As temperatures cool across Chattanooga and families spend more time indoors, respiratory illnesses tend to make their rounds. A scratchy throat or stuffy nose might seem like an ordinary cold at first, but sometimes those symptoms are the beginning of something more.
Influenza (the flu) and respiratory syncytial virus (RSV) can cause symptoms that overlap with the common cold. While many people recover at home, these illnesses can sometimes lead to serious complications, especially for young children, older adults and people with certain underlying health conditions. So, how can you tell when a cold might be something else? Knowing what to watch for can help you decide when rest at home is enough and when it’s time to get checked out at AFC Chattanooga Northshore.
How Can You Tell the Difference Between a Cold, the Flu and RSV?
Because these illnesses share many symptoms, it isn’t always possible to identify the cause based on how you feel alone. However, the way symptoms begin and how severe they become can offer some clues.
The Common Cold
Colds usually develop gradually and tend to cause milder symptoms. You might notice a runny or stuffy nose, sneezing, a sore throat or a mild cough. Some people experience fatigue or a low-grade fever, but significant body aches and intense exhaustion are less typical. Most colds improve within about a week to 10 days, although a cough or congestion can linger longer.
Influenza (The Flu)
The flu often comes on more suddenly than a cold. You might feel relatively fine one day and wake up the next feeling completely wiped out.
Common flu symptoms include:
- Fever or chills
- Muscle and body aches
- Headache
- Significant fatigue
- Cough and sore throat
- Runny or stuffy nose
Not everyone with the flu develops a fever, so the absence of one doesn’t necessarily rule it out. The flu can also lead to complications such as pneumonia, particularly in people at higher risk.
Respiratory Syncytial Virus (RSV)
RSV often resembles a cold in adults, with symptoms such as congestion, a runny nose, coughing, sneezing and fever. However, it can be more serious in infants, young children and older adults.
In babies, RSV may cause poor feeding, irritability, decreased activity or breathing difficulties. In some cases, it can lead to bronchiolitis, an inflammation of the small airways in the lungs, or pneumonia. Older adults and people with certain chronic medical conditions may also develop more severe respiratory symptoms.
What Warning Signs Should You Watch For?
A mild cough or stuffy nose doesn’t automatically mean you need medical attention. The important thing is to pay attention to how your symptoms progress and whether they interfere with your ability to breathe, drink fluids or carry out normal activities. Consider getting evaluated at AFC Chattanooga Northshore if you experience:
- A fever that persists or returns after improving
- Symptoms that are getting worse instead of better
- A cough that becomes increasingly severe
- Wheezing or new breathing discomfort
- Significant fatigue that makes everyday activities difficult
- Signs of dehydration, such as very little urination, dizziness or a dry mouth
- Symptoms that improve and then return more severely
For infants, watch for difficulty feeding, fewer wet diapers, unusual sleepiness or increased effort when breathing. These signs deserve prompt medical attention. Seek emergency care immediately for severe difficulty breathing, persistent chest pain or pressure, blue or gray lips or skin, new confusion, difficulty waking or other signs of a medical emergency. If a child is struggling to breathe, don’t wait for symptoms to improve on their own.
When Should You Get Tested for the Flu or RSV?
Testing may help determine what’s causing your symptoms, particularly when the results could affect treatment or precautions to protect others. Flu and COVID-19 symptoms can overlap, and some respiratory tests can help identify more than one virus. RSV testing may be recommended in certain situations, depending on a person’s age, symptoms and risk factors.
Timing can matter, too. Prescription antiviral medication for the flu works best when started early, generally within the first 48 hours of symptoms, although treatment may still be recommended later for people who are at higher risk or seriously ill. If you’re experiencing flu-like symptoms, contact a healthcare provider promptly rather than waiting until you feel worse to ask about treatment.
How Can You Help Prevent Respiratory Illnesses?
You can’t avoid every virus, but a few everyday habits can help lower your risk of getting sick or spreading illness to others.
- Wash your hands regularly. Use soap and water, especially before eating and after coughing, sneezing or blowing your nose.
- Cover coughs and sneezes. Use a tissue or your elbow, and wash your hands afterward.
- Improve indoor ventilation. When practical, bring in fresh air or use appropriate air filtration.
- Stay home when you’re sick. Give yourself time to recover and reduce the chance of passing an illness to coworkers, classmates or family members.
- Stay up to date on recommended vaccines. Seasonal flu and COVID-19 vaccines can help protect against severe illness. RSV immunization is also recommended for certain groups, including eligible infants and older adults, based on current guidance.
If you live with someone who is at higher risk of complications, taking these precautions is especially important.
