Respiratory infections are common illnesses that affect the nose, throat, airways, and lungs. They can occur at any time of the year, but some infections become more common during the fall and winter months. Understanding the signs and symptoms of respiratory infections can help you recognize when you may be getting sick and when it is important to seek medical attention.
What Are Respiratory Infections?
Respiratory infections are caused by viruses or bacteria that enter the respiratory system. Some infections are mild and improve on their own, while others can become serious and require medical treatment.
Common respiratory infections include:
- The common cold: Usually causes a runny or stuffy nose, sneezing, sore throat, and coughing.
- Influenza (flu): Often causes fever, chills, body aches, headache, fatigue, and cough.
- COVID-19: May cause fever, cough, sore throat, congestion, fatigue, and changes in taste or smell.
- Bronchitis: Involves inflammation of the airways and commonly causes a persistent cough, sometimes with mucus.
- Pneumonia: An infection of the lungs that may cause fever, cough, chest discomfort, shortness of breath, and fatigue.
What Are the Common Signs and Symptoms?
Respiratory infections can cause different symptoms depending on the type of infection and the person’s overall health. Common symptoms include:
- Coughing, with or without mucus
- Runny or stuffy nose
- Sneezing
- Sore or scratchy throat
- Fever and chills
- Headache and body aches
- Tiredness or weakness
- Chest discomfort
- Shortness of breath or difficulty breathing
Not everyone experiences the same symptoms. Some infections can also occur without a fever, so it is important to pay attention to changes in how you feel.
How Do Respiratory Infections Spread?
Many respiratory infections spread through particles released when an infected person coughs, sneezes, talks, or breathes. Some infections can also spread through contaminated hands or surfaces when a person touches their eyes, nose, or mouth.
You can help reduce your risk of getting sick by washing your hands regularly, avoiding close contact with people who are sick, improving indoor ventilation, and covering coughs and sneezes. Staying up to date on recommended vaccines, including flu, COVID-19, and RSV vaccines when appropriate, can also help protect against severe illness.
When Should You Visit a Primary Care Clinic?
You should consider visiting a primary care clinic if your symptoms are getting worse, your fever persists, your cough does not improve, or you are concerned about your condition. A healthcare professional can evaluate your symptoms and determine whether testing for illnesses such as influenza, COVID-19, or other infections is appropriate.
Depending on your symptoms, your provider may recommend supportive care, prescribe medication when appropriate, or refer you for additional evaluation. Antibiotics do not treat viral infections and should only be used when a bacterial infection warrants them.
Seek emergency medical care if you experience severe difficulty breathing, persistent chest pain or pressure, new confusion, bluish or gray lips or skin, or other signs of a medical emergency.
How Can You Recover and Protect Your Health?
If you have a respiratory infection, getting adequate rest, drinking fluids, and following your healthcare provider’s recommendations can help support recovery. Stay home while you are sick and take precautions to reduce the risk of spreading the infection to others.
People at higher risk of complications, including older adults, young children, pregnant individuals, and people with certain chronic health conditions or weakened immune systems, should contact a healthcare professional promptly when symptoms develop. Early evaluation may be especially important because some antiviral treatments work best when started soon after symptoms begin.
Take Care of Your Respiratory Health
Recognizing the signs and symptoms of respiratory infections is an important step toward protecting yourself and your loved ones. Although many respiratory illnesses are mild, some can lead to serious complications if left untreated.
Do not ignore persistent or worsening symptoms. If you are feeling unwell, a visit to your primary care provider can help you understand your symptoms and determine the next steps for your health.
Your health matters. Stay informed, practice healthy habits, and seek medical care when you need it.
