Children Without Worms is a public-private partnership between The Task Force for Global Health and Johnson & Johnson, who donated the mebendazole medication. Intestinal helminths are a major problem in Nicaragua with 73% of rural households lacking clean drinking water and 73% lacking sanitation. Since 2009, drug donations from Johnson & Johnson have enabled annual deworming of school-aged children and medication supplied by other NGOs has enabled deworming of pre-school children, although questions were raised as to whether the frequency should have been increased. In 2007, Burundi undertook a parasitological survey across its population which demonstrated that intestinal schistosomiasis was highly focalised in areas close to water and soil-transmitted helminthiases, including hook worm, was more widely distributed amongst its people. The report demonstrated the suitability of a mass drug administration for the entire population. The Schistosomiasis Control Initiative had developed an approach which would cost 50 US cents per person per year, and was piloted in Burundi and Rwanda in 2007 with a $9million investment from the Legatum Foundation, along with support from various other government donors, philanthropists and pharmaceutical companies, over a four-year period. The Philippines Soil Transmitted Helminth Control Program is run by the Department of Health and implemented by the Department of Education in the Philippines. It is a partnership with the WHO, University of the Philippines Manila, UNICEF, World Vision International, Feed the Children, Helen Keller International, Plan International and Save the Children. It involves giving all children doses of Albendazole or Mebendazole. However, in 2013 the Director of the National Institute of Health in the Philippines questioned the effectiveness of the programme because it only covered only 20% of affected children with an infection rate of 44%. By 2015, 16 million children were targeted in the deworming programme. with some media claims that some of the medication was found to be expired. Government officials later denied this. Other national press reports in July 2015 stated that a small number of children had been admitted to hospital due to an "adverse effect" of the deworming medication. Successful deworming and positive health outcomes were also achieved by the Essential Health Care Program implemented by the Department of Education in the Philippines. This national programme includes giving school children deworming drugs twice a year, as well as group handwashing with soap and brushing teeth daily with fluoride toothpaste as a group activity at set times of the day at the school premises.
