In simple words: Calicivirus enteritis is a stomach bug caused by a virus called calicivirus. It can cause diarrhea, nausea, vomiting, stomach cramps, muscle aches, tiredness, and headaches. You can get it from contaminated food or water, or from contact with someone who is infected. Treatment usually involves drinking plenty of fluids to avoid dehydration.

Calicivirus enteritis is a viral infection of the intestines caused by the calicivirus, typically ingested through contaminated food or water or spread through person-to-person contact.Symptoms include diarrhea, nausea, vomiting, abdominal cramps, muscle pain, fatigue, and headache. Diagnosis is based on symptoms, history, physical examination, and laboratory tests of blood, feces, and vomit. Treatment focuses on rehydration with oral or intravenous fluids, as antibiotics are ineffective against viruses.

Example 1: A patient presents with vomiting, diarrhea, and abdominal cramps after eating at a seafood restaurant. Lab tests confirm Calicivirus., A child experiences diarrhea and vomiting after attending a daycare center.The symptoms align with Calicivirus enteritis, and other children at the daycare have similar symptoms, suggesting an outbreak., An elderly patient in a nursing home develops severe dehydration from persistent diarrhea. Testing reveals Calicivirus as the cause.

Documentation should include signs and symptoms, history of potential exposure (e.g., contaminated food or contact with infected individuals), physical examination findings, and laboratory results confirming the diagnosis. Details of rehydration therapy provided should also be documented.
