Authorities in Papua New Guinea are preparing for the second round of a vaccination campaign that's trying to again rid the country of polio.
More than 3.5 million children will be targeted for immunisation in the latest round.
Since an outbreak was confirmed last June, 26 cases of polio have been found in nine provinces. One of them, a 9-month-old boy, has died.
The World Health Organisation said the last immunisation campaign managed to get 95 percent of all under 15-year-olds vaccinated.
But coverage is still suboptimal in some provinces - particularly New Ireland, which only got 72 percent of children immunised, it said.
The latest campaign will kick off next week and the authorities are urging everyone to take their child for the drops, saying it is the only way to stop the outbreak.
