H1N1 Alert: Fever Isn’t The Only Warning, 4 Symptoms That Signal Serious Complications
ABP Live Lifestyle | August 21, 2026 10:11 PM CST

Cases of swine flu, also known as H1N1 influenza, are being reported in several areas, including Delhi. Since its early symptoms can resemble those of a common viral fever, the infection may sometimes be mistaken for a routine illness. While many people recover without serious complications, swine flu can become severe in some cases. Older adults, young children, pregnant women and people with existing health conditions need to be particularly careful. Doctors advise patients not to monitor fever alone. Certain symptoms can indicate that the infection is becoming more serious and may require prompt medical attention.

Difficulty Breathing Or Chest Discomfort

Breathing problems are among the symptoms that should not be ignored. If a person is breathing unusually fast, feels short of breath or develops difficulty breathing, medical advice should be sought promptly. In more serious cases, influenza can affect the lungs and may lead to complications such as pneumonia. Chest discomfort or persistent pain along with breathing difficulties is another reason to seek medical evaluation.

Extreme Weakness Or Persistent Dizziness

Feeling tired or weak is common during an infection. However, severe weakness that makes it difficult to sit or stand normally, persistent dizziness or fainting should not be taken lightly. Patients should also remain alert if their condition suddenly worsens after initially appearing to improve. A return or worsening of fever, severe cough or breathing difficulties warrants medical attention.

Blue Lips Or Face

A bluish colour around the lips or face can be a sign that the body is not getting enough oxygen. This is a potentially serious warning sign and requires immediate medical attention. Rather than waiting for the fever to settle, patients showing such symptoms should seek urgent care.

Who Needs Extra Caution?

Young children, older adults, pregnant women and people with asthma or other lung conditions may be at greater risk of complications from influenza. They should be monitored closely when they develop flu-like symptoms. If symptoms become severe or worsen suddenly, it is important to consult a doctor promptly rather than relying on home treatment alone.
