True or False: Healthy people do not harbor or transmit bacteria.

The statement that healthy people do not harbor or transmit bacteria is false because all humans, regardless of their health status, carry a variety of bacteria on and within their bodies. The human microbiome plays a crucial role in maintaining health, as beneficial bacteria are essential for processes like digestion and immune function. Moreover, healthy individuals can still transmit bacteria, either through casual contact or respiratory droplets, even if they do not show symptoms of illness. It's important to understand that the presence of bacteria does not inherently correlate with disease; many bacteria are harmless or even beneficial. This capacity to harbor and transmit bacteria is a natural part of human physiology and interactions with the environment.
