It’s highly contagious, so catching it early is key.
That thing we call the stomach flu? It’s actually not the flu at all. The real name for this kind of illness is “gastroenteritis.” Stomach bugs can be caused by a variety of different viruses that infect and inflames the lining of the intestines.
This stomach virus is often referred to as a flu because they can share a lot of similar symptoms, according to Preeti Parikh, MD, a pediatrician at The Mount Sinai Hospital and chief medical editor for HealthiNation.
“There are many types of viruses that can cause a stomach bug,” says Dr. Parikh, “but the two most common are norovirus and rotavirus.” There’s a rotavirus vaccination for infants to prevent this type of stomach virus, but there is not yet a vaccine for norovirus, which more commonly affects adults. (It’s also known as the cruise ship virus.)
Stomach viruses are highly contagious, and you can catch one in a few different ways, according to the National Institute of Diabetes and Digestive and Kidney Diseases:
Not washing your hands after touching a contaminated surface or object, including your sick baby’s diaper
Sharing food or drink with someone who has the virus
Eating contaminated foods, like oysters from contaminated waters (but this is not the same as food poisoning)
Swallowing droplets from an infected person’s sneezes or coughs
Classic signs of the stomach bug include:
Although quite less than pleasant, the stomach flu is usually not a serious threat for most people, and the body can typically overcome a stomach virus on its own within a couple days. The most common complication is dehydration due to loss of fluids in the bathroom. Here’s how to prevent dehydration with a stomach virus.
That said, you’ll want to rule other more serious issues, such as appendicitis. Greenish vomit, constant vomiting and diarrhea, severe stomach pain, and tenderness in the lower right side of your abdomen are clues that your appendix is inflamed and requires immediate medical attention.

00:00:00,000 --> 00:00:02,385
00:00:02,385 --> 00:00:05,780
So a lot of times we hear of
something called the stomach flu but
00:00:05,780 --> 00:00:07,620
I like to call it a stomach virus.
00:00:07,620 --> 00:00:12,020
Because there are many different
viruses that can cause a stomach virus.
00:00:12,020 --> 00:00:16,181
And a lot of people talk stomach flu
because the flu can actually cause
00:00:16,181 --> 00:00:17,410
00:00:17,410 --> 00:00:21,914
00:00:21,914 --> 00:00:27,143
A stomach virus is when and individual, or
child, or adult, gets a virus that affects
00:00:27,143 --> 00:00:32,180
their intestines and can cause a lot of
symptoms which can be really debilitating.
00:00:32,180 --> 00:00:35,810
There are many types of viruses
that can cause a stomach bug, but
00:00:35,810 --> 00:00:39,890
the two most common are norovirus and
00:00:39,890 --> 00:00:45,011
And you can get the virus by touching
someone who's infected with the virus.
00:00:45,011 --> 00:00:48,846
Or if you're changing a baby's diaper and
you've touched the diarrhea, and
00:00:48,846 --> 00:00:51,050
you don't wash your hands right away.
00:00:51,050 --> 00:00:52,820
Certain surfaces can still have it.
00:00:52,820 --> 00:00:58,610
You can also get it from food that someone
who has been infected has cooked and
00:00:58,610 --> 00:00:59,280
you've eaten it.
00:00:59,280 --> 00:01:02,190
So there's many different
ways that you can get it.
00:01:02,190 --> 00:01:05,200
With the stomach bug you can
experience stomach cramps.
00:01:05,200 --> 00:01:08,020
You can experience nauseousness,
00:01:08,020 --> 00:01:10,760
You may be getting fever and chills.
00:01:10,760 --> 00:01:13,680
So these are symptoms that if you're
experiencing you may be having
00:01:13,680 --> 00:01:15,240
the stomach bug.
00:01:15,240 --> 00:01:18,940
So how do you tell if the stomach
virus if just a stomach virus or
00:01:18,940 --> 00:01:21,180
you're actually having
something more serious?
00:01:21,180 --> 00:01:23,870
And those are the questions that I
get all the time from my patients.
00:01:23,870 --> 00:01:27,925
So things that I tell them to watch for is
that if the vomiting is turning greenish
00:01:27,925 --> 00:01:30,784
in color, that you're not
able to keep anything down.
00:01:30,784 --> 00:01:33,843
You're just constantly vomiting or
constantly having diarrhea and
00:01:33,843 --> 00:01:35,740
you're getting dehydrated.
00:01:35,740 --> 00:01:40,390
You're having such significant
stomach pain or abdominal cramps.
00:01:40,390 --> 00:01:44,194
And when you touch the right
lower side of your abdomen, and
00:01:44,194 --> 00:01:48,240
it's really very tender,
it could be a sign of appendicitis.
00:01:48,240 --> 00:01:52,834
So making sure you touch base with your
doctor to make sure it's not something
00:01:52,834 --> 00:01:54,190
00:01:54,190 --> 00:01:56,603
It's better to be safe than sorry.
00:01:56,603 --> 00:02:01,509
