how would a person develop those diseases that dont spread by contact with a sick person ?

That would depend on the type of disease. For example :
- Deficiency diseases like scurvy, Kwashiorkor, anaemia etc are caused by inadequate diet.
- Inherited diseases like haemophilia are caused by passing of defective genes from parents to offspring
- Degenerative diseases like arthritis are caused by wearing away of organs and tissues usually with age
- Mental diseases like depression and paranoia are caused by brain damage
- Hormonal imbalances cause disorders like hyperthyroidism, diabetes etc.
- Malfunctioning of the immune system causes problems like allergy.
