Materials most urgently needed would befor shelters, such as tarps, bamboo and rope. * A stock of high-energy biscuits will only last two weeks.Rice supplies for both the refugees who crossed the border lastyear as well as this year's arrivals "may be problematic". * There is enough safe water available to supply 2,500people for 72 hours with additional stocks in the pipeline. * Safe sanitation and hygiene can be provided for 500 peoplewith an additional 1,000 kits available. There are 400 emergencylatrine chambers with 60 more under construction. * Overcrowded camps and a lack of knowledge of availablemedical facilities hamper the mobility of women in labour orthose experiencing an emergency. * Vaccination for children under five has started at theKutupalong settlement area with 285 children vaccinated for oralpolio, measles, rubella and given vitamin A shots. * There is a need for segregated space in makeshiftsettlements, active community watch groups and stable powersupplies at night to increase safety for women and reduce thethreats of violence against them. * Many children have been found without clothes and are atrisk of abuse and trafficking.
