Infections refer to the introduction into the body of microbes or infectious agents (viruses, bacteria, parasites or fungi) that can multiply and cause injury or disease. A person can be infected and have no symptoms, even though they may be contagious. Infectious diseases, such as streptococcal infections and pediculosis (lice), result from a disruption in the normal function of the body due to invasion by an infectious agent. They manifest through a variety of signs and symptoms.
Infection-related interventions in schools should aim to prevent infections and infectious diseases through:
basic hygiene, such as for colds or gastroenteritis
vaccination, in the case of measles or meningitis

Specific recommendations
Dispel myths about hygiene, especially about lice. Pediculosis is:
common and often asymptomatic
not a sign of uncleanliness
not a vector for the transmission of serious diseases
