Impact of heavy precipitation events on pathogen occurrence in estuarine areas of the Puzi River in Taiwan.

Pathogen populations in estuarine areas are dynamic, as they are subject to multiple natural and anthropogenic challenges. Heavy rainfall events bring instability to the aquatic environment in estuaries, causing changes in pathogen populations and increased environmental sanitation and public health...
