(a) The number of polio cases reported in the country during the calendar year 2009 and 2010,
State/UTwise and Union Territory-wise is given at Annexure.
(b) Convergence of a number of risk factors such as low routine immunization coverage, poor
environmental sanitation, higher incidence of acute diarrhorial disease etc favour virus
transmission and interfere with effectiveness of oral polio vaccine.
(c) 33 out of 35 States / UTs are free from indigenous polio virus circulation. Indigenous
transmission of polio is limited to high risk areas of UP and Bihar. Only one genetic cluster
is presently in circulation as compared to 9 in 2006. However as long as poliovirus
transmission continues in any part of the country, children under five years of age are
vulnerable to getting the disease.

country :-
# Two national Immunization Days (NIDs) are conducted every year in which 172 million children
upto the age of 5 years are vaccinated.
# Sub National Immunization Days (SNIDs) are conducted 5 to 7 times in a year in UP, Bihar,
Delhi, Mumbai and other areas to cover high risk / migratory population.
# During the campaigns,children at bus stands, market places, major congregation points,
railway stations and moving trains are vaccinated to immunize the population on move.
# New born tracking is done to vaccinate them during the polio campaigns.
# Mop Up rounds are conducted in and around the area where a polio case is detected.
# Special plan has been chalked out to vaccinate children in high risk areas of Kosi Riverine
Belt.
