"Is it COVID or just allergies?" This question has become increasingly complex as COVID variants evolve. Dr. Krikor Manoukian, Medical Director at HeyAllergy and board-certified allergist, provides expert guidance: "While some symptoms overlap, there are key differences that can help you make an informed decision about your health."

Quick Symptom Comparison Guide

Symptom COVID-19 Allergies
Fever Common Never
Loss of Taste/Smell Sometimes Rare/Mild
Itchy Eyes Rare Very Common
Sneezing Sometimes Common
Body Aches Common Never
Fatigue Common Sometimes
Sore Throat Common Rare
Cough Common (Dry) Sometimes
Runny/Stuffy Nose Sometimes Very Common

Three Key Questions to Ask Yourself

Dr. Manoukian recommends asking yourself these questions:

  1. Do you have a fever or body aches?
    • Yes → Likely COVID, get tested
    • No → Could be allergies
  2. Are your eyes itchy?
    • Yes → Likely allergies
    • No → Consider COVID testing
  3. Have your symptoms changed suddenly?
    • Yes → Consider COVID testing
    • No → More likely allergies

Unique COVID Symptoms (Get Tested If You Have These)

Current COVID variants typically cause:

  • Fever (100.4°F or higher)
  • Sudden loss of taste or smell
  • Body aches and chills
  • Severe fatigue
  • Shortness of breath

"These symptoms rarely occur with allergies," explains Dr. Manoukian. "If you experience any of these, especially fever or loss of taste/smell, seek COVID testing promptly."

Clear Signs of Allergies

Allergy symptoms typically include:

  • Itchy, watery eyes
  • Clear nasal discharge
  • Sneezing fits
  • Symptoms that worsen outdoors
  • History of seasonal allergies
  • Improvement with antihistamines

"Allergy symptoms tend to be consistent and predictable," notes Dr. Manoukian. "They often correlate with specific triggers or seasons."

When Symptoms Overlap

Some symptoms can occur in both conditions:

  • Coughing
  • Congestion
  • Fatigue
  • Headache
  • Sore throat

How to differentiate:

  • COVID symptoms typically appear suddenly
  • Allergy symptoms often follow patterns
  • COVID may include fever and body aches
  • Allergies usually involve itching

Consider these factors when evaluating your symptoms:
