Kindergarten environment and being in a group are ideal factors for the spread of viruses and bacteria, and therefore various infectious diseases. Regardless of whether it is a large number of children in a small space, insufficient ventilation of the rooms or objects that children share with each other, one thing is certain - infection is difficult to avoid, but it is still possible to act to strengthen prevention by following prescribed guidelines and protocols. The most common infectious diseases of children of early and preschool age include streptococcal angina, chicken pox, head lice, scarlet fever, fifth disease, salmonellosis and enteroviruses, and their causative agents can be bacteria, viruses or parasites. Croatia, like other countries, implements an active immunization program that prescribes mandatory vaccination against ten infectious diseases. Infectious diseases in themselves have always been a challenge in kindergartens, therefore there is a visible need for highly educated nurses as well as highly educated educators who will have the knowledge, skills and ambitions to follow and improve guidelines and protocols for the control of children's infectious diseases. Communication between parents and educators plays an important role in prevention, as well as education conducted by the health manager on the importance of maintaining proper hygiene and adopting healthy lifestyle habits. Due to the high frequency of childhood infectious diseases, the aim of this research was to gain insight into the understanding of experiences and perceptions of educators about infectious diseases in kindergartens through their socio-epidemiological characteristics, the epidemiology of infectious diseases in their kindergartens, and through parents' attitudes towards childhood infectious diseases. The obtained results are mainly based on presenting the issue of children's infectious diseases, and the biggest challenge they cite is bringing a sick child to kindergarten and poor cooperation with local health institutions. They emphasize the importance of communication and education and share a positive attitude towards changes at the level of public health in terms of improving children's health care. In the Republic of Croatia, the employment of health care managers is still a problem. With a larger number of health care managers, i.e. with highly educated medical staff such as bachelors and masters of nursing, would achieve better health care of children since one of the roles of the health care manager is the health education of parents and children with the aim of acquiring proper hygiene habits and adopting a healthy lifestyle.
