The state has been recording the second highest incidence of the disease in India for the last few years.
'Sixteen cases of P1 in Bihar as against only three last year is certainly a cause for concern. But we believe that things will be under control soon,' Kapur added.
WHO authorities in New Delhi said that though there are some implementation problems at the ground level, India is on the right track.
Bihar recorded over 300 new polio cases in 2008 but in last eight months there are just 49 cases. The state recorded 61 polio cases in 2006 and 193 cases in 2007.
'India is on the right track of polio eradication and you will see the outcome soon,' a WHO official added.
Both WHO and Rotary praised the central government for taking extra care to get rid of the disabling disease. Last week, the central government sanctioned over Rs.32 billion to wipe out the disease from the country in the next three years.
After a recent Cabinet Committee on Economic Affairs meeting, Home Minister P. Chidambaram said that the main objective is to achieve the 'goal of zero transmission of polio and obtaining international polio free certification for accomplishment of this goal'.
