A slight tickle in your throat, body aches, and a sudden fever could be some of the first signs that you’re coming down with the flu.
The influenza virus (or flu for short) affects up to 20 percent of the U.S. population each year. It’s crucial that you recognize the symptoms early so you can start taking care of yourself.
It’s especially critical for young children, older adults, pregnant women, or people with conditions that affect their respiratory or immune systems to seek medical attention quickly.
These tips will not only help you feel better faster, but also help prevent the spread of this highly contagious virus to other people in your community.
It’s easy to mistake the flu for a minor cold at first. While the flu shares many of the symptoms of the common cold, symptoms of the flu are typically more severe and come on quicker.
Early signs of the flu include:
- sudden fever (usually above 100°F [38°C])
- scratchy or sore throat
- muscle or body aches
- runny nose
Keep in mind that a fever is common in the early stages of the flu, but not everyone with the flu will have a fever.
If you notice that you’re experiencing signs of the flu, follow these tips:
- Wash your hands frequently
to prevent the spread of the virus. Aim for about 20 seconds of scrubbing
with soap and water before rinsing.
- Cover coughs and sneezes with your arm
instead of your hands, or direct them into a disposable tissue. The flu is
highly contagious and easily spreads through the air if you cough or
- Eat healthy to boost your immune
system. Though you might lose your appetite when you’re sick, eating small
meals rich in fruits and vegetables will help give your body the strength
it needs to fight off the virus.
- Drink lots of fluids, especially water, tea,
and low-sugar electrolyte drinks. Avoid alcohol and caffeine.
- Purchase the essentials, such as tissues,
over-the-counter pain relievers, decongestants, cough suppressants, your
favorite tea, and fresh fruits and vegetables to snack on while you’re at
home. If you’re already feeling ill, though, it might be a good idea to
ask a friend or loved one to do your shopping for you.
- Alert your workplace. It can be hard to take
off from work, but your boss will appreciate it if you stay home to avoid
getting your co-workers sick.
- Stay home and rest. Ultimately, the best treatment for the flu is to get enough rest.
- Be diligent about hygiene. Wash your hands frequently. You can keep antibacterial wipes on hand to combat the spread of germs.
At the first signs of the flu, avoid doing any of the following:
- Don’t go to work or school. You’re
contagious a day or two before your symptoms begin and remain contagious
for up to five to seven days after you started feeling sick.
- Don’t shake people’s hands or hug them. You
don’t want to play a role in spreading the virus, so avoid making physical
contact with others or sharing food and drinks.
- Don’t push yourself. The flu is a progressive
illness, meaning your symptoms will worsen before they get better.
Depriving your body of rest in the first couple days after symptoms start
can end up lengthening the time it takes for you to recover.
- Avoid processed foods and sugar,
as these foods won’t give you many nutrients.
- Try not to skip meals. It’s fine to eat a little
less when you have the flu, but your body still needs nutrition and energy
to fight off the virus. Soup, yogurt, fruits, vegetables, oatmeal, and
broth are all great options.
- Don’t venture into crowded places since
the flu is highly contagious.
- Be cautious with unproven herbal remedies. If
you want to try an herbal remedy, be careful. Herbs and supplements aren’t
scrutinized by the FDA for quality, packaging, and safety. Make sure to
buy them from a reputable source or ask your doctor for a recommendation.
- Don’t smoke. The flu is a respiratory
illness, and smoking will irritate your lungs and make your symptoms worse.
You might think it’s safe to just stay home and rest if you’ve come down with the flu. But it’s a good idea to see a doctor if you fall into any of the categories below.
You’re considered high risk
Some people are at a higher risk of experiencing dangerous flu-related complications, like pneumonia or bronchitis. According to guidelines from the Infectious Diseases Society of America (IDSA), high-risk individuals include:
- people ages 65 years and older
- children 18 years of age and younger who are taking aspirin-based or salicylate-based medications
- children younger than 5 years of age, especially those under 2
- people who live with chronic medical conditions (such
as asthma, diabetes, or heart disease)
- people with a compromised immune system
- women who are pregnant or up to two weeks postpartum
- residents of nursing homes and other long-term care facilities
- Native Americans (American Indians and Alaska Natives)
If you fit into one of these categories, you should see a doctor at the earliest signs of the flu. A doctor may decide to prescribe an antiviral medication. These medications work best when they’re taken within the first 48 hours after symptoms start.
You’re experiencing severe symptoms
For adults, signs of an emergency include:
- difficulty breathing or shortness of breath
- chest pain
- severe or persistent vomiting
- sudden dizziness
For infants and children, emergency flu symptoms include:
- trouble breathing
- blueish skin
- fever that accompanies a rash
- inability to eat or drink
- no tears when crying
Flu-like symptoms get better, but then get worse
Most people recover from the flu within one to two weeks. Others will start to get better and then find that their condition rapidly deteriorates and their fever spikes again.
If this happens, it could mean that you have a flu complication like pneumonia, an ear infection, or bronchitis. You should see a doctor right away.
While you may be able to carry on working or going to the gym with a cold, the flu may make you feel too ill to follow your usual routine. It can be difficult to miss work or school, but if you’re starting to notice early signs of the flu, do yourself and everyone else a favor and stay home, especially if you have a fever. If you go out while sick, you could be putting other people at great risk for serious illness and you’ll only be making your recovery more difficult.
