Question

Which route is NOT a typical example of direct transmission?

Options

• Transfer via blood and other body fluids

• Direct physical contact through touch or skin contact

• Droplet infection by coughing or sneezing at close range

• Vector-borne transmission by mosquitoes

Answer 1

Vector-borne transmission by mosquitoes is an indirect transmission route because it involves an intermediate agent (the insect vector) to carry the pathogen. Direct transmission routes include droplet infection, physical contact, blood transfer, and other methods that do not require intermediate agents or vectors.
