How are diseases in the 1970s carried?

Answer 1

Diseases in the 1970s were carried and transmitted in the same ways they are today (bacteria, bacteria and parasites only have so many ways to enter the body). These include through these primary methods:

1. intake of air (example TB, tuberculosis) - breathing, coughing, sneezing
2. from touching objects that have a live virus or live bacteria
3. from human to human touch, most often a handshake (eg from the hands)
4. from animal waste
5. drinking contaminated water
6. eating contaminated food
7. sexual transmission
8. contamination of a wound even in surgery
