Why You Need To Travel With A Thermometer: TSA Checking Temperatures
It's been almost two years since covid-19 struck the earth like a meteor. The travel industry has been dramatically and irrevocably altered with new rules for domestic and international travelers. The only thing we know for sure is that it will continue to change as we learn more about covid-19 and its affect on the well being of otherwise healthy humans. One of the most prevalent and emerging practices being implemented by businesses, US airports and governments, is the use of thermal body scanning to identify people with a fever who may be sick or about to be sick. Health protocols to prevent the spread of covid-19 in the United States vary from state to state and the same applies to other countries who have their own public health systems.
In South America, citizens are still wearing masks, social distancing and dealing with other covid restrictions from time to time. Most recently,on December 15, 2021, Peru announced that everyone must show proof of vaccination to board trains, enter hotels and even some restaurants. It's commonplace to have your temperature taken not only at the airport, but upon entry to archaeological sites incluging Machu Picchu, and even restaurants. Face shields are required on trains and public buses. (We've had reports that tinted face shields may not be accepted. It's best to go with transparent face shields.)
While having your temperature taken in an airport is not a big deal, what happens if you have a fever? Will you be allowed to board your flight? Are you at risk of being quarantined? Who covers the cost of delays and the expenses for medical treatment if needed? This is the reason travelers need to learn about fever and how it affects their body before they get to the airport. What is normal for you? What does a fever feel like? Should you suppress your fever with medication?
Why You Should Travel With Your Own Thermometer
It's best to check with your airline regarding their policies if you or someone you're traveling with presents with a fever on the day your flight departs. I couldn't find evidence of industry standards for when and how to take the body temperature, let alone what can, or should be done if it's elevated. Here's where having advance information about your temperature could save you time and possibly money if you're at risk of being delayed. Traveling with your own thermometer makes perfect sense. Add it to your travel kit with extra masks and sanitizers. And in Peru, you'll need a face shield for trains and buses, to be worn over your face mask.
In Peru, you can expect to have your temperature taken upon entry to pretty much everything including Machu Picchu. Usually a person holding a non-contact infrared thermometer will scan your wrist.
Can you get a covid test in Cusco before your flight back to the US or other country that may require it?
Yes. we have collected details about clinics, cost and logistics for getting this test. (follow this link here.) There's one really important thing to know. You need to be in and near Cusco the last 1-2 days before you fly home to allow time to get the test and the results before you travel to Lima. Can you get the test in Lima? Yes but you need to make an advance appointment online. Unless you're planning to spend at last a couple of days in Lima, I think it's easier to get the test in Cusco. But if you click that link I provided you will see contact links for the clinics in Cusco and the lab in Lima.
What you need to know about fever:
- 98.6F/38C is considered normal body temperature in a healthy adult, but can vary in individuals
- body temperature varies throughout the day and is typically lower in the morning and higher in the afternoon
- fever (elevated body temperature) may not stay at a constant temperature
- your body temperature can fluctuate according to your age, your gender, and even if you tell a lie! 97-99F is in the range of normal
- older people naturally have a lower body temperature due to aging and may run a fever without knowing it
- body temperature of 103F/39.4C or higher could be a sign of serious illness and you should contact your doctor or seek advice from a medical professional
- any signs of fever in infants or toddlers should be evalutated by a medical professional
- although parents will sometimes wait a day to two if fever is present in older children, its wise to seek medical advice immediatley if you have travel plans
What are some of the normal causes of fever:
- respiratory infections including flu and pneumonia
- viruses including covid-19
- physical injuries may have underlying infections
- childhood immunizations
- severe sunburn
- food poisoning
- spicy food (hot peppers can raise core temperature of the body)
- inflammatory conditions like rheumatoid arthritis
Guidelines for preparing to travel by air:
- before you travel, track your normal body temperature at different times of the day and under various circumstances, like being in a hot room or after drinking a hot beverage. (Some very creative high school students made Youtube videos to teach high school students how to fake a fever to get out of school. Exposing the business end of the digital thermometer to friction or hot water are some of the techniques. If you get a reading indicating you have a fever, check it again.)
- travel with a thermometer and take your temperature twice the day before you are scheduled to fly, and on the morning of your flight. Not all airports and airlines are mandating thermal scanning to determine if passengers have fever prior to boarding. But even if your airport is not among those who scan passengers for body temperature, you may have stopovers at other airports where the procedure is in place.
- does your travel insurance cover interruptions or delays due to fever/sickness on the day of travel? Read the fine print before you choose your policy.
- visit airport and airline websites to get advance information about how they plan to handle passengers who present with a fever or illness on the day of scheduled travel
- if you are denied boarding due to perceived illness, make sure you get written proof from the airline or authority, in case you plan to file a claim to recover your expenses.
How to take your temperature:
- old-fashioned "shake-down" thermometers contain mercury and I am guessing that they are prohibited on planes for that reason. The tube is made of glass and can be broken. I don't advise traveling with one of these implements.
- digital thermomenters measure body temperature by mouth, under the arm, or rectally. It may take up to a minute to get a reading. Temperatures taken under the armpit are the most convenient, but you need to know that the result is 1 degree F lower than if taken orally, and should be adjusted, (97F under the arm would be equivalent to 98F oral)
- no-contact thermal scanners are the same kind of devices used in public settings. Smart infrared technology gives an instant reading
Tracking our body temperatures is an easy skill for most people to master. Just like we learned how to wear face masks and wash our hands, we can learn how to monitor our body temperatures and use the information to prevent last minute delays and prepare for safe travel.

Personal Side Note:
People always ask me what my most useful travel gadget is. I've taken this simple looking sack, called the SCRUBBA, on many trips. You won't believe all the things I've used this for! It's a handy air-tight bag marketed for hand-washing laundry, but I turned it into a multi-use "tote-of-all-trades," with more functions than a swiss-army knife. Perfect gift for surfers, boaters, photographers or fisherpeople! (if you purchase the bag through the link on our website, I get a small commission for which I am truly grateful)
