In infants, oral and anal temperature measurements are generally more accurate, but it is easier to routinely measure temperature in the axilla. In infants or children in the process of growth and development of fever is more common, so you need to pay attention to the child’s temperature measurement, the general routine measurement is to use a mercury thermometer to measure the temperature of the armpits, relatively accurate and easy. But more accurate is to measure the temperature of the body, you can use oral and intra-anal measurement. Oral and intra-anal measurements are not well adapted to babies, and are likely to be less cooperative, affecting the results, so it is generally recommended to measure the temperature in the armpits.
