Top 10 Most Deadliest/Dangerous Diseases in the World

Diseases have ridden the human species since its very conception. Through whatever medium, diseases have always plagued us humans and made us suffer in many ways. Deadly, and sometimes deceptive, these diseases have reached our countdown of the top 10 deadliest diseases.

10. Lung Cancer

Lung cancer has been proven to be the most deadly type of cancer in male and females, rising up to a death toll that surpasses colon, breast and prostate cancers every year.

9. Malaria

It is self evident how much we hate those summer days when those annoying little mosquitoes eat away at us. Though it is very surprising at how deadly these tiny creatures can be. Spreading parasites from human to human, and infecting us with malaria. Once the malaria matures inside our bloodstream, the malaria cells start to multiply at an alarmingly high rate. Malaria is held accountable for more than 1 million people dying every year.

8. Tuberculosis

Tuberculosis is a deadly disease that is well known for its terrible symptoms. High fevers, mucous build up, fatigue, and excessive sweating are all symptoms of TB. TB usually occurs with people who have weakened immune systems, such as people infected with AIDS or the elderly. TB is usually caught by living in unhygienic conditions, maintaining an insufficient diet, or living around someone else who has TB.

7. Diarrheal Diseases

The usual diarrhea case can be seen as harmless and at times funny. That’s only because it may last at max a day or two. Yet when it stays with you for weeks, or months, it becomes a chronic disease with the potential of shutting down your immune system. Chronic Diarrhea is also the main cause of dehydration as the important bodily fluids are constantly being removed from the human system.

5. Chronic Obstructive Pulmonary Disease

More commonly known as COPD, this is a lung disease that branches off into two different categories. One is known as Chronic Bronchitis which makes the act of respiration a very hard task. Instilling a long term cough that is filled with mucous. The other branch is known as Emphysema which is the steady deterioration of the lungs. Both sound equally horrible diseases, and both have the same prescription; stay away from cigarettes.


HIV is the un-evolved form of AIDS which weakens our immune systems down to a very negligible amount. HIV attacks the T-Cells in your body which otherwise have the occupation of fighting infectious diseases. In this case, the T-Cells lose the battle.
