Respiratory Syncytial Virus: What Are The Symptoms And Risk Factors One Should Know

Respiratory Syncytial Virus (RSV) is a viral infection that affects the respiratory tract. While it usually causes mild cold-like symptoms in healthy individuals, it can lead to more severe respiratory issues, especially in infants, older adults, and individuals with weakened immune systems.

Even in India, RSV is widespread. According to research published in the National Library of Medicine, RSV detection rates in younger children, ages zero to five, range from 2.1% to 62.4%. This number is higher than in other age groups.

Symptoms of RSV Infection

Coughing

Persistent coughing, often accompanied by mucus production, is a common symptom of RSV infection.

Congestion

Nasal congestion and difficulty breathing may occur, particularly in infants who have smaller airways.

Fever

A fever is a typical response to viral infections, and RSV is no exception. It can range from mild to moderate.

Wheezing

Wheezing and difficulty breathing, especially during exhaling, can be observed, particularly in infants and young children.

Runny Nose

Excessive nasal discharge is common, contributing to congestion and discomfort. As per MayoClinic, the fluid might vary from thin and transparent to thick and yellow-green. The fluid may trickle or stream from the nose, down the back of the throat, or both. Postnasal drip occurs when it flows down the back of the throat.

Decreased Appetite

Individuals, especially infants, may show a decreased interest in feeding due to difficulty breathing.
