Do you know what are the top 3 deadliest diseases in the world? Do you know that some diseases can take your life in just a few days? And some diseases might already be inside you, but you don’t even notice any signs!

Most 3 Infectious Deadliest Diseases in the World :- Malaria, HIV/AIDS, Tuberculosis (TB)

Place of Malaria: Why Malaria is 3rd most deadly disease

In the year 2020, 241 million  malaria cases were reported, out of which 627,000 deaths occurred.

Malaria is caused by a type of parasite and spreads through the bite of a female Anopheles mosquito. If you have ever visited Sub-Saharan regions or tropical areas, you might know a lot about malaria.

94% of malaria deaths occur in Sub-Saharan Africa, and it affects not only adults but also children under the age of 5.

Why HIV/AIDS at 2nd place took 32 million lives?

HIV, or Human Immunodeficiency Virus, is a deadly virus that attacks your immune system. If not treated on time, it can turn into AIDS.

HIV/AIDS is a serious public health issue, which has affected 75 million people worldwide and has been responsible for nearly 32 million deaths.

In the year 2022 alone, 0.63 million deaths were caused by HIV/AIDS, mainly affecting people between the ages of 15 and 59.

Why Tuberculosis TB at Fist place as Deadliest Infectious Disease?

Tuberculosis, or TB, is a disease caused by the Mycobacterium Tuberculosis bacteria, which primarily affects the lungs. TB can also occur in other parts of the body, which is called extrapulmonary TB.

In 2010, around 10 million people got TB, and nearly 1.5 million people died because of it. In 2022, after COVID-related deaths, TB caused the most deaths, with around 1.3 million people losing their lives.

In all three diseases, immunity is so severely damaged that it doesn’t naturally recover, which leads to a higher death rate. However, by staying aware and educating people about prevention, these diseases can be prevented and treated.
