We are in the peak of the flu season and expectedly there has been a spike in the outbreak of flu and RSV (Respiratory Syncytial virus) all over the country. Most people often confuse RSV with flu or common cold. This is because both conditions tend to have the same symptoms. If you’re unsure how to differentiate the two, then this post is for you. This article is to help our readers identify Flu vs. RSV symptoms and how to tell the difference between the two.
What is Flu
The flu is a common respiratory infection caused by influenza virus; hence the name “flu”. Although flu comes and goes throughout the year, they are more prevalent during the colder seasons also known as the flu season.
Symptoms of Flu
- Sore throat
- Fever
- Cough
- Headaches
- Congestion
- Body aches
- Fatigue
Note: Flu symptoms are highly contagious and typically come suddenly and resolve on their own. The cycle usually lasts for a week after which the symptoms start fading off. Nonetheless, you can take antiviral treatment to manage the symptoms and help you get better faster.
What is RSV?
RSV is a respiratory infection that causes bronchiolitis in severe cases. The infection is caused by the respiratory Syncytial Virus (RSV), and hence named after it. Babies, young children and older adults or people with compromised immune systems are more susceptible to RSV. Healthy adults are less likely to get RSV and even when it does happen, it rarely leads to any complications.
Symptoms of RSV
RSV symptoms develop more slowly than the flu. The common symptoms include:
- Cough
- Runny nose
- Post Nasal drip
- Congestion and stuffiness
Less common symptoms include sore throat, fever, and body aches.
Symptoms gradually start developing after infection and reach its peak between day 3 to 5 days. Except in older adults and babies where complications might occur, RSV symptoms will most likely decline after a week.
How To Tell If You Have Flu or RSV
The best and surest way to tell if you have flu or RSV is to take a test. Taking a test cancels all speculations and can prevent you from making or treating a wrong diagnosis.
Nonetheless, knowing what to watch out for in your symptoms can also give you a clue on whether you have the flu or RSV.
Although both conditions show similar symptoms , Flu symptoms seem to start all of a sudden, no build ups at all. On the other hand, RSV symptoms have a more gradual approach. Besides, if people around you are down with the flu, it’s more likely that you’re down with Flu too and vice versa. Finally, you can check the CDC weekly flu map to check which condition is more prevalent in your community.
