In Corsica, more precisely on the long-distance hiking trail 20, at least 236 people have suffered from gastric problems due to the circulation of the norovirus, responsible for gastroenteritis.
- At least 236 hikers have developed gastroenteritis on the long-distance hiking trail 20 in Corsica.
- “No serious cases, 7 short-term hospitalizations were recorded,” according to the island’s Regional Health Agency.
- According to initial investigations, the outbreak is believed to be mainly caused by norovirus.
On July 26, the Regional Health Agency (ARS) of Corsica has warned of the appearance of several cases of gastroenteritis among hikers on the GR20, a hiking route that crosses Corsica from north to south via the mountain range. “The epidemic probably started at the end of June, with a peak observed on July 12.”
Nausea, vomiting, diarrhea: 236 cases of gastroenteritis on the GR20
To determine the number of people affected and the origins of this situation “unusual”the ARS Corsica, in collaboration with Public Health France and the Corsican Regional Natural Park, conducted investigations. Verdict: at least 236 patients were recorded between July 1 and 15. “No serious cases, 7 short-term hospitalizations were recorded.” Reported symptoms include mainly diarrhea, abdominal pain, fatigue and nausea and vomiting.
According to the first results of the investigations, the norovirus seems to be at the origin of this epidemic. The latter causes acute gastroenteritis lasting two to three days on average and without complications. In children and the elderly, the duration of symptoms can be longer. As a reminder, this virus is easily transmitted from person to person, for example by sharing food with a sick adult, by touching contaminated surfaces or objects and then putting your fingers in your mouth, by consuming contaminated products. However, the health authorities specify that “other pathogens, such as bacteria, may also be linked to this episode.”
Hiking: what to do to avoid getting sick
“Although the epidemic peak has passed, it is crucial to remain vigilant,” reports ARS Corsica. Thus, it reminds that during hikes, it is advisable to wash your hands regularly with soap or a hydroalcoholic solution, more precisely before and after going to the toilet, before preparing a meal and before eating. The agency also advises treating or filtering water before consuming it, as it can carry pathogens. “Use portable filters, purification tablets or boil water before drinking.” Finally, in the event of gastric problems, you should avoid preparing meals for other hikers until 48 hours after the symptoms have ended.
