Norovirus Infects The US

Norovirus Infects The US.
Norovirus, the monstrous stomach bug that's sickened countless sail ship passengers, also wreaks havoc on land. Each year, many children descend upon their doctor or an emergency room due to severe vomiting and diarrhea caused by norovirus, according to unheard of research from the US Centers for Disease Control and Prevention. The CDC announcement estimated the cost of those illnesses at more than $273 million annually. "The main point we found was that the healthiness care burden in children under 5 years old from norovirus was surprisingly great, causing nearly 1 million medical visits per year," said the study's create author, Daniel Payne, an epidemiologist with the CDC. "The secondly point was that, for the first time, norovirus salubrity care visits have exceeded those for rotavirus".

Rotavirus is a common gastrointestinal illness for which there is now a vaccine. It's mighty to note that the rate of norovirus hasn't been increasing in young children. The rationale norovirus is now responsible for more health care visits than rotavirus is that the incidence of rotavirus infection is dropping because the rotavirus vaccine is working well.

Results of the mull over are published in the March 21, 2013 affair of the New England Journal of Medicine. Norovirus is a viral illness that can affect anyone, according to the CDC. It commonly causes nausea, diarrhea, vomiting and gut cramps.

Most people pull through from a norovirus infection in a day or two, but the very young and the very old - as well as those with underlying medical conditions - have a greater peril of becoming dehydrated when they're sick with norovirus. The virus is very contagious. Payne said it takes as few as 18 norovirus particles to infect someone. By comparison, a flu virus may function between 100 and 1000 virus particles to cause infection.

Payne said ancestors who have been infected can also detain spreading the virus even after they feel better. Norovirus is difficult to determine definitively. The test that can confirm the virus is costly and time consuming so there have not been good information on how many children are affected by it each year.

To get a better idea of how prevalent this infection really is, the researchers tranquil samples from hospitals, emergency departments and outpatient clinics from children under 5 years antique who had acute gastrointestinal symptoms. The children were from three US counties: Monroe County, NY; Davidson County, TN; and Hamilton County, OH.
