Annual deaths number from communicable diseases 2021

Tuberculosis is one of the deadliest communicable diseases worldwide, causing around 1.4 million deaths per year. Communicable diseases, also known as infectious diseases, are spread from person to person either directly or indirectly, such as through an insect bite or ingesting contaminated food or water. Some of the deadliest communicable diseases include HIV/AIDS, malaria, hepatitis C, cholera, and measles.

Tuberculosis

Tuberculosis is an infectious disease that affects the lungs. Tuberculosis disproportionately impacts the poorer, less developed countries of the world, such as in Africa and Southeast Asia. India reports the highest number of deaths from tuberculosis worldwide.

HIV/AIDS

Although deaths from HIV/AIDS have decreased over the last few decades, there were still around 630,000 AIDS-related deaths in 2023. Like many other communicable diseases, HIV/AIDS impacts developing regions more than the developed world. By far, the highest number of AIDS deaths come from Africa and Asia Pacific. Advancements in HIV treatment now allow those infected to live long and relatively normal lives, but access to treatment varies greatly.
