Two people, both from Hyderabad, have succumbed yesterday and presently 19 people are undergoing treatment for the disease, Swine Flu Co-ordinator at state-run Gandhi Hospital, Narasimhulu said.
In many cases, patients also suffered from other health problems like heart ailments and were referred to the hospital from private hospitals at a "last stage", he said.
Health officials here maintained that swine flu disease this year is not as virulent as it was in 2009, but high risk groups (those suffering from different serious ailments and low immunity) need to remain alert.
Last year, 11 people reportedly died of swine flu.
