Monitor norovirus for 14 days in elderly patients

A recent study has suggested that elderly patients infected with norovirus should be monitored for infectivity for at least 14 days after the onset of symptoms.

The study looked at the period of infectivity in norovirus-infected individuals, in order to prevent the spread of norovirus in care homes.

Researchers monitored 13 elderly patients aged 60-98 years with norovirus gastroenteritis and found that the average period of norovirus excretion was 14 days.

The authors suggest that careful attention should be taken for at least 14 days after the onset of symptoms and that the measurement of viral load in stools around 16 days after onset might be a useful method for following the course of viral shedding for each patient infected with norovirus.
