North India has been worst hit by influenza (A) H1N1 or swine flu this year, with at least 61% cases reported from across the country coming from Rajasthan, Delhi, Haryana and Punjab.

According to surveillance data collected under the government’s Integrated Diseases Surveillance Programme (IDSP), the week between January 28 and February 3 this year was particularly bad as 1,176 of the 2,101 cases that tested positive during this period were from the four north Indian states.

Again, of a total of 6,701 cases, as many as 4,114 were reported from these states with Rajasthan reporting 2,363 cases, Delhi 1,011, Haryana 490 and Punjab 250 cases. Of 226 swine flu deaths, 117 were reported from three of these states, except Delhi that has officially reported no death.

Experts have, however, warned against creating panic, saying this was a cyclic phenomenon.

“Flu cases are either due to influenza (A) H1N1, H3N2 or influenza B. There will always be a strain or a combination of strains that is more prevalent than the other and cause infection. There’s largely immunity within the community against the strains but whenever there is a build-up of people who aren’t exposed to the prevalent strain, infections will go up,” said an expert in a government laboratory requesting anonymity as the expert is not authorized to speak to the media.
