Schools centres are gathering places where children learn and play Some children may be too young to take proper personal care As such communicable diseases can easily spread through close person to person contact The source of infection can be children staff and parents Person to person contact may lead to cross infection i e the transmission of infective agents from one person to another For example a member of staff who fails to wash hands after caring for a sick child before making contact with another child he she may spread the infective agents from that child to the next child he she cares for 1 4 Principles of control of communicable diseases As mentioned above there are four factors crucial to the spread of communicable diseases They include the infective agent the source of infection the mode of transmission and the host Hence the control of the spread of communicable diseases should focus on controlling all these four factors so as to break the chain of infection Factors of A Control measures Infective agents e Disinfection to kill the infective agents Source of infection e Early detection isolation and treatment of patients e Removal of breeding sites Mode of transmission e Maintenance of good environmental personal and food hygiene e Adoption of infection control measures appropriate to the different modes of transmission Host e Building up personal immunity by susceptible population
