The deadliest viruses by death rate

Over the past century, urbanization, changing sexual behavior, a growing world population, and increased mobility have helped viruses to spread.
Here are seven deadly viruses that claim thousands—sometimes even millions—of lives each year.

1.  HIV/AIDS: causes a staggering 1.6-1.9 million deaths every year.


2.   Hepatitis: It has been estimated that hepatitis (all types) causes around a million deaths annually. Hepatitis B accounts for 600,000 deaths and is 50-100 times more infectious than HIV. Additionally, every year there are 350,000 deaths related to hepatitis C and 70,000 deaths related to hepatitis E.


3.  Influenza: Despite the fact that effective and safe vaccines have been available and used for more than 60 years, influenza causes 250,000-500,000 deaths every year. Elderly people and those with chronic medical conditions are at particular risk of developing serious illness.


4.  Human papillomavirus: Although most infections with human papillomavirus (HPV) are not symptomatic, persistent infection can cause cervical cancer. In fact, HPV is the cause of virtually all cervical cancers (99%), which is the second most common cancer in women worldwide. HPV causes 275,000 deaths every year.


5. Rabies: More than 55,000 people die of rabies every year.


6. Dengue fever: Around 50-100 million people are infected every year, resulting in 12,500-25,000 deaths.


7.  Rotavirus: is the most common cause of severe diarrhoea in infants and children globally. Each year there are around 500,000 deaths related to rotavirus.
