What Kills The Most Humans Every Year

It may seem like a strange question, but it is worth knowing the answer to. What is the cause of death that kills the most humans per year? More than half of all deaths worldwide are caused by non-communicable diseases like heart disease and cancer.

What is the leading cause of death?

Heart disease is the leading cause of death in the world. It kills more people every year than any other disease, including HIV, lung cancer, and diabetes.

Prevention and treatment for deadly diseases

One of the most effective ways to save lives is to keep deadly diseases from spreading. Some of these diseases are mosquito-borne viruses like Zika, malaria, Dengue fever, and West Nile. Diseases can spread when people get bitten by an infected insect or contract them through sexual contact with someone who is infected. To save lives for these kinds of disease, researches work on prevention and treatment methods.

The importance of knowing your risk factors

Understanding your risk factors is the first step in prevention. Knowing your risk factors will help you understand what needs to be done to lower your risk of heart attack, stroke, and other medical problems. For example, if you are at high risk for heart disease, there are steps you can take to decrease that risk; like eating healthy with an appropriate diet or exercising on a regular basis.


The World Health Organization reports that malaria is the leading cause of death of humans, killing more than 1 million people every year. The organization also reports that 3.2 billion people are at risk for malaria, with 91% of deaths occurring in sub-Saharan Africa. Malaria occurs due to a mosquito bite. Individuals who live near water sources are at greater risk for getting bitten by mosquitoes.
