Public Health England (PHE) recently issued a warning after finding a jump in norovirus cases during a routine surveillance. And in a more worrying development, the PHE reported increase in norovirus cases in educational settings, particularly in nursery and childcare facilities. According to Centers for Disease Control and Prevention (CDC), norovirus is a very contagious virus that causes vomiting and diarrhea. And infection with one type of norovirus may not protect you against other types, the health body further said. Though there is a possibility to develop immunity against certain types of norovirus, experts are not yet able to determine how long that immunity lasts.
