Question

Management of unimmunised contacts of diphtheria is

• A. Antitoxins
• B. Immunoglobins and antitoxin
• C. Erythromycin
• D. Isolation

Answer 1

The correct option is C Erythromycin

Parenteral antibiotic treatment is usually required initially and can be either erythromycin or benzathine penicillin. These can be substituted by equivalent oral formulations once the patient can swallow comfortably. These should be continued to complete a total of 14 days of treatment. The disease is usually not highly contagious after 48 hours of antibiotic therapy.

Therefore, the correct answer is option C.
