Also by contaminated water and food
By vectors like mosquitoes and flies spread malaria and all.
Hope now you doubt is clear

Answer:
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.
