What term means a microorganism leaves its reservoir?

Explanation:
The concept being tested is how a microorganism leaves its source to spread to others, which is described by the portal of exit. The exit portal is the route the pathogen uses to leave its reservoir or host—examples include the respiratory tract during coughing or sneezing, blood from a wound, or any bodily excretion. This term precisely captures the act of departure from the source, which is why it’s the best fit here. In contrast, an entry portal would be where the pathogen enters a new host, transmission refers to the process of spreading from one host to another, and reservoir is simply the source environment or organism where the microbe resides.
