HEYAAAA,,,
1. Infectious diseases are caused by pathogens such as bacteria, viruses, fungi and parasites.
2. These pathogens can enter the body through the air we breathe, the food and drink we consume or through openings in the skin, such as cuts.
3. Non-infectious diseases aren't caused by pathogens and can't be spread person-to-person.
4. There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases.
5. Some diseases can be cured. Others, like hepatitis B, have no cure.
