What Are The 10 Most Common Diseases?
The World’s Deadliest Diseases
To answer the question of what are the 10 most common diseases in the world, really takes more information than the question gives us. To answer the question of what are the world’s 10 deadliest diseases, while not necessarily pleasant, is a specific enough question to provide quantitative information for.
Many people in the U.S. and from other industrialized countries would probably be able to accurately guess what some of the 10 deadliest diseases in the world are but they will likely be surprised by the answers for others. An oftentimes surprising fact for many is that several of the deadliest diseases are partially preventable and/or easily managed but many people in the world do not have access to quality healthcare and resources that could keep these diseases under control and not a life-threat.
