It has been reported that some patients have been misdiagnosed with Sapovirus, when in fact the correct diagnosis in their specific case was Norovirus.
Norovirus is a highly contagious viral infection that causes gastroenteritis (severe sudden vomiting and diarrhea) that occurs 12 to 48 hours after exposure. These viruses typically spread in places like cruise ships, child care centres and nursing homes. Symptoms include nausea, vomiting, stomach pain or cramps, watery loose stool, fever and muscle pain. Norovirus can be misdiagnosed as rotavirus infections, inflammatory bowel disease or Cron’s disease.
