Influenza (commonly known as the flu) and Respiratory Syncytial Virus (RSV) are both highly contagious viral infections that affect the respiratory system. However, there are significant differences between the two. 

The flu is caused by influenza viruses and is notorious for causing seasonal epidemics globally, leading to severe illness and even death in high-risk populations. On the other hand, RSV primarily affects infants and young children, causing bronchiolitis, pneumonia and severe respiratory illness. 

While both these infections share common symptoms like cough, fever, and runny nose, their epidemiology, risk factors, and potential complications differ. Further understanding of these differences is vital for effective prevention, diagnosis, and treatment strategies.

Facts About The Flu and RSV

Flu (Influenza)

The flu, medically known as influenza, is a contagious respiratory illness caused by influenza viruses. It can affect individuals of all ages and is characterized by a range of symptoms such as elevated fever, cough, sore throat, muscle aches, and fatigue. It's important to note that while most individuals recover from the flu, it can lead to severe complications, especially for those with weakened immune systems or underlying medical conditions.

Flu Symptoms

The flu often makes a sudden entrance, presenting symptoms that can vary in severity. Keep an eye out for elevated fever (typically exceeding 100°F), persistent cough, sore throat, muscle soreness and discomfort, and fatigue.

RSV Symptoms

RSV (Respiratory Syncytial Virus)

RSV is a common respiratory virus that impacts individuals across various age groups. It particularly poses a heightened risk among infants and older adults. Initially, RSV symptoms may resemble those of a common cold, including coughing and sneezing, fever, and breathing difficulties. However, in severe cases, RSV can progress to respiratory distress, which is especially concerning in infants and elderly individuals.

RSV symptoms may initially mimic a common cold but can evolve into more pronounced respiratory issues, including:

•  persistent coughing
•  rapid breathing
•  wheezing or respiratory distress.

Tips on Preventing the Flu

• The CDC strongly recommends annual flu vaccination as the primary and most crucial measure to safeguard against influenza viruses.
• It is advisable for all individuals aged 6 months and older to receive an annual flu vaccine, ideally before the end of October. Here at AFC, we also offer “fluzone” high dose flu shots for seniors and  those 65 and up.
• Avoid close contact with individuals who are currently unwell.
• If you experience symptoms of illness, minimize contact with others as much as possible to reduce the risk of virus transmission.
• Practice proper cough and sneeze etiquette.

In the case of influenza, the CDC advises individuals to stay home for at least 24 hours after their fever has subsided, with the exception of seeking medical care or fulfilling essential needs. Fever should naturally subside without the need for fever-reducing medications.

How To Protect Yourself from RSV

• The CDC recommends that all infants under 8 months of age receive nirsevimab to protect them during their initial RSV season.
• Consider undergoing a Nasal swab RSV test at AFC Urgent Care Danbury East.
• An RSV vaccine is available to shield adults aged 60 years and older from RSV disease. Although we do not offer the RSV vaccine at AFC, please check with your health provider or local pharmacy as they can help point you in the right direction on how to get it.
• Older adults are at a greater risk than their younger counterparts for experiencing severe 
• RSV-related complications due to the gradual weakening of their immune systems.
• When coughing or sneezing, use a tissue or your shirt sleeve to cover your mouth and nose instead of your hands.
