The IMCI chart booklet is for use by doctors, nurses and other health professionals who see young infants and children less than five years old. It facilitates the use of the IMCI case management process in practice and describes a series of all the case management steps in a form of IMCI charts. These charts show the sequence of steps and provide information for performing them. The IMCI chart booklet should be used by all health professionals providing care to sick children to help them apply the IMCI case management guidelines. Health professionals should always use the chart booklet for easy reference.The chart booklet is divided into two main parts because clinical signs in sick young infants and older children are somewhat different and because case management procedures also differ between these age groups. Sick child aged 2 months to 5 years This part contains all the necessary clinical algorithms, information and instructions on how to provide care to sick children aged 2 months to 5 years. Sick young infant aged up to 2 months This part includes case management clinical algorithms for the care of a young infant aged up to 2 months. Each of these parts contains IMCI charts corresponding to the main steps of the IMCI case management process.
