The top three deadliest diseases worldwide, based on World Health Organization (WHO) data from 2021, are primarily cardiovascular and respiratory conditions.
The number one killer in the world is cardiovascular disease (CVD), including heart disease and stroke, responsible for about one-third of all global deaths, claiming nearly 18-20 million lives annually, and remains the leading cause across all regions, according to WHO and World Heart Federation. While COVID-19 caused significant deaths in recent years, CVD has consistently held the top spot for decades, with increases seen globally, especially in younger populations.
In a world of conflicting headlines and confusing research, people constantly wonder if there is anything they can do to improve their chances of avoiding the big four diseases—cancer, heart disease, diabetes and dementia/Alzheimer's.
You may assume that the flu or COVID-19 is the world's deadliest infectious disease, but it's actually tuberculosis or TB, and cases of TB continue to rise in Colorado and across the U.S.
Toxic shock syndrome (TSS) is a disease entity characterized by sudden onset fever, chills, vomiting, diarrhea, and rash which can quickly progress to hypotension, multiorgan system failure, and even death.
Medical professionals call high blood pressure, also known as hypertension, the silent killer because it can go undetected for a long period of time and leads to death. Most people who have high blood pressure do not have any symptoms; testing is the only way to determine if someone has it.
Taken together, heart diseases and cancers are the cause of every second death. In red are infectious diseases, which are responsible for around 1-in-7 deaths. These include pneumonia, diarrheal diseases, tuberculosis, HIV/AIDS, and malaria. A smaller share – around 4% – was from neonatal and maternal deaths.
Record numbers of men and women globally are now estimated to have reduced kidney function, a new study shows. Figures rose from 378 million people with the disease in 1990 to 788 million in 2023 as the world population grew and aged, making it for the first time a top 10 cause of death worldwide.

He's talking about a disease that has been around for centuries — cholera — and is rearing its head again in Africa. Over the past three years, cases have more than doubled, with over 230,000 cases and nearly 5,000 deaths so far this year on the continent.
Cardiovascular Disease
CVD is a leading cause of death in Australia, affecting about 5% of the population. Risk factors include high blood pressure, high cholesterol, smoking, obesity, and lack of exercise.
