Delhi Sees Rise in H1N1 Cases; Agilus Diagnostics Highlights Timely Testing and Early Care

New Delhi: Delhi is witnessing increased seasonal influenza activity, with 1,777 H1N1 cases reported through August 20, 2026, according to recent reports. Agilus Diagnostics has also observed a H1N1 positivity rate of nearly 30% at its Reference Laboratory over the past week among tested individuals, a press release said.

As per the press statement, while the rise in cases warrants awareness and appropriate medical attention, there is no reason for undue panic. H1N1 is not a new virus. The A(H1N1)pdm09 virus that caused the 2009 pandemic has continued to circulate globally as a seasonal influenza virus and is now among the viruses that cause seasonal flu. Seasonal fluctuations in influenza activity can occur due to several factors, including weather conditions, population immunity and patterns of transmission.

Highlighting the importance of timely diagnosis and medical care, Dr. Yoginder Pal Singh, Head – HLA and Molecular Biology at Agilus Diagnostics, said, “The rise in H1N1 cases is a reminder that seasonal respiratory infections can spread rapidly, particularly in crowded and poorly ventilated environments. Influenza symptoms can overlap with other respiratory infections, making prompt testing and medical evaluation important, especially for high-risk individuals. Early diagnosis can help doctors consider timely antiviral treatment where appropriate. Common influenza symptoms may include fever, cough, sore throat, body aches, headache, fatigue, chills, and a runny or blocked nose. Because these symptoms can resemble COVID-19 and other respiratory infections, symptoms alone may not establish the cause. Based on individual symptoms and medical history, physicians may utilise diagnostic tools such as RT-PCR testing or comprehensive respiratory panels. Clinicians may also order a Complete Blood Count (CBC) or C-Reactive Protein (CRP) test where clinically appropriate.”

 Antiviral treatments are most effective when initiated within the 48-hour window from symptom onset. High-risk individuals should seek medical advice promptly and take antiviral medication only as prescribed by a physician. Vulnerable groups, including young children, older adults, pregnant women, people with diabetes, heart or lung disease, asthma, and those with compromised immunity, face a higher risk of severe flu complications, the statement further said.

Prompt medical attention is recommended for warning signs such as difficulty breathing, persistent or high fever, chest discomfort, confusion, severe weakness, dehydration, or falling oxygen saturation.

Preventive measures:

• Stay home when unwell and minimise close contact with others.
• Wear a well-fitting mask in crowded indoor spaces, particularly when symptomatic.
• Cover your mouth and nose while coughing or sneezing and wash your hands regularly.
• Improve ventilation in homes, offices and other indoor spaces.
• Stay hydrated and avoid self-medication, particularly antibiotics and antivirals.
• Consult a doctor about seasonal influenza vaccination if you are at higher risk.
• During the monsoon, avoid stagnant water to reduce the risk of mosquito-borne infections such as dengue.

With multiple seasonal infections potentially circulating, awareness, timely evaluation and appropriate testing can help ensure the right care at the right time. The current rise in H1N1 activity calls for caution and preparedness, not panic.
