As respiratory illnesses become more common during the colder months in Cleveland, it can be challenging to know whether you’re dealing with a cold, the flu, or COVID-19. These three illnesses share several symptoms, which makes it difficult to tell them apart without proper testing. However, there are certain differences in how each illness presents itself. In this blog, we’ll break down the key symptoms and what you need to know about distinguishing between COVID-19, the flu, and the common cold.

Recognizing the Common Cold

The common cold is caused by several different viruses, most notably rhinoviruses, and is generally mild. It primarily affects the upper respiratory tract and is easily spread from person to person, especially in settings where individuals are in close contact.

Typical symptoms of a cold include:

• Runny or stuffy nose
• Sneezing
• Mild cough
• Sore throat
• Watery eyes
• Mild fatigue
• Low-grade fever (in some cases)

Colds tend to have a slower onset, and symptoms are usually less severe than those of the flu or COVID-19. Unlike the flu, a cold does not typically cause body aches or high fevers, and symptoms like coughing are generally mild. Most people recover from a cold within 7 to 10 days, and symptoms can often be managed with rest, hydration, and over-the-counter remedies.

Recognizing the Flu

Influenza, or the flu, is a more serious illness that affects the respiratory system. While it shares some symptoms with the common cold, flu symptoms tend to appear suddenly and can be more severe. The flu is caused by influenza viruses and can lead to serious complications, especially for the elderly, young children, and those with compromised immune systems.

Common symptoms of the flu include:

• High fever (100°F or higher)
• Chills
• Severe fatigue and weakness
• Dry cough
• Body aches and muscle pain
• Sore throat
• Headache
• Stuffy nose (sometimes)

The flu differs from a cold in its rapid onset and more intense symptoms. People with the flu often experience severe fatigue and body aches that make it difficult to carry out daily activities. It typically lasts 5 to 7 days, though symptoms such as fatigue can linger for longer.

Vaccination is one of the most effective ways to prevent the flu. Even if you catch the flu after vaccination, your symptoms are likely to be milder and of shorter duration. Staying home, resting, and drinking plenty of fluids are key to recovery. If symptoms are severe or you are in a high-risk group, antiviral medications prescribed by a healthcare provider may help reduce the duration and severity of the flu.

Recognizing COVID-19

COVID-19, caused by the SARS-CoV-2 virus, has been a major concern since the pandemic began in 2020. Like the flu and cold, COVID-19 is a respiratory illness, but it can lead to a wider range of symptoms, varying from mild to severe.

Common symptoms of COVID-19 include:

• Fever
• Dry cough
• Shortness of breath
• Fatigue
• Body aches
• Headache
• Sore throat
• Diarrhea (less common)

COVID-19 symptoms can take longer to appear, with an incubation period of 2 to 14 days after exposure to the virus. While many people with COVID-19 experience mild to moderate symptoms, severe cases can lead to serious complications like pneumonia, difficulty breathing, and even death, particularly in high-risk individuals.

Key Differences to Watch For

Although there are many overlapping symptoms between these three illnesses, several factors can help you distinguish between them:

• Fever: While all three illnesses can cause a fever, high fevers (above 100°F) are more common with the flu and COVID-19 than with the common cold.
• Body Aches and Fatigue: Body aches and severe fatigue are much more common with the flu and COVID-19. Colds may cause mild fatigue, but they rarely result in the body-wide aches seen in flu cases.
• Respiratory Distress: Shortness of breath is a key warning sign of COVID-19 and can be a sign of a more severe case. While the flu can cause respiratory symptoms, it is less likely to result in serious breathing difficulties.

Testing is the best way to confirm whether you have COVID-19, the flu, or a cold. Rapid tests for COVID-19 and the flu are available at our clinic, allowing you to receive a diagnosis quickly and take appropriate action.

When to Seek Medical Attention

Most colds and mild flu cases can be managed at home with rest and over-the-counter treatments. However, there are certain circumstances where you should seek medical care:

• Difficulty breathing
• Persistent chest pain or pressure
• High fever that doesn’t respond to over-the-counter medications
• Severe dehydration
• Confusion or inability to stay awake

COVID-19 can lead to more severe complications, and individuals with underlying health conditions or those who are immunocompromised should be particularly vigilant. If you suspect you have COVID-19 or the flu and are experiencing any of these severe symptoms, it’s important to seek immediate medical attention.
