Incubation period for Campylobacter Jejuni enteritis?

Incubation period for Campylobacter Jejuni enteritis?

• A. Mean 1 day
• B. Mean 3 days; range 1-7 days
• C. Mean 5 days
• D. Mean 7 days

Answer: (B)

Campylobacter jejuni enteritis tends to start a few days after exposure, with most cases beginning around the third day. The option that states a mean of 3 days and a range from 1 to 7 days matches this typical pattern: a central tendency near 3 days and some variability that can include onset as early as 1 day or as late as about a week. The other choices imply a shorter or longer average onset than is commonly seen, which doesn’t fit the usual timing. Remember, incubation period is the time from exposure to first symptoms, and for Campylobacter this interval generally falls in roughly a 2–5 day window, with some cases outside that range.
