Everything You Need to Know About Sick Season

Is it a Cold, Sinus Infection, Flu or COVID? How to Tell the Difference

Feeling under the weather? It can be tough to know whether you’re dealing with a cold, sinus infection, the flu or even COVID-19 as many of the symptoms overlap. Understanding the differences can help you decide when to rest and when to seek medical advice.

Cold vs. Sinus Infection

Both colds and sinus infections often begin with similar symptoms like a runny nose, congestion and a sore throat. Colds are viral infections of the upper respiratory tract, caused by over 200 different viruses, and typically resolve on their own. Sinus infections, however, can be either viral or bacterial. They occur when the sinus passageways become blocked, leading to trapped mucus that can foster the growth of bacteria.

Sinus infections often clear up on their own, but if symptoms worsen or persist more than 10 days or worsen, it may be time to consult a doctor about antibiotics.

Flu and COVID

Flu and COVID-19 share many symptoms with colds and sinus infections, but tend to be more severe. Both can cause fever, body aches and fatigue. If you’re unsure whether you have the flu or COVID, testing is the best way to differentiate between the two.

When to Seek Medical Help:

• Symptoms last more than 10 days or worsen after initially improving.
• You experience severe pain or pressure in your face.
• High fever, shortness of breath, or other flu/COVID symptoms arise.

Home Remedies

For most colds, sinus infections and mild flu cases, rest, fluids and over-the-counter treatments like saline sprays, steroid nasal sprays (fluticasone) or pain relievers (acetaminophen or ibuprofen) can help ease symptoms. If you suspect bacterial sinusitis, consult your doctor, as antibiotics may be necessary.

Stay Healthy

"During this flu/COVID season, take simple steps to stay safe: get vaccinated, wash your hands regularly and wear masks when needed. Together, we can help protect our communities,” said Dr. Manuj Rattan, Trinity Health IHA Medical Group, Primary Care - Cherry Hill Village.

Stay mindful of worsening symptoms, and contact your health care provider for guidance, especially if you're unsure whether you need antibiotics or further testing. Looking for a provider before sick season sets in? Find a Trinity Health Michigan doctor near you.
