Delhi H1N1 Surge Prompts Warnings About Breathing Complications
H1N1 is a flu virus that usually causes fever, cough and tiredness.
Most people get better with rest, fluids and other supportive care.
Sometimes the infection reaches the lungs and causes pneumonia.
This can make it hard for the body to get enough oxygen.
Trouble breathing while resting, blue lips, chest pain or confusion are emergency warning signs.
A pulse oximeter can help check oxygen, but one unusual reading should be checked properly.
People should not start oxygen, antibiotics or steroids without medical advice.
Doctors say people with worsening symptoms should seek care quickly, especially if they are older or have other health problems.
Delhi recorded 1,449 H1N1 cases through August 12, 2026, compared with 229 during the same period last year.
Doctors say most H1N1 patients recover with supportive care, but some develop pneumonia and serious breathing complications.
Warning signs include worsening breathlessness, low oxygen saturation, chest pain, blue lips, confusion and rapid breathing.
India’s seasonal influenza protocol recommends oxygen therapy for respiratory distress with oxygen saturation below 90%.
Older adults, young children, pregnant women and people with chronic illnesses face higher risks of severe influenza.

Urgent medical assessment
Reassurance and supportive care
Meaning of breathing symptoms
Urgent medical assessment
Doctors and the World Health Organization identify worsening breathlessness, hypoxia, rapid breathing, chest pain and blue lips as signs requiring urgent medical review.
Reassurance and supportive care
Doctors stress that not every cough, fever or mild episode of breathlessness means severe H1N1, and most patients recover with supportive care.
Use of oxygen
Urgent medical assessment
Oxygen or ventilatory support may be needed when low oxygen is accompanied by respiratory distress or severe lung disease.
Reassurance and supportive care
People should not self-administer oxygen based only on a single pulse-oximeter reading; readings can be affected by cold fingers, movement, poor circulation or incorrect positioning.

Quotes
Dr Manoj Kumar Goel
Principal Director and Unit Head of Pulmonology and Sleep Medicine at Fortis Memorial Research Institute, Gurgaon
“Low oxygen saturation levels, inability to speak and walk, pale bluish lips, extreme drowsiness, and confusion signifies a serious urgency and requires immediate intervention.”

“A serious case of this could cause pneumonia thereby impeding gas exchange, an adequate transmission of oxygen to the bloodstream from the lungs.”
