Question 2 (6 points) The chain of infection is the means by which a pathogen develops and moves from its original environment to a susceptible host. Match the following terms and their definitions: Question 2 options: The way a pathogen travels. There are two types of transmission and they include direct or indirect. The way the pathogen leaves a reservoir. Places where pathogens live. The organism that a pathogen infects. The way a pathogen can enter a new host. An infectious agent that can cause disease. 1. Pathogen 2. Reservoir 3. Portal of Exit 4. Mode of Transmission 5. Portal of Entry 6. Host

To avoid the spread of communicable diseases we must break the chain of infection. This can be done at each link in the chain. Which of the following match the link in the chain of infection with an appropriate action that breaks the chain of infection at that link?Group of answer choicesPathogen: exercisePortal of entry: avoid touching door knobsPortal of exit: covering your coughTransmission: antibiotics

The route through which a pathogen departs from the host organism is called the of .
