The World's Most Destructive Infectious and Parasitic Diseases (2009) Lower respiratory tract infections Diarrheal diseases HIV/AIDS Tuberculosis Malaria
Lower respiratory infections Deaths/year: 4.2 Million Affect the trachea, lungs and bronchi Cases of pneumonia make up the vast majority of debilitating lower respiratory infections.
Diarrheal diseases Deaths/Year: 2.2 million Most commonly caused by gastrointestinal infections, result in loose stool and can cause dehydration and sometimes death. Cholera and dysentery are both common diarrheal diseases.
HIV/AIDS Deaths/Year: 2 million AIDS, or acquired immune deficiency syndrome, is a life-threatening, infectious disease caused by HIV, a retrovirus that attacks the body's immune system and impairs its ability to fight disease.
Tuberculosis Deaths/Year: 1.5 million A chronic bacterial infection that spreads through the air and primarily affects the lungs. If not treated properly, tuberculosis can affect other organs and lead to death.
Malaria Deaths/Year: 890,000 A parasitic disease transmitted between humans by the bite of an infected Anopheles mosquito. The disease causes flu-like symptoms and attacks of fever and chills.
MDC – infectious diseases pose small risk LDC and LLDC – cause a high number of deaths WHY? – Poor sanitation – Unsafe drinking water – Poor access to health care (hospitals, doctors/nurses, medicine, vaccinations) – Lack of health education
