Verified step by step guidance

1. Understand the definitions of each term provided: 'Reservoir', 'Vector', 'Host cell', and 'Fomite'.
2. A 'Reservoir' is an environment or living organism where a pathogen normally lives, grows, and multiplies, serving as a continual source of infection.
3. A 'Vector' is an organism, often an insect, that transmits a pathogen from one host to another but does not usually allow the pathogen to multiply within itself.
4. A 'Host cell' is a cell that a pathogen infects and uses to replicate, but it is not the overall source where the pathogen survives long-term.
5. A 'Fomite' is an inanimate object that can carry pathogens but does not support their multiplication or survival over extended periods.
