We have come into the world of social distancing, thanks to the novel Coronavirus (COVID-19) that has restricted humans to come in close contact. The deadly virus seems to spread through touch ever since the outbreak of this fatal disease people across the world no matter its hospitals, airports, hotels, offices, malls, etc., have been advised to routinely check the body temperature of every soul before they enter the premises as one of the most common symptoms of Coronavirus includes fever, dry cough, and breathlessness. But with no-touch policy, it wouldn’t be possible to check the temperature with a mercury thermometer or a regular one unless it’s your personal very own thermometer. There is one way out to track the spread of this virus, possibly by maintaining the WHO guidelines of social distancing and using a non-contact infrared thermometer or forehead thermometer in areas with a high community gathering.
According to the FDA guidance,” fever is a common symptom of COVID-19, typically appearing 2-14 days after exposure and Telethermographic systems can determine surface skin temperature, which is then used to estimate the temperature at a reference body site. The available scientific literature supports the use of Telethermographic systems in the context of initial human temperature measurement during such a triage process caused dusting this pandemic.
After reading the FDA guidelines I researched about the Telethermographic system which is regarded as the non-contact thermography; thermographic that derives diagnostic indications from infrared images of the human body, so in simple words, the best way to measure body temperature through non-contact can be done through an infrared thermometer that could be put to this category of medical equipment. But there is a slight difference between a thermographic system and an infrared thermometer. Do read our section for a non-contact Infrared thermometer buying guide to clear your doubts.

What is a non contact Thermometer or an Infrared Thermometer ?
Let’s first understand how an Infrared thermometer works as compared to a regular thermometer. An infrared thermometer or a forehead thermometer helps reading an accurate reading of body temperature in less time using the infrared technology, scanning the temperature of the temporal artery present on the forehead. To check the temperature, you have to hold the thermometer a few centimeters away from the forehead and then slowly move it across the forehead, and it gives the reading within seconds. Being less invasive, these thermometers are ideal for babies, kids, or elderly and are most of the time accurate, just like an oral or rectal thermometer.
An infrared thermometer can even be used in various working environments or industries for checking the temperature of even an object from a distance. It can be used to check food temperature, electrical equipment, or any surface that you don’t want to touch and still wish to monitor the temperature. They are versatile than an ordinary thermometer.
Furthermore, an infrared thermometer is categorized into three different types based on their functionalities:
1. Contact Infrared Thermometer
Contact infrared thermometers give the best and most accurate reading b pressing the probe tip on the forehead or temple. These thermometers are good for personal use and in your own family when there is no risk of any infectious disease.
2. Non-Contact thermometer
A non-contact infrared thermometer is best for measuring the temperature from a safe distance. It can be scanned from 1 to 6 inches away from the forehead, thereby reducing the risks of infections. Right now during the COVID 19 outbreak these will be the best possible way to detect a person with a high temperature, but fever should not be the only option to put that person into an infectious person category, Further test is required but definitely, these thermometers can way them out to take precautions. This type of non-contact thermometer can even give you an accurate reading of an object, food, feeding bottles, or even rooms.
3. Multi-function or ear thermometer
A multifunctional thermometer, as the name suggests, gives accurate reading through the forehead, and ear as well. They are not recommended for newborn babies as while taking temperature as the probe has to be inserted in the ear canal, which gives the most accurate internal body temperature. Mostly these thermometers can be set on different modes as per need of different people.
Things to consider while buying the best non-contact Infrared Thermometers

A tip we can give for recording actual internal body temperature its recommend to add one degree to the recorded reading on your thermometer.
These thermometers are much safer than a contact infrared thermometer as there is no chance of any cross-contamination even when used on different people and require minimal disinfection. It also takes the temperature of a person in motion or moving. You must check for the distance ratio, like measuring the temperature from 1 to 6 inches away from the person or object.
