Zimbabwe has rolled out a massive Polio vaccination campaign in the communities including hard-to-reach areas.
The vaccination campaign is targeting children under five regardless of their previous vaccination history.
More than 2.5 million children under five years of age are targeted in the first vaccination round.
The first round of vaccination will take place over the next four days (October 27 -30) with a second round planned for December.
Polio is a debilitating disease that can cause permanent disability and even death.
The country declared polio-free by the World Health Organisation in 2005, is yet to record its first case of wild polio virus since 1989.
The campaign is part of a comprehensive response to Polio outbreaks reported in Malawi and Mozambique recently.
Malawi, Mozambique, Tanzania and Zambia are also currently carrying out coordinated vaccination campaigns, with more than 40 million doses administered during the first three rounds of the exercise, following the detection of the first case of wild poliovirus in Malawi in 30 years.
