At a cross-border meeting between Nigeria and Niger Republic yesterday, the Executive Secretary of National Primary Health Care Development Agency (NPHCDA) Dr. Ado Jumada Mohammad, said a significant percentage of polio cases emanates from border communities.

Nigeria is among the three nations still struggling to check the transmission of polio virus with states in the northern parts of the country regarded as the most endemic.

He said emphasis would hence forth be placeon the border areas.

Mohammad said the federal government had introduced special intervention programme targeted at the border areas so as to curb the spread transmission of the disease, noting that border areas still remained the key challenge.

The NPHCDA boss disclosed that part of the measures taken to address the incidence at the border areas was the stationing of vaccinators for 24 hours at the border areas to vaccinate people coming in and going out of the country.

"We will work on intensifying border synchronization activities and all the houses along the border will be thoroughly immunized" he enthused.
