What is the incubation period for Cryptosporidium infection?

The incubation period is the time from ingesting Cryptosporidium oocysts to the onset of symptoms. For cryptosporidiosis, this window is typically around a week, but it can range from about 1 to 12 days after exposure, with a common median near 7 days. This makes the broad 1–12 day range the best fit because it captures both the early and typical onset, whereas shorter periods like 2–5 days miss many cases, longer windows such as 7–14 or 14–21 days exceed what’s usually observed. Individual factors like the infectious dose and the person’s immune status can cause some variability, but 1–12 days (usually about 7) is the standard pattern.
