This pocket book contains up-to-date clinical guidelines, based on available published evidence by subject experts, for both inpatient and outpatient care in small hospitals where basic laboratory facilities and essential drugs and inexpensive medicines are available. It is for use by doctors, senior nurses and other senior health workers who are responsible for the care of young children at the first referral level in developing countries. In some settings, these guidelines can be used in the larger health centres where a small number of sick children can be admitted for inpatient care.
