The U.S. Centers for Disease Control and Prevention (CDC) reports that the new norovirus strain, called GII.4 Sydney was accounted for 58% of cases of the infection in December. It was first identified in March 2012 in Australia and called as the Sydney strain. The new norovirus strain once known as Norwalk virus has also struck in France and New Zealand. The season of norovirus runs from November through March and cases typically peak in January.



Norovirus Strain comes in five forms. "It's a little like flu," Jan Vinje, a CDC epidemiologist told the Washington Post. This infectious disease often called as "food poisoning" or "stomach flu”, but the truth is that this disease is not related to the stomach flu (influenza). It is true that food poisoning can be caused by noroviruses. Normally disease last no more than a couple of days for healthy people but it will become serious in young children, the elderly, and people with other health conditions. People can get norovirus illness more than once during your life.

The Characteristics of the New Norovirus Strain

New norovirus strain often called the ‘winter vomiting bug’ because it involves severe vomiting and diarrhea. It caused 21 million cases of illness in America.

What happens in each year in the U.S?

70,000 hospitalizations, causes about 20 million gastroenteritis cases, 800 deaths

Symptoms

This infectious disease often confused with the stomach flu but as I said earlier it has no relation with the stomach flu.

It involves stomach cramping that causes inflammation of tissues that leads to pain. Reports of patients show that they suffered unimaginable pain in the abdomen.

Vomiting leads to dehydration and loss of electrolytes, a decrease in urination and a dry mouth and throat.

Less common symptoms may include low-grade fever, chills, headache, muscle aches, and general sense of fatigue.

Transmission

Spreads so quickly and the math shows that 51% of the cases in the U.S. were caused by person-to-person transmission and 20% resulted from contaminated food.

Norovirus infections are difficult to contain because millions of particles spread to environment and one or two particle is enough to make the next person sick. I think you got the idea.

Treatments

There are no treatments for norovirus till now. But scientists are trying to invent a vaccine called LigoCyte Pharmaceuticals.

Prevention

Keep a bunch of trash bags which will become handy because of vomiting.

Activated charcoal capsules can give a momentary relief.

Drink lots of Gatoraid.

Soup, bread and rice provide nutrition and fluid.

Don’t share towels and flannels

Stay at home to avoid person-to-person transmission.


The CDC recommends the following:

The main suggestions which is very simple by CDC is to wash your hands carefully. The hands should not be washed with just water. The hand must be washed with soap. If the soap is disinfectant, then it is more good.

The main thing to consider when washing hand is to clean the hand after using the restroom. Your hand will be dirt after the visit to bathroom.

Mothers also should wash their hands before changing diapers of children.

Mothers and others should also should not forget to wash hands with soap and water before handling food.

Do not prepare food while infected.

Carefully wash produce and seafood before cooking and consuming them.

Immediately clean any infected or contaminated surfaces and wash laundry thoroughly.

Try to avoid leafy greens (such as lettuce), fresh fruits, and shellfish (such as oysters) because the chance of getting the disease is too high for these common food items. However, any food item that is served raw or handled after being cooked can become contaminated with noroviruses.
