New Delhi/Pune, Aug 3 - India reported its first swine flu death Monday when a 14-year-old girl succumbed to the influenza A (H1N1) virus in Pune. The girl was suffering from the flu for over a fortnight and her death was caused due to 'delayed treatment', health officials said.

Confirming news of the death, union Health Secretary Naresh Dayal said in New Delhi that the girl was given anti-flu medicine at a very late stage.

'It appears she was treated late. If she would have been treated earlier, she could have been saved,' Dayal told a news channel.

'It is a matter of concern,' he added.

'The deceased patient, Riya Shaikh, had been admitted to Jehangir Hospital, a private hospital, July 21. As per preliminary information, she passed away this evening,' a health official in Pune told IANS.

Pune, which had already become the country's swine-flu capital, notched 102 patients Monday, of whom 86 are children, mostly school students, he said.

The girl had consulted a general practitioner when she first reported flu-like symptoms - sore throat, runny nose, headache - on July 21. When her condition improved, she joined school on July 23.

'She again developed fever on July 25, for which she consulted another private practitioner. Her fever continued and she was admitted to a private nursing home in Pune July 27,' according to a health ministry statement.

Her condition worsened and she was shifted to the ICU and put on the ventilator on July 29. 'The patient's lung aspirate was sent to the NIV (National Institute of Virology) on July 31 and was tested positive for swine flu.'

She was put on Oseltamivir or Tamiflu on July 30. 'Her condition deteriorated again with multi-system involvement and she expired on the evening of August 3,' the statement said.

Health officials are flummoxed how a serious patient of H1N1 could remain under treatment in a private hospital and are inquiring whether the case was notified to the authorities or not, especially since Pune had been declared a 'pandemic' city last month.

The health ministry said the hospital staff, including three doctors and a nurse, who had treated the girl and had developed respiratory symptoms were being treated with Oseltamivir.

'About 85 other hospital contacts have been put on prophylaxis, while 31 contacts, including 11 family contacts, have also been put on chemoprophylaxis,' it added.

Dayal said 558 confirmed swine flu cases have been reported in the country so far, of which 470 people have been discharged from hospital, while the rest are being treated

in identified health facilities.
