'We've taken a decision to have a clinical audit on Monday. During our earlier survey, we found that 40 percent of the swine flu victims had co-morbid factors (pre-existing illness) and many died due to late admission. However, the audit will give a clear picture of the actual cause for deaths,' she added.

The profile of each victim, which includes name, age, sex, symptoms and cause of death, will be studied by a panel of experts during the clinical audit.

Of Tuesday's 324 new cases, the national capital recorded as many as 108 cases.

According to Delhi Health Minister Kiran Walia, 2,065 people have so far been admitted and treated in Delhi government hospitals. 'More than 90 percent of these patients have been successfully treated and discharged,' she said.

As many as 1,018 children have been treated for influenza A (H1N1).

The Delhi government, meanwhile, also announced that Tamiflu, the anti-influenza medicine, will be sold at authorised retail chemists. The central government had last week allowed 'restricted sale' of Tamiflu through over 500 chemists.

The decision to alow Tamiflu sales was taken during a meeting held by Walia after the state government received notification from the central government.

'The government has implemented the notification of the Indian government to allow sale of Tamiflu at the authorized outlets of authorized Schedule 'X' chemists in the capital to facilitate the patients of swine flu as well as to curb the swine flu epidemic,' Walia said.

Swine flu cases were also detected in Maharashtra (67), Tamil Nadu (43), Andhra Pradesh (28), Karnataka (20), Gujarat (2) and Haryana (1).
