Delhi records sharp H1N1 rise, prompting doctors to closely monitor severe and persistent symptoms.
Delhi is seeing a marked increase in H1N1 influenza, commonly known as swine flu, this monsoon, with the number of confirmed cases crossing 1,400 this week. The capital had reported 1,449 cases as of August 12, more than six times the 229 cases recorded during the corresponding period last year. The rise is being reflected in hospital outpatient departments, where doctors are encountering more people with high fever, cough, sore throat, fatigue and body ache. While most patients recover without serious complications, physicians are keeping a closer watch on those whose symptoms persist or worsen. A doctor working in a Delhi hospital’s respiratory medicine department said the increase has been noticeable over the past few weeks. “We are seeing more patients coming in with influenza-like symptoms, particularly prolonged fever and cough.
The important thing is to identify those who are beginning to develop breathing difficulty rather than treating every case as an ordinary viral infection,” the doctor said, requesting anonymity as he was not authorised to speak to the media. Another physician at a private hospital in south Delhi said the monsoon period was bringing several respiratory infections at the same time, making clinical assessment important. “There is a lot of overlap in symptoms. A patient may initially assume it is just a seasonal fever, but persistent fever, severe weakness or worsening cough needs attention. We are being more careful about whom we test for influenza,” Dr Kiran said. The latest rise comes as Delhi moves through a period when influenza and other seasonal infections are circulating together. Doctors say this can make self-diagnosis particularly difficult because fever, headache and body ache can occur in several illnesses. For a healthy adult, H1N1 is generally a self-limiting viral infection.
The greater concern is among people who are more likely to develop complications, including older adults, young children, pregnant women and those with chronic respiratory, cardiac or metabolic conditions. A senior doctor at a government hospital said the severity of illness, rather than the positive test alone, should determine the level of concern. “A positive H1N1 report does not mean that every patient needs hospitalisation. What matters is the clinical condition. If oxygen levels fall, breathing becomes difficult or the patient is deteriorating, we don’t advise them to wait at home,” the doctor said, also requesting anonymity. Hospitals are also watching for patients who develop pneumonia or other complications after several days of flu-like illness.
At the same time, doctors are cautioning against indiscriminate use of antibiotics. Since H1N1 is caused by influenza virus, antibiotics do not treat the infection. Antiviral medicines may be prescribed in appropriate cases, particularly when a patient is at higher risk or has more severe disease. The Delhi government has said its hospitals are fully prepared to deal with the increase, with dedicated rooms and facilities being kept available for H1N1 and dengue patients. Delhi’s Directorate General of Health Services has also issued guidance on infectioncontrol measures, including droplet precautions and the use of masks and protective equipment in isolation facilities.
Doctors say the current numbers do not warrant panic, but they do warrant greater awareness. “People should not become alarmed simply because the case count is rising. But they should also not ignore symptoms that are getting progressively worse. Early medical assessment is especially important for people who already have other health problems,” said Dr Prakhar Gupta, a physician at a Delhi hospital. For residents, the advice remains relatively simple: avoid close contact when unwell, cover coughs and sneezes, maintain hand hygiene and seek medical advice when symptoms are severe or persistent.
