7. Diabetes Mellitus

Diabetes is due to either the pancreas not producing enough insulin or the cells of the body not responding properly to the insulin produced

In 2012, about 1.5 million people died from diabetes-related causes, according to WHO. People in low to middle income countries are more likely to die from complications of diabetes.

 

6. HIV/AIDS

AIDS is caused by HIV, which is an abbreviation for Human Immunodeficiency Virus. The infection caused by HIV weakens the immunity of a person to the extent that he cannot fight even simple diseases like cold. When most of the T-cells or CD4 cells of the human body get killed, full blown AIDS is developed.

Since the start of the pandemic, almost 39 million people have died due to HIV/AIDS. In 2013, about 1.5 million people lost their lives to AIDS. That’s about 2.7 percent of deaths worldwide.

6. HIV/AIDS

By the end of 2012, 35.3 million people around the world were infected with HIV. Every day, about 5,700 more become infected.

Rates vary dramatically by geographical location. HIV is rampant in sub-Saharan Africa, where almost one in 20 adults has it. The region is home to 70 percent of all people who have HIV. Sadly, it’s also home to 91 percent of the HIV-positive children in the world.
