Answer :
Final answer:
A substance that transports pathogens without getting infected itself is called a fomite, which differs from a vector that is an organism capable of transmitting pathogens. Vectors are typically insects or arthropods that carry diseases to new hosts, either through mechanical or biological means. correct answer is 1) Vector .
Explanation:
An inanimate object or substance capable of transporting pathogens from one medium or individual to another is referred to as a fomite. The correct answer to the given question is not listed among the options. Instead, vectors are typically living organisms, such as arthropods (e.g., mosquitoes and ticks), that can transmit pathogens from one host to another, either as mechanical vectors or biological vectors. A mechanical vector carries the pathogen on its body without getting infected, whereas a biological vector is an organism that becomes infected with the pathogen and is then capable of transmitting the infection through biting another host.
Preventing diseases that are spread by vectors may involve avoiding contact with them, wearing appropriate clothing, and using insect repellent. When it comes to pathogens transmission, understanding the role of vectors is crucial for effective disease control and prevention strategies.
