Flu, RSV, COVID, or Allergies: How to Tell the Difference

During late winter and early spring, many South Texas patients experience symptoms such as cough, congestion, fatigue, and sore throat. These symptoms can be caused by several conditions, including the flu, COVID, RSV, or seasonal allergies.

Because symptoms can overlap, it can be difficult to know which illness you may have.

Flu Symptoms

The flu often appears suddenly and may include:

• Fever or chills

• Body aches

• Fatigue

• Headache

• Cough

• Sore throat

Flu symptoms are typically more intense than a common cold and may last several days.

COVID Symptoms

COVID symptoms vary widely but may include:

• Fever

• Cough

• Fatigue

• Headache

• Sore throat

• Congestion

• Loss of taste or smell in some cases

Symptoms can range from mild to severe and may last longer than the flu.

RSV Symptoms

Respiratory Syncytial Virus, often called RSV, commonly affects young children but can also affect adults. Symptoms include:

• Runny nose

• Cough

• Fever

• Wheezing

• Difficulty breathing in severe cases

RSV is especially concerning for infants and older adults.

Seasonal Allergy Symptoms

Allergies occur when the immune system reacts to environmental triggers such as pollen. Common symptoms include:

• Sneezing

• Runny nose

• Itchy eyes

• Nasal congestion

• Postnasal drip

Unlike infections, allergies do not cause fever or body aches.

When to Visit Urgent Care

You should consider visiting urgent care if symptoms include:

• Fever lasting more than two days

• Difficulty breathing

• Severe fatigue

• Persistent cough

• Symptoms that worsen over time

Urgent care providers can evaluate symptoms and determine whether testing or treatment is needed.
