When the body is infected with a pathogen, the immune system recognizes the foreign bodies and raises the temperature to try and kill of the pathogens. This causes a fever, which is an increase in body temperature above 98.6 degrees Fahrenheit.
In medicine, the locus where a pathogen can enter would be any part of the body or surface that is moist. This includes the eyes, the nose and the mouth.

Colds, influenza and measles are all three caused by different kinds of viruses.
Through your nose or throat.
A pathogen can enter a new reservoir through various routes, such as direct contact with infected animals or consumption of contaminated food or water. Once in the new reservoir, the pathogen may adapt to the new host species and establish infection cycles within that population.
