Overview
Diphtheria is found worldwide but is rare in the United States. Diphtheria causes significant illness and death in developing countries where vaccination coverage is low.
Epidemiology and Demographics
Incidence
Case Fatality Rate
- The overall annual case fatality rate for diptheria ranges between 5 and 10%.[3]
- The annual case fatality rates for patients that are younger than 5 or older than 40 years old tend to be higher, ranging up to 20%.
Age
- Diphtheria most commonly affects children under the age of 5 years old and without vaccination.[4]
- Individuals over 50 years old are particularly susceptible to diphtheria, particularly those over 70 years old, due to the higher probability of lacking vaccination.[5][6]
Gender
- There is evidence that women are more prone than men to diphtheria infection due to lower antitoxin responses to vaccination, requiring more frequent booster administrations.[7]
Race
Developed and Developing Countries
- Diphtheria is found worldwide; countries with endemic diphtheria are shown in Table below.
- During the 1990s, large epidemics occurred in the newly independent states of the former Soviet Union.
- More recently in the Americas, diphtheria outbreaks have occurred in Haiti and the Dominican Republic.
- Diphtheria is uncommon in industrialized countries because of longstanding routine use of DTP (diphtheria and tetanus toxoids and pertussis vaccine).
- Diphtheria is rare in the United States; the last case occurred in an elderly traveler returning from Haiti in 2003. Diphtheria causes significant illness and death in developing countries where vaccination coverage is low.
- By 1998, according to Red Cross estimates, there were as many as 200,000 cases in the Commonwealth of Independent States, with 5,000 deaths.
- This was so great an increase that diphtheria was cited in the Guinness Book of World Records as "most resurgent disease".
- Diphtheria is rare in the United States; the last case occurred in an elderly traveler returning from Haiti in 2003. Diphtheria causes significant illness and death in developing countries where vaccination coverage is low.
