Norovirus continues to ravage Japan after four elderly patients died in an outbreak at a hospital in the western Japanese city of Kyoto.

Earlier, at least 77 contracted Norovirus after consuming bentos from a store, and over 1,000 schoolchildren were stricken after consuming bread that was probably contaminated by food workers.

The four victims at the hospital were in their 80s and 90s and were among 101 patients and staff members who have exhibited the virus-caused gastroenteritis symptoms of vomiting and diarrhea over the past five weeks at the hospital in Fushimi Ward of the city.
