If a thermometer is not available, check for the presence of a fever by placing a hand on an individual's forehead and gauging whether the skin is hotter to the touch than usual, as stated by Choose Well, a branch of NHS. Also look for flushed skin, shivering and other signs that a fever is present, like loss of appetite or fatigue. Keep an eye out, and if the fever persists or worsens, seek medical attention immediately.
If the fever persists, get a thermometer to obtain a more accurate reading of the temperature of the fever, as this will determine whether to seek medical attention. An individual with a fever below 100.4 degrees Fahrenheit can still receive medical care in the comfort of his or her own home; however, if the fever rises to above 101.3 degrees F, contact a physician immediately to determine how to proceed. A fever that is above 104 degrees F requires immediate medical attention. The individual must go to an emergency room.
When caring for an individual with a fever at home, make sure that the room temperature is comfortable, and that plenty of water is provided. It is crucial to prevent dehydration at this point.
