The patients were mostly children below the age of 10 years.

Nine positive patients were admitted to Lakeside Hospital. Among them were four adults and five children. Interestingly, only one patient had travelled abroad.

The 40-year-old US citizen of Indian origin had returned from the United States on July 26 and developed the symptoms.

“I think the rest seven patients must have got H1N1 influenza from their schools,” said the Hospital’s resident medical officer, Dr Raviraj. All the patients are stable.

Seventy-five suspected cases were screened and 46 throat swab samples were collected at the Rajiv Gandhi Institute of Chest Diseases (RGICD) on Saturday. 

The patients were categorised as A, B and C where A meant the higher risk groups of children, senior citizens and patient with severe symptoms, B   for mild symptoms and C for patients who came out of curiosity. 

Twenty six cases were categorised under  group A.

Meanwhile, three patients were admitted to Manipal Hospital including a 59-year-old lady, who was shifted to the ICU. Only one positive case is currently at the St John’s Hospital.
