-Insanitary environment:poor housing,slum areas,with high crowdness index,crowded badly ventilated classrooms.bedroos and other confined places,faulty habits that favour spred of infection
-Frequent exposure to streptococcal pharyngitis since causative organism has a big number of serptypes.
-Cases of sterptococcal pharyngitis not or improperly given chemotheraphy.
-Host factors:poor living conditions,inheritance.
-sudden onset of fever,anorexia,epistaxis and precordial and abdominal pain.

-health promotion,including adequate nutrition.
2.Prevention of streptococcal infection,specially in confined groups of children and adolescents,in schools,institutes and camps.
