oa Current Allergy & Clinical Immunology - The immune system : PID123

Volume 28, Issue 1

Nomhle Shongwe is concerned because her 3 year old son, Anathi, has been experiencing recurrent infections. He has been treated for pneumonia twice in the past year. She consults Dr Goodheart, a paediatrician at the district hospital, who has an interest in infectious diseases and immunology. Dr Goodheart explains to Nomhle that healthy young children may easily experience six to eight upper respiratory tract infections per year, and even more if they attend a child care facility. Infections that occur more frequently than this, especially if they are caused by specific germs (microbes), or if they are deep seated (as in Anathi's case) may give a hint that the immune system is not functioning normally.
