Diphtheria is coming back with vengeance in parts of Asia where it had been well controlled. Malaysia and Vietnam has reported several cases of Diphtheria in last two months along with Kerala state in south India. There has been 5 deaths in Malaysia, 3 in Vietnam and 2 in Kerala. Both in Kerala and Malaysia, adults some as old as 65, are among suspected cases.
All three areas had similarly good control of Diphtheria for several years now , with only a handful of cases yearly and no deaths. In Malaysia and Kerala, religion based superstitions about vaccinations was found to be a major driving factor for poor vaccination coverage and there by reemergence of the disease. In Vietnam too, the propagation of myths about vaccines has reduced its acceptance.
