RSV vs Flu: Understanding the Shared Symptoms
Many symptoms of RSV and influenza are remarkably similar, often making self-diagnosis difficult and potentially delaying appropriate treatment. These shared symptoms can include:
- Fever: Both viruses can cause fever, although the severity and presentation differ.
- Cough: A cough is a hallmark symptom of both illnesses, but the character of the cough (dry, wet, wheezy) can provide clues.
- Runny or Stuffy Nose (Congestion): Nasal congestion is common in both RSV and flu infections.
- Sore Throat: Sore throat can accompany both infections, causing discomfort and difficulty swallowing.
- Sneezing: Sneezing, while not always present, can be a symptom of both RSV and the flu.
- Fatigue or Tiredness: Both illnesses leave individuals feeling exhausted and lacking energy.
- Headache: Headaches are another common symptom shared between the two viruses.
- Decreased Appetite: Loss of appetite is often reported in both RSV and flu infections.
Key Differences: Deciphering RSV vs Flu Symptoms
While the shared symptoms make differentiation challenging, key distinctions exist in the onset, severity, and specific symptoms exhibited:
1. Onset of Symptoms:
Flu: The flu typically strikes suddenly. Individuals often report feeling unwell almost immediately, experiencing a rapid onset of symptoms.
RSV: RSV symptoms usually develop more gradually, often beginning subtly like a common cold. The onset is typically 4 to 6 days after exposure to the virus.
2. Fever:
Flu: High fever (above 101°F) is frequently observed with influenza, often appearing abruptly, especially in children.
RSV: Fever in RSV infection can be low-grade, absent altogether, or more pronounced in infants and toddlers. Older children and adults might experience minimal or no fever.
