what we need to know about communicable and non communicable diseases
How these diseases spread depends on the specific disease or infectious agent. Some ways in which communicable diseases spread are by: physical contact with an infected person, such as through touch (staphylococcus), sexual intercourse (gonorrhea, HIV), fecal/oral transmission (hepatitis A), or droplets (influenza, TB)
While infectious disease still remains a major problem in many countries, chronic diseases, including such noncommunicable conditions as cardiovascular disease, cancer, diabetes and respiratory disease, are now the major cause of death and disability, not only in developed countries, but also worldwide.
