Coronavirus (COVID-19)
fever screening solutions

Fever screening solution using FLIR A320 infrared thermal cameras

Viral and bacterial infections such as the Coronavirus (COVID-19) spread mainly from person to person and contact with infected objects and surfaces. This highly contagious virus has now become a pandemic as shown by the recent flu outbreaks.

In efforts to contain the highly contagious virus, thermal cameras are set up at checkpoints or hand-held at airports, borders, and entrances to businesses, schools, and other institutions. These devices are being used to screen large numbers of people for elevated body temperatures quickly and reliably.

FLIR has received FDA 510(k) approval for its thermal imaging and temperature screening products.

Detecting Coronavirus fevers quickly and reliably with the FLIR A320

The FLIR A320 infrared thermal imaging camera can visualise, quantify and screen differences in skin surface temperature changes. This device is being used to detect people with fever-like symptoms that may be the highly contagious Coronavirus (COVID-19).

The FLIR A320 Tempscreen solution is a vital tool to help detect and minimise the spread of the highly contagious Coronavirus.

Q&As: FLIR products and Coronavirus screening

  • While FLIR thermal cameras may indicate if someone has a higher-than-average skin surface temperature, thermal imaging cannot detect or diagnose infection. The screening procedures implemented at airports are just the first step when it comes to screening for a possible infection: it’s a quick way to spot anyone who might have an elevated temperature that might indicate illness, but they must always be followed up with further screening before authorities decide to quarantine a person.

  • FLIR thermal cameras are a great tool that can be used to detect variations of surface temperatures but are not intended to diagnose or detect specific medical conditions such as viruses or other illnesses. 

  • Every object or person emits heat (infrared radiation). FLIR thermal cameras detect this emitted radiation and can use it to identify the surface temperature.

  • With this capability, FLIR cameras are commonly used as a non-contact screening tool to detect differences in skin surface temperatures and pattern changes. In fact, FLIR has received US FDA approval for using a variety of its thermal camera products to screen high traffic public places like airports, train stations and subway stations. 
  • Customers use FLIR handheld cameras, FLIR cameras that can be mounted on tripods, or FLIR fixed-mounted cameras as a non-contact screening tool to detect differences in skin surface temperatures and temperature pattern changes.

  • As people walk by the camera, the camera can not only “see” or detect these temperature differences, but radiometric cameras can provide a temperature measurement. Camera operators look for temperature anomalies and if they notice a higher temperature or abnormally high thermal reading, the operator could request to screen that person further using other medical screening techniques.

  • For this specific application, FLIR utilises our calibrated thermal imaging cameras. With these models, the operator will be able to view temperatures in degrees C or degrees F, using various analytical tools, like a spotmeter or region of interest.

  • In order to obtain a good temperature reading, it is recommended that the intended target be as close to the camera as possible. In this use case, we would make recommendations based on the location of the camera.  If the operator wanted to place the camera in a remote location, we would most likely recommend a telephoto lens.  Therefore, distance to the target is an important consideration, as is Focus. 

  • It is extremely important that the application be set up so that all of the intended targets to screen would be in perfect focus.

  • FLIR has been manufacturing thermal imaging cameras since the late 50’s (AGA) and the implementation of technology has been widely used in thousands of applications.

  • For Elevated Body Temperature screening, we witnessed an increase during the first potential epidemic with SARS in 2003 and then in 2009 with the H1N1 outbreak.

  • The temperature measurement cameras we have been discussing in this piece have been calibrated to an accuracy of +/- 2 degrees C or 2% of the temperature reading at 30 degrees C ambient environment. FLIR uses calibration standards established under  NIST (National Institute of Standards and Technology) traceable black body reference sources.

  • Note, there are many contributing factors that affect accuracy. I mention in the previous questions, that FOCUS and DISTANCE can affect accuracy.  Other factors, like the emissivity of the target, ambient environment, and speed at which the temperatures are acquired all play a pivotal role in accuracy.

  • It is highly recommended that operators and users obtain thermal imaging training. There are many levels of certification.  For example, an operator can be trained to Level 1, 2, and 3 certifications.

  • The corner of the eye is most accurate place on outside of human’s body.

FLIR infrared cameras help detect the spreading of swine flu and other viral diseases

Several major airports in Asia discovered the benefit of infrared cameras in conjunction with the outbreak of SARS a couple of years ago. They now use FLIR infrared cameras to scan whether arriving travellers can be contaminated with the ´N1H1 virus – the correct name of the virus behind the Swine Flu.

Detecting A H1N1 in Tocumen International Airport in Panama

During the SARS (Severe Acute Respiratory Syndrome) epidemic, IR cameras first began to be used in several international airports. The mistakes made during this first phase of implementation have yielded many valuable lessons. Although detecting fever with an IR camera is a viable technique, certain procedures must be consistently followed to obtain a reliable temperature measurement.
