Hypothesis
What are the health risks for divers exposed to waterborne pathogens?
Conclusion
Divers face significant infection risks when diving in fecal-contaminated waters, especially in certain conditions.
Supporting Evidence
- The study is the first to estimate how much water divers swallow.
- Infection risks for C. jejuni were generally higher than for enteroviruses.
- The greatest per-dive mean risk of infection for occupational divers was 2.8% in coastal waters near sewage discharge.
- Sport divers had a 1.5% per-dive risk and a 25% per-year risk in freshwater recreational waters.
- Wearing full face masks reduced the risk of infection for sport divers.
Takeaway
Diving in dirty water can make you sick, so it's important for divers to wear special masks and know about water quality.
Methodology
Researchers used questionnaires to gather data from divers about their diving habits and health complaints.
Participant Demographics
Occupational and sport divers from various water environments.
