What type of disease transmission bypasses the mouth, nose, or eyes?

Parenteral transmission refers to the delivery of pathogens directly into the body through routes other than the digestive system. This can occur through injections, bites, or through breaks in the skin, which allows microorganisms to enter the bloodstream or underlying tissues without passing through the mouth, nose, or eyes.

In a clinical context, parenteral transmission is particularly important in phlebotomy, where bloodborne pathogens can be transmitted through contaminated needles or other sharp instruments. This method of transmission is notable because it can introduce pathogens directly into the body’s circulatory system, which can lead to more serious infections as opposed to oral or respiratory routes that typically first encounter mucosal barriers.

Other types of transmission mentioned, like direct contact, indirect contact, and aerosol, involve exposure to pathogens through different routes such as physical contact, environmental surfaces, or respiratory droplets, which do involve the mouth, nose, or eyes in their pathways of transmission.
