A cough, sore throat, fever, or sudden fatigue can leave you wondering whether you have COVID-19, the flu, or another respiratory illness. Since these illnesses share similar symptoms, it isn’t always easy to tell them apart.
COVID-19 continues to circulate through San Antonio, making it important to recognize potential symptoms and understand when medical attention may be necessary.
While many people experience mild symptoms and recover at home, others may develop complications that require medical evaluation. Knowing what to expect, when to get tested, and which warning signs to take seriously can help you make informed decisions about your health.
What Are the Most Common COVID-19 Symptoms?
COVID-19 is a contagious respiratory illness caused by the SARS-CoV-2 virus. Symptoms can range from mild to severe and may appear 2 to 14 days after exposure.
According to the Centers for Disease Control and Prevention (CDC), common COVID-19 symptoms include:
- Fever or chills: An elevated body temperature, sometimes accompanied by shivering or sweating.
- Cough: A new or persistent cough that may be dry or produce mucus.
- Sore throat: Throat irritation, discomfort, or pain when swallowing.
- Congestion or runny nose: Nasal symptoms that can resemble a common cold.
- Fatigue: Unusual tiredness or weakness that makes everyday activities more difficult.
- Headache: Mild to severe headaches that may occur alongside other symptoms.
- Muscle or body aches: Generalized soreness or discomfort throughout the body.
- Shortness of breath: Difficulty breathing or feeling unusually winded.
- Loss of taste or smell: A noticeable change in your ability to taste or smell.
- Digestive symptoms: Nausea, vomiting, or diarrhea.
Not everyone experiences the same symptoms. Some individuals may have only mild congestion or fatigue, while others develop more noticeable respiratory symptoms. Reminder: COVID-19 can also occur without a fever.
How Can You Tell the Difference Between COVID-19, the Flu, and a Cold?
COVID-19, influenza, and the common cold are caused by different viruses, but they can produce many of the same symptoms.
For example, coughing, congestion, sore throat, and fatigue are common across all three illnesses.
The flu often develops suddenly and may cause significant body aches, fever, and fatigue. A common cold tends to produce milder symptoms, particularly congestion, sneezing, and a sore throat. COVID-19 can resemble either illness.
However, symptoms alone cannot reliably distinguish COVID-19 from influenza or other respiratory infections.
If you are experiencing respiratory symptoms in San Antonio, diagnostic testing may help identify the cause. Depending on your symptoms and medical history, a healthcare provider may recommend testing for COVID-19, influenza, or other infections.
When to Test for COVID-19?
Testing can help determine whether your symptoms are caused by COVID-19 and provide useful information about treatment and preventing transmission. You should consider COVID-19 testing when you develop symptoms associated with the virus, particularly if you have recently been exposed to someone who tested positive.
Testing may also be important if you:
- Have symptoms that are not improving
- Live with someone at higher risk of serious illness
- Have underlying medical conditions that increase your risk of complications
- Need to determine whether COVID-19 treatment may be appropriate
At-home antigen tests can be useful, but a single negative result does not necessarily mean you don’t have COVID-19.
If you have symptoms and receive a negative antigen test result, the FDA recommends repeating the test 48 hours later. A molecular test, such as a PCR test, may also be appropriate depending on your situation.
For people who are at greater risk of severe illness, it is important not to delay contacting a healthcare provider while waiting for repeat test results.

When Should You Visit Urgent Care for COVID-19 Symptoms?
Although mild COVID-19 symptoms can often be managed at home, some situations warrant evaluation at an urgent care facility.
Consider visiting urgent care if you experience:
- A fever that persists or returns after improving
- A cough that becomes progressively worse
- A sore throat or congestion that interferes with normal activities
- Difficulty maintaining adequate hydration
- Symptoms that are not improving as expected
- Concerns about complications or existing medical conditions
Urgent care may also be helpful when you need testing to determine whether your illness is COVID-19, influenza, or another respiratory infection.
Older adults and people with certain medical conditions should seek medical advice early because they may benefit from antiviral treatment. Depending on the medication, COVID-19 treatment generally needs to begin within five to seven days of symptom onset.
For individuals experiencing non-life-threatening symptoms, a walk-in clinic in San Antonio can provide medical evaluation and help determine the appropriate next steps.
What COVID-19 Symptoms Require Emergency Care?
While most COVID-19 infections do not require emergency treatment, serious complications can occur.
According to the CDC, emergency warning signs of COVID-19 include:
- Trouble breathing: Severe breathing difficulty or respiratory distress.
- Persistent chest pain or pressure: Ongoing discomfort or pressure in the chest.
- New confusion: Sudden changes in awareness, behavior, or mental clarity.
- Inability to wake or stay awake: Unusual difficulty remaining conscious or responsive.
- Changes in skin, lip, or nail bed color: Pale, gray, or blue discoloration, depending on skin tone.
These symptoms may indicate a medical emergency and should not be ignored.
If you or someone nearby experiences these warning signs, call 911 immediately.
Patients experiencing severe respiratory symptoms may require emergency evaluation, monitoring, and additional diagnostic testing.
