Top Ten Deadliest Diseases


Deadliest diseases in the world. Top ten most deadly diseases in human history ranked by most deaths.

10:

Number ten: tuberculosis. Tuberculosis is an airborne disease that affects the lungs caused by the Mycobacterium tuberculosis bacteria. It causes 900,00 deaths every year. The majority of these deaths occur in poor, less-developed countries.

9:

Number nine: preterm birth complications, or premature births. About 1.1 million lives are lost every year due to prematurity and low birthweight complications. 75% of these deaths happen within the first week of the child’s life.

8:

Number eight: diabetes. Diabetes affects insulin production and use and comes in two forms–type 1 and type 2 diabetes. It kills about 1.5 million people every year.

7:

At number seven we have diarrheal diseases. Diarrhea lasting more than a few days is fatal because of the body losing too much water and salt. Therefore, death is due to dehydration. Diarrheal diseases kill 1.5 million people every year, down from 2.2 million people in 2002.

6:

Number six is HIV/AIDS. Human immunodeficiency virus (HIV) is a virus that attacks the immune system, which can cause acquired immunodeficiency syndrome, a chronic, life-threatening condition or illness. Since the start of the pandemic, 39 million lives have been lost while another 1.5 million are lost every year, or 2.7% of deaths worldwide.

5:

At number five we have trachea, bronchus, and lung cancer. These are all respiratory cancers caused by smoke, second-hand smoke, and environmental toxins. They kill 1.6 million people every year, or about 2.9% of deaths worldwide.

4:

At number four we have lower respiratory infections. With 3.1 million deaths yearly, lower respiratory infections are diseases that affect the lungs, which include bronchitis, influenza (flu), and pneumonia.

3:

Starting of our top 3 of deadliest diseases is chronic obstructive pulmonary disease (COPD). COPD are chronic lung diseases that make it difficult to breathe. They include bronchitis and emphysema and are mainly caused by tobacco. They kill 3.1 million people per year, or 5.6% of deaths worldwide.

2:

Number two in our deadliest diseases list is a stroke. Strokes occur when an artery in the brain is blocked or leaked, depriving the brain of oxygen and killing its cells within minutes. It kills about 6.7 million people every year, making up 11.9% of deaths worldwide. In the U.S. one person dies every four minutes from a stroke, causing 130,000 deaths per year.

1:

And at number one, we have coronary artery disease (CAD). Coronary artery disease, also known as ischemic heart disease, is when the blood vessels that supply blood to the heart become narrowed due to a buildup of plaque from smoking, high cholesterol, etc. This causes bloodflow to the heart to become restricted, which starves it of oxygen and vital nutrients necessary for it to pump properly. This is what causes heart attacks. Heart disease is responsible for 7.4 million deaths per year, or 13.2% of deaths worldwide.
