The COVID-19 pandemic, otherwise known as the coronavirus, has been devastating our communities for months now. This virus is both serious and unprecedented, with over 1.58 million confirmed cases and 93,806 recorded deaths in the United States alone at the time of this writing. Someone infected with the virus, whether showing symptoms yet or not, could potentiallyinfect another 5 to 6 people before detection. Because of how contagious and transmittable this disease is, it is important to know how to spot symptoms and prevent further spreading, especially in places that have high foot traffic.

Although COVID-19 can come with many different symptoms, one of the most common tell-tale signs of the virus is a fever, with 83-99% of COVID-19 patients experiencing a fever at some point during their illness according to the CDC. A fever is characterized by elevated temperature in the body and can even cause brain damage, seizures, hallucinations, or death if the body’s temperature rises above 107.6 degrees Fahrenheit, or 42 degrees Celsius.

Fortunately, a fever is easily detectable thanks to modern technology, even at long distances and without a thermometer. With innovative companies coming out with thermal mass fever screeners for contactless fever screening, large groups of people can be screened for elevated body temperatures to help prevent further spread of the pandemic and keep businesses in line with CDC guidelines for businesses doing their part to slow the spread of the virus.

How Important is it to Screen for Fevers?

Because of how infectious the novel coronavirus is, screening for fever symptoms is one way for communities to reopen their business safely and still protect their employees and customers. A fever is the only COVID-19 symptom that can be measured externally while still maintaining social distancing requirements.

Businesses with high foot traffic would benefit greatly from screening for elevated body temperature because they are at higher risk for an infection outbreak. Businesses like airports, subway or train stations, hospitals and other medical buildings, large corporations, military bases, government buildings, shopping centers, schools, and package fulfilment centers are places that can experience large influxes of people who could bring in the COVID-19 virus and infect other customers or employees.

One of the biggest benefits of automated fever screeners is that they offer the opportunity for screening large numbers of people without any person-to-person contact. Using old fashioned thermometers to individually screen for fevers is not only inefficient and slows down business significantly but also simply is not a viable option for businesses that experience crowds of people like an airport. This opportunity offers for both efficiency and accurate crowd control without putting employees at risk for contact with infected individuals.

During this trying time, many essential employees are too scared to come to work because of the risk of infection and bringing it home to their families. The use of a mass fever screener might help ease the minds of employees and their employers during the reopening process. Although it will not be able to rule out all infected individuals, it may help prevent some from entering a business and causing a company outbreak. A fever screener paired with other virus prevention methods like cleaning frequently touched surfaces, social distancing and wearing face masks will help to prevent the spread of the virus while allowing for some semblance of returning to normal operations.

How Do Thermal Mass Fever Screeners Work?

A thermal mass fever screener, also referred to as an IR mass fever screener, uses infrared (IR) sensors and artificial intelligence technology to locate and pinpoint human faces and measure the skin’s temperature from a distance. In this way this technology helps support social distancing while still being able to quickly screen out potentially infected individuals by measuring elevated body temperatures.

Features included depends on the thermal screening system. Some include technology that ensures the highest accuracy possible for temperature detection such as the use of black bodies, learning algorithms and real-time calibration. Other beneficial features of a quality thermal screening system include adjustable temperature alarm thresholds, powerful data analysis software, and high-resolution image capabilities.

The benefit of systems that use black bodies to calibrate their equipment is greatly improved temperature-detection accuracy. A black body is a device which absorbs radiant energy of all wavelengths without reflecting that energy itself. What this does is ensures that any thermal radiation detected is related to temperatures only and eliminates interfering radiation from the environment. This device is crucial to reliable temperature readings.

High-tech infrared sensors are able to read thermal data at long range distances. This technology has been used by the military and law enforcement exclusively in the past but is now affordable and has been transformed into usable public sector devices to help with many situations, including thermal car cameras and thermal security cameras. Now infrared and thermal tech proves itself useful for fever detection and quick screening of big groups of people in the face of the coronavirus pandemic.

The Limitations of IR Mass Fever Screening

While mass fever screening can be beneficial to any business, it is important to keep in mind what it is used for and what it cannot do.

A thermal mass fever screener, or IR mass fever screener, is not designed to diagnose any virus or medical condition. However, it will detect elevated skin temperatures and add a layer of safety to screening for COVID-19 symptoms.

It has been reported in some recent studies that not all coronavirus-infected individuals will show symptoms, and it is important to realize that screening for fevers is not a guarantee that an infection or outbreak will not occur. These systems are efficient at what they do, but you should also keep with other virus prevention policies such as robust cleaning and disinfecting procedures, wearing facial masks and gloves, social distancing, frequent hand washing and turning away employees or customers who are sick or showing symptoms.

The specialty of mass fever screeners is quick, contactless fever screening to assist places of large foot traffic with limiting their exposure to sick individuals. A thermal fever screener will detect elevated skin temperature and is not a substitute for internal temperature detectors such as thermometers. Although an individual could have a high skin temperature for other reasons, it is safest to turn away those who might have a fever.

The official defining number for a fever may differ from state to state, so it is important to calibrate your fever screening system to detect your state’s minimum fever temperature reading. However, some companies have their own number for defining a fever, such as Walmart and Amazon defining a fever for their workers at 100- and 100.4-degrees Fahrenheit respectively. If you are buying a screening system for a large corporation, you may want to defer to their temperature threshold.
