- A) Horizontal transmission involves the spread of pathogens from one individual to another within the same generation, which can occur through various means such as direct contact, ingestion, or airborne spread. This is different from vertical transmission, which specifically refers to the transmission from parent to offspring, typically from mother to child during pregnancy, birth, or breastfeeding.- B) Most infectious diseases are indeed transmitted horizontally, as this encompasses a wide range of common transmission routes including person-to-person contact, contaminated food or water, and airborne pathogens.- C) Vertical transmission is accurately described as the transfer of a pathogen from a mother to her unborn child or during childbirth. This can occur across the placenta, in the birth canal, or through breast milk.
