Patients should be closely monitored for the initial signs of shock. The critical period is during the transition from the febrile to the afebrile stage and usually occurs after the third day of illness. Sometimes serial haematocrit determinations are essential to guide treatment plan, since they reflect the degree of plasma leakage and need for intravenous administration of fluids. Haematocrit should be determined daily specially from the third day until the temperature remains normal for one or two days.
