But many flu-like symptoms can overlap with other conditions like the common cold, allergies, and COVID-19. Here's some helpful tips to determine if you have the flu, or something else.
Symptoms of the flu
The most common symptoms of the flu include:
- Body aches
Less common symptoms of the flu include:
- Stuffy nose
- Sore throat
It's important to note that symptoms can vary slightly from person to person.
But if it's the flu, everyone experiences those hallmark symptoms "whether you're 2 or 200."
How do I know if I have the flu?
Your symptoms are a good start to figuring out if you have the flu or something else. Here's a chart comparing the flu with other common illnesses, including the novel coronavirus:
However, the only way to know for sure whether it's the flu is a nasal or throat swab test at the doctor's office.
If you've recently been vaccinated against the flu and are experiencing flu-like symptoms, it's still possible that you have it. Because you can still get the flu after a flu shot, though your chances are lower.
Other times, Landon says that people think they have the flu, but they're sick with something else entirely — a fungal infection, bacterial pneumonia, or even a heart attack.
And if you've got a 24-hour case of vomiting or diarrhea: "That's not the flu," she says. "That's probably norovirus or some other winter virus." If that's the case, check out our article on what you can eat to help relieve those symptoms.
People at high risk from the flu
The flu can infect anybody but there are certain populations at higher risk of developing complications from the infection. These demographics include:
- Seniors over the age of 65
- People with diabetes
- People with heart disease or hypertension
- Anyone with a chronic medical condition that leaves them immunocompromised
- Pregnant women
Pregnant women are considered a high-risk flu group, which is why they should get a flu shot. Flu in the third trimester increases the risk of early labor and makes women more likely to spread the virus to the newborn baby.
"That can be avoided by getting the flu shot, washing your hands, and not being around other people who are sick," Landon says. And don't worry about confusing flu symptoms with general pregnancy discomfort.
"Pregnant misery is one thing. Early on in pregnancy, you may be tired, have nausea, not feel great," Landon says. "You should not have chills, sweats, or fever." If you get the flu or fever when you're pregnant, see your doctor as soon as possible. Physicians can prescribe antiviral medications, which cut down on symptoms, help prevent complications, and take the edge off.
What to do if you feel the flu coming on
If you think you have the flu stay home and avoid contact with others as the flu is highly contagious.
Most people, who are otherwise healthy, do not need to seek medical care for their symptoms.
Instead, take it easy, get rest, reschedule plans, and call in sick from work or school. You should start to feel better in one to two weeks.
When to see a doctor
If you are around high-risk individuals like newborns or grandparents, it may be beneficial to get tested. Since the flu is highly contagious, knowing whether or not you have it can help prevent its spread
Finally, testing is especially important for individuals who may be unable to communicate their symptoms effectively like children or those with dementia.
