In the district of Ghaziabad in the state of Uttar Pradesh, 13 diphtheria cases were registered until October 2021, compared to 14 cases in the entire 2020.
Consequences for the traveler
A booster vaccination is necessary in addition to a basic immunization against diphtheria (together with tetanus, etc.). The optimal time for the booster vaccination for stays in areas with a diphtheria epidemic is unclear. Travelers to countries with diphtheria outbreaks should receive a booster vaccination if the previous booster vaccination is more than 10 years old, as the diphtheria protection is shorter-lasting than the tetanus protection. For high-risk individuals, such as those on humanitarian missions, a shorter interval (e.g., 5 years) should be considered. Please talk to your doctor if you belong to this group.
