Crete: investigation continues into 93 gastroenteritis cases
Officials report a downward trend and negative results so far, with no identified pathogen or common source. Water samples are also being tested.
Ninety-three cases of gastroenteritis have been recorded in Crete, while an epidemiological investigation continues by Greece's National Public Health Organization (EODY), the regional authority and local authorities. ERT reported the figures on 8 October 2026, citing statements by EODY president Theodoros Vasilakopoulos and the Region of Crete's public-health director-general, Antonis Papadakis.
According to Papadakis, EODY formally notified the regional authority on Monday, 6 October, of 73 cases, with another 20 reported afterwards. He said the daily count showed a downward trend and described the situation as under control.
What the first tests have shown
The EODY president said the stool cultures completed so far were negative for bacteria, while the limited viral tests then available had also not produced a positive result. This means that no pathogen has been identified; it is not a final conclusion about the cause of the cases.
No common source of transmission or link to a large social event has emerged so far. Patients mainly experienced vomiting and, to a lesser extent, diarrhoea. According to the officials' statements, all have recovered and no severe risk was recorded.
Water is being tested — contamination has not been confirmed
Because of the recent flooding, investigators are examining possible damage or contamination in water-supply networks among the potential causes. Water samples from different locations are being sent to accredited laboratories, and the investigation also includes wastewater analysis.
There is, however, no confirmation at this stage that water is responsible. Any final conclusion will need to combine laboratory findings from patients, water and wastewater. The timing of the cases after the floods is a line of inquiry, not proof of causation.
What remains unresolved
Services are continuing to take patient histories and look for a possible link between the cases. The precise cause, whether there is a common source and whether a specific virus or other pathogen will ultimately be isolated all remain unresolved. A further assessment requires the completed laboratory results.
