The most causative agent of pharyngitis is viral and the second is a bacterial infection. Prescribing antibiotics without confirming the source of infection is not recommended and should not be applied in that case. Our results involved 150 children with sore throats and fever. A novel rapid chromatography immunoassay kit (Group A Streptococcus diagnostic, USA) was used to detect Streptococcus pyogenes antigen in the samples. FDA approved the equipment as a quick test to differentiate between viral and streptococcus pharyngitis. Data showed that 60 (40%) of patients were positive for GAS, while 90 (60%) were negative. The current study spots light on the pharyngitis caused by Streptococcus type A to prevent or minimise the inappropriate prescribing of antibiotics.
