Understanding the Contagious Nature of Upper Respiratory Infections
Upper respiratory infections (URIs) are highly contagious and can easily be transmitted from one person to another. It is important to note that individuals can spread the infection even before they experience any symptoms. This means that many people may unknowingly transmit the virus before taking necessary precautions. However, by following simple hygiene practices, we can effectively reduce the spread of URIs.
Causes of Upper Respiratory Infections
Upper respiratory infections, including the common cold and influenza, are primarily caused by viruses. When infected, the body’s immune system is activated to fight off the invading viruses. It is important to note that treatment for these infections focuses on managing symptoms rather than directly targeting the root cause.
Typical symptoms of an upper respiratory infection include a runny nose, post-nasal drip, cough, and nasal congestion.
