Three steps are required for the transmission of an infectious disease from one individual to another:

  • The pathogen must be excreted by the person who is ill or the asymptomatic carrier (by decreasing frequency order: nose, oral cavity, stools, skin, urine)
  • The pathogen should be communicated to the healthy person (by order to frequency: aerosol, direct or indirect contact through objects or another person)
  • The pathogen must reach a susceptible site (oral cavity, nose, eye)

 

Communities of children (school, nurseries and infant day care, drop-ins), resulting in close contacts between a number of children in a relatively limited space promote the transmission of infectious agents.

The transmission of viruses, bacteria, and parasites from sick subjects or asymptomatic carriers to healthy subjects occurs through nasal and oral secretions (sputters), stools, urine or skin (direct or indirect contact with objects or another person).

Communities of children (school, nurseries and infant day care, drop-ins), resulting in close contacts between a number of children in a relatively limited space promote the transmission of infectious agents.

Day care nurseries are particularly concerned because of:

  • Promiscuity and gregariousness of this type of child care
  • The immature immune defence systems of infants with a longer and more frequent carriage of pathogens
  • Factors specific to early childhood (incontinence, suction of hands and objects, dependence to adults providing multiple care)

Every child carries viruses, bacteria, and parasites, which can be passed to the other children of the nursery, and also to staff and members of their own families.

A number of factors related to early childhood (incontinence, suction of hands and objects, dependence to adults providing multiple care) also promote the transmission of infectious diseases.

All this explains why the incidence of respiratory infectious diseases is higher in children living in nurseries.
