During periods of seasonal change, such as India’s current spring season, viral infections tend to increase significantly. This is because many viruses thrive under varying levels of temperature and humidity.
While most people recover from viral infections without complications, recognising the warning signs can help prevent serious health issues.
Dr. Meenakshi Jain, Principal Director & HOD – Internal Medicine, Max Super Speciality Hospital, Patparganj, shares what you need to know:
Common Symptoms
“A viral fever caused by viruses such as influenza or rhinoviruses typically presents with a sudden onset of fever, along with chills, headache, muscle pain, fatigue, sore throat, cough, runny nose, and/or loss of appetite. In younger children and older adults, there may be a noticeable decrease in appetite. Symptoms usually peak within 24 to 72 hours (2–3 days) and generally resolve within a week.”
Why Seasonal Changes Matter
Seasonal transitions can weaken the immune system. Fluctuating temperatures, crowded environments, and low humidity (dry air) facilitate the spread of viruses through droplets and contaminated surfaces. In India, outbreaks are particularly common during the transition periods after winter and before the monsoon.
When to Worry
However, certain symptoms should not be ignored. If a fever exceeds 103°F for more than three days, does not respond to paracetamol, and is accompanied by signs such as difficulty breathing, chest discomfort, persistent vomiting, dehydration (dry mouth or no tears), severe headache, confusion, rash, stiff neck, abdominal pain, or seizures, immediate medical attention is necessary. Children who appear lethargic, avoid eye contact, or have diarrhoea should be evaluated promptly, while adults with persistent high fever should also seek medical advice. Symptoms like dehydration or breathing difficulty may indicate complications such as pneumonia.
Home Management
For home management, staying well-hydrated with fluids and ORS is essential, along with adequate rest. Paracetamol may be used for fever and pain relief, while lukewarm sponging can provide comfort. Isolating oneself helps prevent the spread of infection, and a light, nutritious diet supports recovery.
Prevention Tips
Preventive measures remain key. Regular handwashing, avoiding crowded places, and covering the mouth while coughing or sneezing can reduce transmission. Consuming immunity-boosting foods such as citrus fruits and yogurt, ensuring proper ventilation at home, and wearing masks in public during peak seasons can further lower risk. Flu vaccination is also recommended, especially for high-risk groups.
Most viral fevers are mild, but staying vigilant and recognising warning signs can make a crucial difference.
