Answer :
Final answer:
Cross contamination refers to the process where pathogens get transferred from one surface to another, potentially leading to infections. This can occur via direct contact between individuals or via indirect contact through an intermediate contaminated object known as a fomite.
Explanation:
The transfer of pathogens from one surface to another is referred to as cross contamination. This transmission of harmful microorganisms can occur through a variety of methods, but the most common is through direct or indirect contact. Direct contact transmission occurs when a person physically contacts another individual hosting a pathogen. This transfer can happen through activities like touching, kissing, or sexual activity.
Alternatively, indirect contact occurs when a person or object carrying a pathogen comes into contact with an inanimate object, contaminating it. When another individual makes contact with this contaminated surface and then touches a susceptible area of their body, such as a mucous membrane, cross contamination occurs. The objects involved in this transfer process are known as fomites and can include items like doorknobs, towels, or unsterilized medical equipment.
