(a) Above 10 years

(b) Below 5 years

(c) Adults

(d) Above 60 years

The question was posed to me during an interview.

I need to ask this question from Bacterial Diseases in Humans-1 in section Human Health and Disease of Biology – Class 12

Answer 1

The correct option is (b) Below 5 years

To explain I would say: Diphtheria commonly affects children below the age group of 5 years. Its symptom includes sore throat, chills with mild fever, vomiting and headache. Throat or tonsils show a grey membrane which may spread down and cause hoarseness and difficulty in breathing.
