H1N1 flu cases and symptoms in Delhi
ICMR Statement on H1N1 Swine Flu Strain: Amid a rise in seasonal flu cases in Delhi, public concern about H1N1 is growing. Meanwhile, a senior scientist at the Indian Council of Medical Research has clarified that no new strain of the H1N1 virus has emerged in the country. According to scientists, there is no need to panic at this time. The viruses circulating in India are seasonal strains and have been in circulation since 2025. They also closely match the strains included in the vaccine recommended for the Northern Hemisphere.
According to ICMR scientists, the Influenza A (H1N1)pdm09 viruses currently circulating in India belong to the A/Missouri/11/2025 (H1N1)pdm09-like virus strain. These viruses belong to clade 6B.1A.5a2a and subclade D.3.1.1. The scientists stated that the situation is being continuously monitored and the spread of the virus is being monitored through regular surveillance.
H1N1 cases rise in Delhi
This information from ICMR comes at a time when Delhi is seeing an increase in seasonal influenza cases. As of August 20, 1,777 cases of H1N1 had been reported in Delhi. A total of 2,392 cases of Influenza A had been reported. Thus, H1N1 remains the predominant subtype of Influenza A cases reported this year.
Dr. Randeep Guleria, Chairman of Internal Medicine and Respiratory and Sleep Medicine at Medanta Hospital, also spoke about the increase in cases. He explained that H1N1 cases increase every year during the monsoon season, but this time the number of cases appears to be comparatively higher.
What are the common symptoms of H1N1?
According to Dr. Guleria, most patients are experiencing symptoms such as fever, cough, sore throat, and body aches. Many patients are also experiencing a dry cough. These symptoms are common during seasonal influenza. However, the disease's effects vary from patient to patient. The infection can be severe, especially in the elderly, young children, and those with pre-existing medical conditions. These individuals may also experience symptoms such as chest tightness, difficulty breathing, and viral pneumonia.
What symptoms should not be ignored?
Dr. Neeraj Nischal, Professor of Medicine at AIIMS, explained that certain symptoms should prompt immediate medical attention. These include difficulty breathing, chest pain, low oxygen levels, persistent or increasing fever, confusion, extreme weakness, or dehydration. He also highlighted a specific condition as important: If a patient's health seems to improve for a period of time and then suddenly deteriorates again, this should not be dismissed as normal. A sudden deterioration after recovery could be a sign of another problem.
