Pneumonia is the single largest cause of death in children less than 5 years old and these are preventable deaths.[1,2] It is also an important cause of morbidity , especially when it is recurrent or severe as it may be linked with future adult lung disease.[3] Determining the aetiology of pneumonia is difficult in children who cannot produce satisfactory sputum for culture. Hence the reliance on molecular methods like polymerase chain reaction (PCR) and Enzyme immunoassays(EIA) looking at serological rise to determine the true aetiology of pneumonia is important especially in the era where mixed infections are common and may be associated with severe infections.
