These figures suggest that (a) even when ingesting large amounts of the parasite, the chance of contracting giardiasis is less than 1 in 2, and (b) if you are one of the unlucky ones to contract it, the chance of having symptoms is less than 1 in 4.
Or because the incubation period is usually from one to four weeks, even if it is giardiasis the uncertainty range indicates that the culprits could have been ingested anytime during a full three weeks worth of meals and beverages.
Specifically, the attack rate was far beyond that usually seen with water-contracted giardiasis, no cysts were identified in the suspect water, there was no association between water consumption rates and the likelihood of the disease, and the authors categorically discounted food-borne or fecal-oral spread, stating that it had never been reported (correct at the time).
