Infrared or no-contact thermometers are just as accurate as oral or rectal thermometers when used appropriately, according to research. However, with many places now demanding temperature checks, these hand-held thermometers are proving to be safe, rapid, and accurate, while also aiding in the reduction of coronavirus spread. Oral and rectal thermometers need to be kept clean by washing them with soap and water after each use. In addition to health care professionals, parents can use infrared thermometers to check their children's temperatures. These devices work by measuring the temperature of an object (such as the tip of a child's nose or back of the hand) through its own heat signature. This method does not involve touching the child directly, which can lead to transmission of bacteria from one person to another. Infrared thermometers can be found at drugstores and grocery stores for $20-$100; they work by channeling infrared energy emitted by your body into a sensor that displays your temperature. You can use this information to guide treatment decisions during a fever. Parents should check their children's temperatures regularly, especially if they have a history of fevers. Using an infrared thermometer allows for rapid, noninvasive testing without putting anyone at risk of infection. Children with elevated temperatures may experience other symptoms, such as headache, cough, sore throat, runny nose, and muscle aches.
