A lifeless object known as a fomite is often involved in disease transmission. The object may be a  towel, cup, or eating utensil. Transmission can also be effected by droplet nuclei, bits of mucus and  saliva that spread between individuals.  Vectors are living things. Arthropods such as mosquitoes, flies, and ticks may carry pathogens on  their body parts, in which case they are mechanical vectors. If the arthropod is infected and transmits  the organism in its saliva or feces, it is a biological vector.  Vehicles are lifeless objects such as food, water, and air. Water may be contaminated by human  feces, while food is often contaminated by pathogens from the soil. Air can be a vehicle for  transmission for droplet nuclei in such diseases as tuberculosis and common colds.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
