Study information and requirements were sent to each centre for their further consideration and permission to conduct the focus groups. This sampling approach sought participants who worked in a variety of settings and who could contribute their experiences on managing enteric outbreaks. Centres and staff members were defined as those who provided daytime care for an entire day to a group of children (e.g. did not include those who provided only after-school care), and whose staff's first language was English. Participating staff had daily direct contact with the children and had worked in a centre for more than six months.
