FAQs prepared by doctor

Q1.  How long does it take for the illness to develop?
The illness may develop up to seven days after contact with the bacteria
Q2.  I cared for a diphtheria patient in hospital. Should I be treated?
Any health care workers who may have been involved in treating a patient with diphtheria may also require a swab test, antibiotics and immunization against the infection. However, School classroom contacts and those who share the same room at work are not normally considered to be close contacts. A doctor or nurse will take a swab test from your nose and you will be given a prescription for a course of antibiotics. It is important to finish the whole course of treatment. You will also receive a booster vaccination if required.
Q3.  Does the vaccine offer good protection against diphtheria?
Yes. Diphtheria vaccine is given as part of a combined diphtheria, tetanus, pertussis, Hib (Haemophilus influenzae type b) and polio vaccine, and offers very effective protection against all these diseases.
Q4.  If I have been fully immunized can I still get diphtheria?
  • No, the vaccine protects you against the diphtheria toxin. However, immunization does not prevent you from carrying the bacteria.
  • Most cases occur in people who are unvaccinated or inadequately immunized.
