Nunavut has recorded 15 new swine flu infections in the past two weeks, prompting health officials to warn that a second H1N1 flu wave is likely beginning.

The territory's Health Department is strongly encouraging anyone who has not already received the H1N1 flu shot to get it now, according to a public health advisory sent Tuesday.

While the vaccine was offered to all of Nunavut's 25 communities during a territory-wide immunization campaign last month, it is still available at local health centres, including the public health clinic in Iqaluit.

Health officials are especially urging pregnant women and people with chronic health conditions to make sure they are vaccinated, since they are at a a greater risk of getting sick.

More than 500 mostly mild cases of swine flu were confirmed in Nunavut during the first outbreak, which started in late May and continued through the summer. A pregnant woman died of the virus in July.
