Severe shaking chills that last 20 minutes or that come and go over a 1-hour period. Chills occur before a temperature goes up. Take the temperature after the chills and shaking have stopped unless they continue for more than 1 hour. Take a temperature during the chills if they last for more than 1 hour.

Usually the person with this type of infection urinates in very small amounts. A person with a urinary tract infection feels a constant urge to pass urine even if little urine is in the bladder. No urine output for 24 hours. It is very important to report if the person you are caring for has not urinated in the last day or has urinated very little. This condition has a variety of causes and needs to be investigated.
