Final answer:
Inanimate objects contaminated with pathogens that contribute to the spread of infection are known as fomites. Fomites include everyday objects like doorknobs, toys, and towels, which require regular cleaning to prevent disease transmission.
Step-by-step explanation:
Inanimate objects that are contaminated with pathogens and contribute to their spread are referred to as fomites. Unlike vectors, which are living organisms (like ticks and mosquitoes) that transmit pathogens from one host to another, fomites are non-living objects that can harbor disease-causing microbes. Common examples of fomites include doorknobs, toys, or towels. It's essential to maintain a proper level of cleanliness, particularly with items that are frequently used or come into close contact with humans, to prevent the spread of infectious diseases through these fomites.
