carry infectious materials such as Hepatitis C, HIV, or other blood borne or bodily fluid pathogen. PPE prevents contact with a potentially infectious material by creating a physical barrier between the potential infectious material and ...
