Hepatitis B Statistics
Hepatitis B statistics can lead to a better understanding of who the disease affects. Perhaps the most promising hepatitis B statistics involve the decrease in the number of new hepatitis B infections -- from 260,000 in the 1980s to about 73,000 in 2003. Other hepatitis B statistics indicate that the highest rate of the disease occurs in 20- to 49-year-olds.
Following are some key hepatitis B statistics:
- The number of new hepatitis B infections per year has declined from an average of 260,000 in the 1980s to about 73,000 in 2003.
- The highest rate of this disease occurs in 20- to 49-year-olds.
- The greatest decline in hepatitis B has happened among children and adolescents due to routine hepatitis B vaccination.
- About 1.25 million Americans are estimated to be chronically infected with hepatitis B. Of these people, 20 to 30 percent acquired their infection in childhood.
- The overall rate of death from a hepatitis B infection is 1 percent.
- Acute hepatitis B will lead to a chronic (long-term) liver infection in 30 percent to 90 percent of people infected as infants or children and 6 to 10 percent of people who are infected as adolescents and adults. Chronic infection can lead to chronic liver disease, liver scarring (cirrhosis), and liver cancer.
