Question

which action can best limit the transmission of pathogens by direct contact? a. drinking only clean water b. using mosquito netting c. washing hands d. washing vegetables

Explanation:

Direct contact transmission of pathogens often occurs through hands touching contaminated surfaces or other people. Washing hands can remove pathogens from hands, reducing the chance of transmission. Drinking clean water helps avoid water - borne pathogens, using mosquito netting prevents vector - borne transmission, and washing vegetables reduces food - borne pathogens. But only hand - washing directly addresses direct contact transmission.

Answer:

C. Washing hands
