Hello @Mariahareceli,
How are you doing? The most common fatal diseases in the US are known as Chronic Diseases. Chronic Diseases are known as Heart Diseases, strokes, cancer, type 2 diabetes, obesity, and arthritis. Those conditions are the most common, and sadly, fatal.
I hope I have helped you, and contact me if you need more assistance.
Thank you,
Darian D.
