TL;DR: In this paper, the authors reported a total of 22 waterborne-disease outbreaks associated with drinking water and recreational lake water, which caused an estimated total of 2,567 persons to become ill. No deaths were reported.

TL;DR: The number of recreational water-associated outbreaks has increased significantly during this period and could reflect improved surveillance and reporting at the local and state level, a true increase in the number of WBDOs, or a combination of these factors.

TL;DR: This surveillance system is the primary source of data concerning the scope and effects of waterborne diseases on persons in the United States and reports on outbreaks occurring during January 1999-December 2000 and previously unreported outbreaks occurring in 1995 and 1997.

TL;DR: This surveillance summary probably underestimate the true incidence of waterborne disease associated with drinking water because not all WBDOs are recognized, investigated, and reported to CDC or EPA.

TL;DR: Genetic variation at the two loci suggests that most cases of PCP do not result from infections acquired early in life, that infections are actively acquired from a relatively common source (humans or the environment), and that humans, while not necessarily involved in direct infection of other humans, are nevertheless important in the transmission cycle of P. carinii f.
