Looks like it’s virus season. Another highly contagious virus, norovirus, also known as the vomiting bug, has joined such a sparsely populated clan. Public Health England (PHE) said that norovirus cases have been increasing recently across England.
Here’s everything you need about the virus:
What is norovirus?
According to the Centers for Disease Control and Prevention (CDC), norovirus is a highly contagious virus that causes more than half of all foodborne illnesses in the United States.
While norovirus is also known as the stomach flu, it is not actually related to the seasonal flu, which is caused by the influenza virus, and is not related to the virus that causes COVID-19. Other names for norovirus include “food poisoning” and “stomach bug,” notes the CDC.
What are its symptoms?
Symptoms of acute gastroenteritis from norovirus usually develop 12 to 48 hours after catching the virus and last about one to three days. Some of the most common symptoms include diarrhea, abdominal pain, nausea and vomiting, fever, headache and body aches.
It is also possible to have norovirus but not show any signs of illness, notes the Mayo Clinic.
How dangerous is this?
Norovirus is found in the feces and vomit of people infected with the virus. People accidentally get norovirus from small amounts of these stools or vomit, which can be found on unwashed food, contaminated water, or contaminated surfaces.
People with infection can release billions of norovirus particles; According to the CDC, it only takes small amounts of those particles to make someone sick.
How is it broadcast?
Eating food or drinking liquids that have been contaminated with norovirus (for example, food grown in contaminated water). Touching an object or surface contaminated with norovirus, then touching your mouth. Being in direct contact – such as sharing food or utensils – with a person who has norovirus. Drinking contaminated water from a well or from a pool that has not been properly cleaned.
How is norovirus diagnosed?
A doctor can usually diagnose norovirus based on a person’s symptoms. Norovirus can also be detected in a stool sample. If you have an underlying health problem or a weakened immune system, your doctor may order a stool test.
Is it curable?
Most people recover from norovirus without needing any treatment, but older adults, young children, and people with underlying medical conditions may be more vulnerable to dehydration, and may therefore need medical treatment or even a hospital stay. may be required.
How long does it take to recover?
Norovirus usually lasts one to three days.
Although symptoms usually only last a few days, people are contagious for much longer. Some people may continue to shed the virus in their stool for weeks or months after recovering from the infection, if you have underlying conditions.
Because there are many different types of norovirus, you can get sick more than once. Some people may develop immunity to certain types of norovirus, but it is not clear how long their immunity lasts.
