Final answer:
The type of disease transmission discussed is Direct transmission, typical for pathogens like Treponema pallidum and Neisseria gonorrhoeae, which require close physical contact or sexual contact to spread from one person to another.
Step-by-step explanation:
The type of disease transmission described in the question, which involves the transfer of pathogens from one person to another and is typical of fragile pathogens such as Treponema pallidum (cause of syphilis) and Neisseria gonorrhoeae (cause of gonorrhea), is Direct transmission. This mode of transmission typically requires direct contact between mucous membranes or their secretions, especially in the form of sexual contact, to spread diseases. In contrast, other modes of transmission, such as vehicle-borne, airborne, fomite, or vector, involve either the environment, inanimate objects, or other organisms to facilitate the transfer of pathogens.
Summary Direct contact is the route of transmission for infections that cannot survive long outside a host, requiring close personal interactions for the disease to spread, such as sexually transmitted infections.
