Overview
Worldwide, an estimated 10,000 cases of trichinosis occur every year.[1] Trichinosis is rare in developed countries, but it is still common in developing countries.
Epidemiology and demographics
Incidence
- Worldwide, an estimated 10,000 cases of trichinosis occur every year.
- During 2008–2012, a total of 90 cases of trichinosis were reported in the USA.
- In the USA, the average of trichinosis is approximately 15 cases per year.[1]
Mortality Rate
- The mortality rate of trichinosis is approximately 0.2% worldwide.[2]
Age
- Trichinosis most commonly affects individuals 30 to 39 years of age.[3]
- Although infections also occur in children and adolescents, the predominance of infection in adults probably results from culture-driven food behavior.
- Improperly cooked or prepared meat dishes may be more commonly eaten at adult-oriented events, especially among alcohol consumers.[4]
Gender
- Men are more commonly affected with trichinosis than women.[3]
Race
- There is no racial predilection to trichinosis.
Developed Countries
- In the US and EU, the overall incidence of trichinosis is low given the improved pig-raising practices in the pork industry, commercial and home freezing of pork, and public awareness of the danger of eating raw or undercooked meat products.
- The number of cases associated with raw or undercooked wild game meats has remained relatively constant over time.[1][5][6]
Developing Countries
- Trichinosis is common in developing countries where meat fed to pigs is either raw or undercooked.[7]
- In South America, outbreaks in Argentina are common.
- Incidence data from developing countries are limited.
- In Asia, the majority of the outbreaks were reported from Thailand, Laos, and Vietnam, and the northern mountainous regions among the indigenous people who practice free-roaming pig husbandry.[4]
