How long does the norovirus remain active on surfaces? When to see a doctor. As human HBGAs are associated with increased susceptibility to several pathogens such as HIV, rhinovirus, Haemophilus influenzae , Neisseria meningitidis , and urinary tract infections, it can be speculated that both pathogens and the host are under selection pressure resulting in genetic variation in both the circulating pathogens as well as the human population.
This genetic variation may include mutations in the cell and virus receptor mutations. In support of this notion is that genetic and phenotypic diversity of HBGAs have been found to be higher in sub-Saharan African populations compared to many other regions. However, it remains to be shown that secretor-dependent noroviruses are using district cellular receptors in vivo. An interesting study would be to investigate the occurrence of norovirus genotypes in regions with very high proportion of non-secretors.
Our interest in the field arose after scientific reports and our own clinical observations established that certain individuals repeatedly remain resistant to clinical symptoms following norovirus infections. Some people may even develop an infection after eating steamed shellfish. Noroviruses can also survive in up to 10 parts per million of chlorine , levels that are much higher than those available in current public water systems.
Despite these survival features, experts say that relatively simple personal and food hygiene measures can significantly reduce the foodborne transmission of noroviruses. Hospitals and other healthcare facilities also have a role to play in preventing transmission. They should focus on methods to limit the spread of the virus, such as isolating people with an infection.
In the vast majority of cases, a norovirus infection resolves itself within a few days and has no complications. Some people are unable to drink enough liquids to replace those that they lose through vomiting or diarrhea. They may become dehydrated and require special medical attention. Young children, older adults, and individuals of any age who need a caregiver are especially vulnerable. Learn more about managing dehydration here.
Eating contaminated food can lead to diarrhea, nausea, vomiting, and abdominal pain. It can also cause inflammation and develop into stomach flu. Rotavirus Gastroenteritis is a virus that infects the bowels and is most commonly found in unvaccinated children.
It can cause severe, fatal…. Diarrhea, which refers to unusually loose or watery stools, is a common problem with many potential causes. Several treatments can help. But in some people — especially children, older adults and people with compromised immune systems — norovirus infection can cause dehydration. Norovirus infection can cause severe dehydration, malnutrition and even death, especially in people who are older or immunocompromised, or in women who are pregnant. Children who are dehydrated might cry with few or no tears.
They might be unusually sleepy or fussy. Norovirus infection is highly contagious, and anyone can become infected more than once. To help prevent its spread:. Mayo Clinic does not endorse companies or products.
