Best at-home thermometers to track fever

 

With cases Covid-19 on the rise in the United States, you’re doing your part to watch for symptoms and flatten the curve. One of the major signs to look for is a fever, according to the Centers for Disease Control and Prevention (CDC). “Covid-19 usually starts with a low-grade fever (e.g., 99.5 degrees Fahrenheit),” says Luke Padwick, MD, emergency room physician and founder and CEO of Austin Emergency Centers.

Checking your own temperature at home can help you gauge your symptoms and decide whether to call a doctor or try to get tested. If you believe you have been exposed to Covid-19, the CDC recommends checking your own temperature twice a day, morning and night, for 14 days.

Thermometers have come a long way from mercury-encased-in-glass. Newer thermometers provide instant readings and often come with add-ons like cell phone apps and Bluetooth capability. (Due to the risk of breakage, mercury thermometers are no longer recommended, according to the American Academy of Pediatrics—AAP.)

The CDC recommends an age-appropriate thermometer, such as an ear thermometer, for infants and children under age four. You can also use a regular thermometer and place it at the center of the child’s armpit (the armpit method). Other body temperature measurement methods, aside from the mouth, include the forehead and the rectum. However, if you’re using the armpit method, the reading can be more than a degree lower than the actual measurement.

“A fever is your body’s normal response to fighting infection and means that your immune system is working properly,” says Georgine Nanos, MD, a board-certified family physician specializing in epidemiology and chief executive officer of Kind Health Group, a company offering aesthetic care in Encinitas, California. “The actual number is less concerning than the surrounding symptoms and cause.”

If your temperature is consistently above 99.5 degrees Fahrenheit, monitor for other symptoms, including body aches and pains, severe muscle aches and a dry cough, says Shahinaz Soliman, MD, a family physician and owner of Soliman Care Family Practice Center in Torrance, California.

Dr. Soliman adds, “If you have a combination of symptoms, call your primary care doctor if he/she is open and he/she will advise on the next steps.” However, if your primary care doctor is not available, she advises, call the emergency room before going there. “Usually I tell patients to stay home and rest for 14 days and if anything gets worse, to let me know. If their symptoms worsen, I have them come in and stay in the car and I go out to the car and do the test.”

As Covid-19 continues to spread, there is limited availability of at-home thermometers, and any online orders could be delayed. But, if you’re still in need of a thermometer, check out the following eight at-home thermometers for children and for adults that are all highly-rated; many are used by doctors themselves. Some of these may also be available at stores near you, so check availability.

Also, be sure to check out these at home Covid-19 tests that are on the horizon.

Ear thermometers use an infrared scanner to measure inside the ear canal, according to Nursing2020, a peer-reviewed journal. The Kinsa Smart Ear thermometer is a Food and Drug Administration-cleared thermometer that provides readings within one second in either degrees Fahrenheit or degrees Celsius. It features a Bluetooth connection to the Kinsa app with personalized guidance based on age, temperature, and symptoms. “Bluetooth features would be helpful if you need to maintain a digital record and this would also allow you to share this data with your doctor during a virtual or telemedicine visit,” explains Dr. Nanos.

“In infants and young children, the most reliable temp is in the rectum since they can’t usually cooperate with an oral thermometer,” explains Dr. Nanos. (While the AAP recommends measuring babies through toddlers up to age three through the rectum, you can start taking oral temperatures at age four). Try the Vicks baby rectal thermometer on littlest members of the family, which has a short tip that ensures gentle insertion and a 10-second read.
