What are the symptoms of stomach flu or gastroenteritis vs. COVID-19 symptoms?

For starters, it’s important to understand that gastroenteritis isn't actually a type of flu, even if it's colloquially known as the stomach flu. According to MedlinePlus, a resource from the US National Library of Medicine, gastroenteritis occurs when the lining of your intestines becomes inflamed. This can be the result of a virus, parasites, or bacteria, per MedlinePlus.

COVID-19, on the other hand, is an infectious diseases caused by a newly-discovered coronavirus, known as SARS-CoV-2. For the most part, according to the World Health Organization (WHO), those who get COVID-19 will experience a mild to moderate respiratory illness, and will often recover without medical treatment. But others—people over the age of 65 or those with other underlying conditions—are more likely to develop serious illness from the virus.

Another difference : COVID - 19 is more likely than the flu to cause a loss of taste or smell. But not everyone experiences that symptom, so it’ s not a reliable way to tell the viruses apart. That leaves testing, which will become more important as flu season ramps up this fall in the Northern Hemisphere.

It's usually spread through infected respiratory droplets (like those that come from sneezes or coughs), which is why mask wearing is essential right now. And if the symptoms of the stomach flu look familiar, it could be because many of them are also signs of COVID-19, the known symptoms of which are:

  • Cough
  • Chills or fever
  • Difficulty breathing or shortness or breath
  • Body or muscle aches
  • Fatigue
  • Loss of smell or taste
  • Headache
  • Runny nose or congestion
  • Sore throat
  • Vomiting
  • Nausea
  • Diarrhea

How do you tell the difference between COVID-19 and the stomach flu?

So, how do you know which one you’re dealing with if you’re experiencing, for instance, a fever, vomiting, and diarrhea? Unfortunately, the answer isn’t clear cut, Cory Fisher, DO, who specializes in family medicine at Cleveland Clinic, tells Health. Among things to watch for are those upper respiratory symptoms and loss of taste and smell, since those differentiate gastroenteritis from COVID-19, Dr. Fisher says. “There are a lot of overlapping symptoms, although COVID tends to have more upper respiratory symptoms, cough, and a hallmark characteristic of loss of taste or smell,” he explains.

Another hint that you’re dealing with the coronavirus rather than the stomach flu is chest pains, Tania Elliott, MD, who specializes in infectious diseases at NYU Langone, tells Health. “There are some symptoms more specific to COVID-19, like loss of taste and smell, cough, or chest pains,” Dr. Elliott explains, adding, “Patients do not generally get these symptoms with a stomach flu.”

If you’re worried you have COVID-19, you should also keep in mind the infection rate in your town or community. If the infection rate is high, or you've come into contact with someone with COVID-19, you might not want to write off your symptoms as gastroenteritis right away. “If a patient has had any known exposure to COVID-19, these symptoms are much more concerning. In the end, it can be very difficult to tell clinically what the infectious agent is, and the one best way to know the difference is to get a coronavirus test,” Dr. Elliott says.

Regardless, the first step in addressing either your stomach flu or COVID-19 symptoms is probably putting in a call to your primary care doctor, Dr. Fisher says. (Unless, of course, you’re experiencing life-threatening symptoms such as difficulty breathing, in which case you should head to your local emergency room.) “I recommend calling your doctor and scheduling a telehealth visit so they can direct you to next steps, [including] how and where to get tested,” Dr. Fisher says. Overall, a telehealth visit can protect you from COVID-19 if you don't have it, and protect others from whatever's ailing you. “The emergency department and other high-level care locations should be reserved for those with severe symptoms, like shortness of breath or chest pain," Dr. Elliot says.

  What Is the Incubation Period of the Flu—And When Are You Most Contagious? You may be able to pass on the virus, even if you don't feel sick yet.It's known as the flu's incubation period, and "it's a big reason why the flu is so easily spread," Kathryn Boling, MD, a primary care physician at Baltimore's Mercy Medical Center, tells Health. But while you've likely heard all about symptoms of the flu (fever, cough, fatigue, etc.), best prevention tactics (the flu shot), and even any possible remedies (Tamiflu), you might be a little less sure about what the incubation period of the flu is, what that means, and if there's any way to know if you're in it. Here's what experts want you to know.

From there, your doctor can make their best guess on which virus you may be suffering from, and offer advice on how to start feeling better. But note: Neither COVID-19 or gastroenteritis have any specific treatments right now, unless you're seriously ill and need medical attention. If you're well enough to stay home and care for yourself there, your best bet for either illness will be symptom management, and if you're suffering from diarrhea or vomiting, the best route there is, again, to remain as hydrated as possible.
