Hospitals in Delhi have reported a sharp increase in symptoms such as high -class fever, sore throat, frequent body pain, headache and weakness characterized flu.

Unlike the common flu, these symptoms do not effectively react to standard over-the-counter drugs such as paracetamol.

Medical experts have identified the H3N2 Influenza A virus as a major stress responsible for this severe outbreak, in which the recovery time extends for a week or more. In some cases, patients need to be hospitalized due to complications.

Dr. Vikas Maurya, Senior Director and HOD, Respiratory Medicine and Respiratory Critical Care, Fortis Hospital, Shalimar Bagh, Delhi said that what we are seeing this year, such as during a long monsoon season, viral infections easily spread from person to person. Seasonal flu is a broad term for many respiratory viruses, while H3N2 influenza is a distinct subtlety of A which is currently prominent.

Health professionals urge vigilance and early identity, especially during a prolonged monsoon season that increases the spread of viruses.

Prolonged fever and respiratory issues distinguish this infection from typical seasonal flu, which highlight the need for early medical intervention.

“In recent months, many patients have stated that their cold and cough symptoms last longer than normal. It is partially due to stress of H3N2 influenza, which causes more frequent cough, fatigue, and low-grain fever than common cold viruses,” Dr.

Additionally, changes in weather, pollution and weak immunity are also contributing factors due to poor sleep and nutrition. “While the common cold is usually solved in 5-7 days, infections associated with H3N2 may last in some cases,” Dr. Mittal said.

Are children being affected by this viral infection?

Children are usually present with cough, fever, nasal congestion and sometimes wheezing.

“Yes, the children are definitely affected, and in fact, they are more weak. Their immunity is still developing, and because they are in close contact with other children in schools and decare centers, the virus is easily spread,” Dr. Mittal said.

When should anyone ideally go to a doctor? He said, “Most colds improve with home care, but if the cough deteriorates, or if chest pain or difficulty in breathing, fever remains beyond three days, but medical advice should be sought.”

While both common cold and H3N2 virus similar symptoms such as fever, sore throat, cough, and cold, H3N2 often brings pneumonia to lung complications, in some cases, prolonged fever, frequent coughs, and in some cases.

If the fever does not decrease within a few days or with trouble with breath and chest, it is important to look for medical care.

The head of the Emergency of PSRI Hospital, Dr. Prashant Sinha said, “Another issue is that people often relax self-method or delays, which further the disease. Adequate hydration, rest and medical supervision where necessary, are very important.”

He said, “In children, infection can also give rise to complications such as ear infections or bronchitis if not properly managed. Parents should closely monitor the symptoms, especially if a child has asthma or an underlying health problem,” he said.

In various hospitals, the Out-Rogi Department (OPD) present high grade fever and chest congestion in more than half of cases, doctors are advising to demand immediate check-up and most important, comfort and hydration.
