The Gironde prefecture temporarily banned, Wednesday December 27, fishing, harvesting and marketing activities for all shellfish from the Arcachon basin. Insights into the 19/20 set by Soizick le Guyader, virologist at Ifremer.
How did norovirus appear, and what does it mean? “Noroviruses are gastroenteritis viruses, so they are present in the sick population, who will excrete it in the stools, which will end up in wastewater. When there is heavy rain or a problem with the wastewater network, these noroviruses can be released into the environment and be concentrated in oysters.“, indicates Soizick le Guyader, virologist at Ifremer.
Pay attention to the transmission
Analyzes were carried out by a laboratory approved by the Ministry of Food. “Indeed, the oysters were positive for norovirus, so there was definitely a presence of this virus in the oysters.“, relays Soizick le Guyader. The symptoms are those of acute gastroenteritis. No serious cases have been reported to date, but the virus can be transmitted. “If there is a sick person in the family, then (…) we can transmit this virus to other people, possibly to more vulnerable people, for whom this virus could be more dangerous.warns the virologist.
