🤧 Allergies vs. Viral & Bacterial Illness: How to Tell the Difference
With so many people dealing with congestion, coughing, and fatigue right now, it can be hard to know… is it allergies or an infection? Understanding the difference can help you choose the right treatment and avoid unnecessary antibiotics.
🌼 Why Are Allergy Symptoms Flaring Up?
Allergy symptoms can worsen due to:
• Seasonal pollen (trees, grasses, weeds)
• Weather changes (wind, temperature swings)
• Indoor allergens (dust mites, pet dander, mold)
Allergies are your immune system reacting to harmless triggers not to an infection.
🔎 Allergy Symptoms
• Sneezing
• Itchy nose, eyes, or throat
• Clear, watery nasal drainage
• Nasal congestion
• Watery or red eyes
• Symptoms that last weeks or months
• No fever
Allergies typically do not cause body aches, significant fatigue, or fever.
🤒 Viral Illness Symptoms (Cold, Flu, COVID, etc.)
• Fever
• Body aches
• Fatigue
• Sore throat
• Cough
• Congestion (may start clear, then thicken)
• Symptoms usually improve within 7–10 days (longer for some viruses)
🦠 Bacterial Infection Symptoms
• Persistent or worsening symptoms after 7–10 days
• High fever
• Thick yellow/green mucus with facial pain (sinus infection)
• Severe sore throat with fever
• Symptoms that initially improve, then suddenly worsen
💊 Important Reminder About Antibiotics
Antibiotics:
• Do NOT treat allergies
• Do NOT treat viruses
• Should only be used when truly necessary
⚠️ Unnecessary antibiotic use can lead to resistance and unwanted side effects.
🛡️ Ways to Help Prevent Illness
• Wash hands frequently
• Avoid touching your face
• Stay home when sick
• Get recommended vaccines
• Maintain a healthy diet and adequate sleep
• Manage stress
