Norovirus – Russia

November 23, 2021 – Approximately 46 people were reported to have been diagnosed with food poisoning, likely gastroenteritis (norovirus), in Tatarsk, Novosibirsk region, Russia. All cases report that they purchased food from a place called "Sushi House". It is suspected that the outbreak began on Friday, November 19, 2021. A family claimed that their children had fallen ill from the consumption of food ordered from that restaurant on Friday, November 19, 2021 ( three-year-old boy, nine-year-old girl, 19-year-old girl). They are among the 46 cases.

All cases have sought immediate medical care in a hospital in Tatarsk. Common symptoms reported by some of the cases include severe pain, and vomiting. Other symptoms can include diarrhea, nausea and fever.

Officials mention that current investigation is being carried. This is especially due to claims that the outbreak may be related to rotavirus and not gastroenteritis (norovirus). But based on the timing and origin of the outbreak, officials of the source still suspect that it is a case of food poisoning from the sushi restaurant. A conclusion has yet to be determined since this case is still under investigation.

Norovirus, sometimes referred to as the winter vomiting bug, is the most common cause of gastroenteritis.

Infection is characterized by non-bloody diarrhea, vomiting, and stomach pain. Fever or headaches may also occur. Symptoms usually develop 12 to 48 hours after being exposed, and recovery typically occurs within 1 to 3 days.

This may be through contaminated food or water or person-to-person contact. Risk factors include unsanitary food preparation and sharing close quarters.
