Which of the following is a fomite?
A
A person infected with influenza
B
A mosquito carrying malaria
C
Airborne droplets from a sneeze
D
A doorknob contaminated with bacteria
Verified step by step guidance1
Understand the definition of a fomite: A fomite is an inanimate object or surface that can carry and transmit infectious agents, such as bacteria or viruses, to a new host.
Analyze each option to determine if it is an inanimate object or a living organism: A person infected with influenza is a living host, not a fomite.
A mosquito carrying malaria is a living vector, not a fomite, because it actively transmits the pathogen through biting.
Airborne droplets from a sneeze are particles suspended in the air, not objects, so they are not fomites.
A doorknob contaminated with bacteria is an inanimate object that can harbor pathogens and facilitate their transmission, fitting the definition of a fomite.
