What is the Difference Between RSV and Influenza?

Respiratory Syncytial Virus (RSV) and Influenza (flu) are both contagious respiratory infections caused by different viruses. The flu is caused by the influenza virus, while RSV is caused by the respiratory syncytial virus. Symptoms for both infections can be similar, making it difficult to differentiate between them without proper testing. Here are some key differences between RSV and Influenza:

• Symptoms: Both RSV and influenza can cause fever, cough, and shortness of breath. However, RSV symptoms can also include fatigue, stuffy nose, sneezing, fast/short breaths, flaring nostrils, wheezing, and grunting. Influenza symptoms may include chills, headache, body aches, a dry cough, and a stuffy nose.
• Age Groups Affected: RSV can infect anyone but is most dangerous in infants and the elderly. Influenza can affect individuals of all ages, with higher risk of complications for young children, older adults, and those with underlying health conditions.
• Diagnosis: Testing is the only definitive way to distinguish between RSV and influenza, as symptoms can be similar.
• Treatment: There is no specific treatment for either RSV or influenza, with both relying on supportive care, including comfort measures and management of symptoms.
• Prevention: Vaccines are available for both influenza and RSV. The CDC recommends getting vaccinated against influenza every year for everyone aged 6 months and older. For RSV, there are vaccines like Nirsevimab for babies younger than 8 months of age in their first RSV season and RSVpreF for pregnant people to protect their infants from RSV.

Comparative Table: RSV vs Influenza

Here is a table comparing the differences between RSV (Respiratory Syncytial Virus) and Influenza:

Both RSV and Influenza are common respiratory illnesses caused by different viruses, and they share similar symptoms in many cases. However, there are key differences that set them apart, such as the incubation period, the onset of symptoms, and the duration of symptoms. It is essential to consult a healthcare professional for proper diagnosis and treatment, as the severity of symptoms can vary from person to person.
