Fever Screening with SATIR Thermal Imaging

Fever Screening for infection control


Why Fever Screening is needed?

In recent years, our world has gotten a lot smaller and more become accessible to people from all over the world. This is mainly due to advances in transportation technologies, such as aviation, becoming more affordable. This allows airlines to set up more travel routes than ever before.
With new airline routes and air fares becoming more affordable, more people travel the world than ever before. However, this can also pose risks to countries and their people as travellers can introduce new illnesses and viruses into the countries they visit.

In most cases, these illnesses and viruses cause a high body temperature, or a fever, which can be an indicator that a person is unwell and may need treatment. Fever screening is often sent up at border crossings, such as airports, and sea ports, and in public places, such as shopping centres and hospitals, to check people for a high fever which can sometimes be an indicator of serious illnesses such as Ebola, SARS or the Coronavirus. 

What is thermal imaging?

Thermal Imaging is the process to create an image using Infrared Radiation. Most things emit some form of Infrared Radiation, including humans and animals. Infrared Radiation is directly affected by temperature, e.g. the higher the temperature the more Infrared Radiation is emitted, and the inverse is also true. Using a Microbolometer, a thermal camera is capable of generating a Thermal Image by applying a colour palette to the different intensities of Infrared Radiation.

Why is thermal imaging used for Fever Screening?

Thermal imaging is used for fever screening and detection for a number of reasons. Often fever screening is set up at border points such as airports, seaports and in public places, these are busy areas often having hundreds of people passing at a time. If you used a regular ear thermometer on every single person that came off a flight or a ferry this can cause serious delays for passengers. Thermal Imaging cameras can solve this problem as they can be set-up to scan a large number of people at a time. It is also important to note when using a ear thermometer on every person the readings are at a single spot on the persons face , but a thermal image uses 1000’s of temperature readings (Pixels) to build up a 2 dimensional picture of the face of the person screen. This allows the medical team screening the person to have a better understanding of the temperature of the person. As with all fever screening the incubation period of the virus will affect the temperatures recorded on the human face .Any abnormal face temperature noted within the thermal screening process should then be checked further by medical professionals and further corrective action taken if required.
