Japanese doctors are trying to determine the exact source behind the outbreak at the hospital, which began last month. The two fatalities were a 76-year-old woman and a 82-year-old man, according to the news agency.
Common symptoms of the norovirus include diarrhea and vomiting. Most people begin recovery just days after first showing signs of the illness. Doctors say dehydration caused by the virus puts the young and the elderly at greater risk due to their weaker immune systems.
Kyodo reported The National Institute of Infectious Diseases as saying 2012 has shown some of the highest infection rates on record for the virus, according to their data.
