Fall allergy season in Kentucky overlaps with cold and flu season, creating a challenging period for residents trying to distinguish between outdoor allergens and viral infections like COVID-19, RSV, and the flu.
Fall allergy season in Kentucky begins in mid-August with the arrival of ragweed and lasts until the first harsh freeze. Ragweed, alongside tree and grass pollen, acts as a primary driver of seasonal symptoms across the region. At the same time, viral respiratory infections begin to rise in late October and November, bringing influenza, respiratory syncytial virus (RSV), the common cold, and COVID-19 into circulation together.
The Centers for Disease Control and Prevention notes that flu activity typically peaks between December and February. Because both seasonal allergies and viral infections share symptoms such as coughing, runny noses, and congestion, identifying the exact cause of an illness requires careful attention to specific bodily signs.
Distinguishing Allergies From The Common Cold
While allergies and viral infections overlap significantly, key differences help separate them. Allergies commonly cause persistent itching in the eyes, nose, or throat, a symptom that a cold usually does not produce, the source reported. Allergies never cause fever or body aches.
Viral respiratory infections frequently trigger sore throats, fatigue, and body aches alongside standard respiratory congestion. Because differentiating between a common cold and other viral illnesses can prove difficult, medical providers recommend an in-person evaluation for moderate to severe symptoms.
When To Seek Professional Medical Care
Mild seasonal allergies generally respond well to over-the-counter treatments at home. Patients can manage symptoms using daily or as-needed oral antihistamines, decongestants, or nasal sprays designed to reduce swelling in nasal passages. An allergist should be consulted if symptoms remain uncontrolled by medication and disrupt daily life.
For viral respiratory infections, individuals should see a healthcare provider if symptoms persist beyond 10 to 14 days or if they suddenly return after an initial recovery. Emergency care is necessary for serious indicators such as trouble breathing, chest pain, confusion, difficulty waking, seizures, severe weakness, or dehydration.
Measures to Reduce Infection Risks
Dr. Sarah Marks, assistant professor of Family and Community Medicine at UK HealthCare Turfland, outlined steps residents can take to reduce infection risks and protect others, the source reported. Recommendations include discussing vaccinations with a healthcare provider, practicing good hygiene by washing hands frequently, sanitizing high-touch surfaces, and covering coughs and sneezes.
Individuals who feel unwell should stay home from work or school to limit contact with others. Those who must go out while sick are advised to wear a face covering to prevent spreading illness.
