Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi. Infectious diseases can be spread, directly or indirectly, from one person to another. 
Infectious diseases are a leading cause of death worldwide, particularly in low income countries, especially in young children.
Three infectious diseases were ranked in the top ten causes of death worldwide in 2016 by the World Health Organization. They are lower respiratory infections (3.0 million deaths), diarrheal diseases (1.4 million deaths), and tuberculosis (1.3 million deaths). HIV/AIDS, which was previously on the list, has dropped from the global list of the top ten causes of death (1.0 million deaths in 2016 compared with 1.5 million in 2000), but it is still a leading cause of death in low income countries. Another infectious disease, malaria, accounts for a top cause of death in low income countries.
Approximately half of all deaths caused by infectious diseases each year can be attributed to just three diseases: tuberculosis , malaria , and AIDS . Together, these diseases cause over 300 million illnesses and more than 5 million deaths each year.
