How do epidemics affect the economy?
Concern over the spread of even a relatively contained outbreak can lead to decreased trade. Travel and tourism to regions affected by outbreaks are also likely to decline.

What are the 3 main ways infection can get into the body?
This is the way that the pathogen enters the body of the potential host. Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.
How do infections enter the body?
Some infections are spread directly when skin or mucous membrane (the thin lining of parts of the body such as nose, mouth, genitals) comes into contact with the skin or mucous membrane of an infected person. Infections may be spread indirectly when the skin comes in contact with a contaminated object.
