Which of the following would be an example of disease transmission via indirect contact?
Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air. If healthy people inhale the infectious droplets, or if the contaminated droplets land directly in their eyes, nose or mouth, they risk becoming ill.
What is the name of the science that deals with when diseases occur and how they are transmitted?
Epidemiology is the study of the determinants, occurrence, and distribution of health and disease in a defined population. Infection is the replication of organisms in host tissue, which may cause disease.
Which of the following is Fomite?
Fomite exposure often involves a secondary route of exposure such as oral or direct contact for the pathogen to enter the host. Examples of fomites include contaminated vehicles, shovels, clothing, bowls/buckets, brushes, tack, and clippers.
Which of the following is a protozoan zoonosis that can be transmitted by direct contact?
Cryptosporidiosis is a worldwide zoonotic parasitic disease that infects a wide variety of animals and humans while infected animals and humans shed a very high number of oocysts. Its transmission occurs through direct or indirect contact with the feces of these shedders.
What is transmission in epidemiology?
Transmission, in the context of infectious disease, implies the passing of a pathogen from one host or reservoir of the pathogen to a new susceptible host. The term transmission is also used for the transfer of genes in genetic diseases.
Which of the following is not an example of a communicable disease?
A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson’s disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer’s disease, cataracts, and others.
Is a catheter a Fomite?
Fomites can also include objects used in clinical settings that are not properly sterilized, such as syringes, needles, catheters, and surgical equipment. Pathogens transmitted indirectly via such fomites are a major cause of healthcare-associated infections (see Controlling Microbial Growth).
Is a thermometer a Fomite?
Fomites include medical and non-medical devices, including sphygmomanometers, thermometers and stethoscopes (Cohen et al.
Which is an example of vehicle disease transmission?
Common vehicle transmission refers to transmission through a contaminated source. Examples include food, medication, intravenous fluid, or shared equipment that transmits infection to multiple hosts. This transmission may result in a large-scale outbreak.
Which of the following is a protozoan zoonosis?
Toxoplasmosis, neosporosis, sarcosporidiosis (sarcocystosis) and trypanosomiasis are the common zoonotic protozoal diseases causing abortion which caused by single-celled protozoan parasites; Toxoplasma gondii, Neospora caninum, Sarcocystis spp and Trypanosoma evansi, respectively.
