American Roentgen Ray Society Images of Listeriosis epidemiology and demographics
The annual incidence of listeriosis in the United States is approximately 0.2-0.3 cases per 100,000 individuals. The incidence of listeriosis is higher among females (especially pregnant women), neonates, elderly individuals, and Hispanic individuals. Listeriosis has a worldwide distribution in both developed and developing countries.
Epidemiology and Demographics
- The annual incidence of listeriosis in the United States is approximately 0.2-0.3 cases per 100,000 individuals.
- The CDC estimates that approximately 1600 illnesses and 260 deaths due to listeriosis occur annually in the United States.
- Compared with the 1980s, the incidence of listeriosis significantly declined by 42% in the past 10 years. The incidence of listeriosis is thought to have plateaued.
- The global annual incidence of listeriosis is estimated at 0.7 per 100,00 cases.
- The global incidence of listeriosis among those >70 years of age is 2.1 per 100,00 cases.
- The incidence among pregnant women is 12.0 per 100,000 cases.
- Since listeriosis affects pregnant women (approximately 25% to 30% of all cases), women are more likely to develop listeriosis compared with men.
- There is no predilection to listeriosis when men and non-pregnant women are compared.
- Racial predilection to the development of listeriosis is unconfirmed.
- Pregnant Hispanic women are thought to be at higher risk of developing listeriosis, but the association with the disease may be due to pregnancy or due to ethnicity.
