When you or a loved one starts to cough or have a runny nose, it’s normal to worry – especially in the fall and winter when everyone seems to be getting sick. Colds, the flu and RSV are especially widespread during the colder months. Though these illnesses have similar symptoms, there are a few telltale signs that can help you tell them apart. By understanding each condition, you can learn how to protect yourself from getting sick, how to treat the symptoms and know when you need professional medical care.
What is a Cold?
Rhinovirus, or the common cold, can be spread and caught year-round, but it’s particularly pervasive during fall and winter. Colds are generally mild and come on gradually.
Symptoms include:
- Runny nose
- Sore throat
- Cough
- Sneezing
- Watery eyes
- Little to no fever
How is it Treated?
Most colds improve on their own within seven to 10 days. They can be managed with rest, hydration, and over-the-counter medications like Tylenol and Ibuprofen. Sometimes coughing and congestion can last longer than 10 days. Call your doctor if you’re experiencing more serious breathing complications.
What is the Flu?
The flu is a highly contagious respiratory illness caused by the influenza virus. It infects tissues in the nose and throat, and sometimes the lungs. It causes mild to severe illness, and typically flu symptoms appear suddenly, within one to four days.
Common symptoms of the flu include:
- Runny nose
- Fatigue
- Cough
- Headache
- Body aches
- Fever or chills
Some people may experience more severe flu symptoms. If you experience any of the following symptoms, seek immediate medical attention:
- Difficulty breathing
- Persistent chest or stomach pain
- Confusion or dizziness
- Severe weakness or muscle pain
- Inability to urinate
- Seizures
How is it Treated?
The flu can be treated with rest, hydration and antiviral medications prescribed by a doctor. If you get sick with the flu, you should:
- Stay home until you feel better
- Drink plenty of fluids, such as water and soup
- Avoid things that could worsen your symptoms, such as alcohol or tobacco
- Take ibuprofen or Tylenol to help reduce your fever
One of the best ways to protect yourself and others against the flu is by getting a flu shot. Many pharmacies and clinics offer the flu shot for free each year, and the vaccine protects against multiple strains of the flu – not just one.
Yearly flu vaccination is a simple, science‑backed step you can take toward staying healthy and preventing the spread of illness, especially to those who are most vulnerable.
What is RSV?
Respiratory syncytial virus (RSV) is a common respiratory virus that infects the nose, throat, lungs and respiratory tract. It is contagious and easily spread through close contact with someone who has RSV, coughing and sneezing, and contaminated surfaces.
Common symptoms of RSV include:
- Runny nose or congestion
- Decreased appetite
- Cough
- Sneezing
- Wheezing
- Fever
Symptoms of RSV in babies and children may present differently. Go to an emergency room if your child has severe RSV symptoms, which include:
- Shortness of breath, wheezing or noisy breathing
- Bluish or grayish skin, nails and lips
- Nostrils flaring when breathing
- Short, shallow or fast breathing
- Pauses in breathing
- Caving in of the chest with expansion of the belly when breathing
How is it Treated?
Though there is no specific treatment for RSV, treating the symptoms may help you feel better sooner. RSV symptoms can be treated in the following ways:
- Taking medications, such as over-the-counter pain relievers or fever reducers
- Drinking fluids and staying hydrated
Talk to your doctor if your symptoms worsen.
Staying Healthy
While colds, the flu and RSV share many of the same symptoms, understanding the differences can help you make informed decisions about your health and know when it’s time to seek medical care. Practicing good hygiene, staying home when you’re sick, keeping up with recommended vaccinations and taking steps to support your immune system can help reduce your risk of illness.
If you’re unsure about your symptoms or they become severe, don’t hesitate to contact your healthcare provider. With the right precautions and prompt care when needed, you can help protect yourself, your family and your community throughout cold and flu season.
