“…There was an overall prevalence of 7.9% fever in our evaluation, which is similar to the prevalence of febrile subjects for an outpatient setting in other studies. 17,26,27 The Omnisense ITDS had a very high sensitivity, comparable or superior to recent studies. 13,26,28,29 Importantly, all of the false negative cases had low grade fever not greater than 37.8 C, suggesting that false negatives were mainly confined to low grade pyrexia.…”

“…IR thermography-also known as thermal imaging-is a non-contact and noninvasive imaging approach that has been exploited for a wide range of biomedical and non-biomedical applications. It has been studied for use in cancer imaging [1][2][3][4][5][6][7], ischemic monitoring and vascular disease [8,9], wound assessment [10], corneal temperature measurement [11][12][13], diagnosis of rheumatologic diseases [14], fever screening [15][16][17][18][19][20][21][22][23][24][25][26] been encountered in clinical translation of IR thermography. Standardization in different aspects of medical thermography, including tools (both acquisition hardware and processing algorithm) and examination environment, has always been a general agreement among the community of medical thermography [27].…”

Infrared (IR) modalities represent the only currently viable mass fever screening approaches for outbreaks of infectious disease pandemics such as Ebola virus disease and severe acute respiratory syndrome. Non-contact IR thermometers (NCITs) and IR thermographs (IRTs) have been used for fever screening in public areas such as airports. While NCITs remain a more popular choice than IRTs, there has been increasing evidences in the literature that IRTs can provide great accuracy in estimating body temperature if qualified systems are used and appropriate procedures are consistently applied. In this study, we addressed the issue of IRT qualification by implementing and evaluating a battery of test methods for objective, quantitative assessment of IRT performance based on a recent international standard (IEC 80601-2-59). We tested two commercial IRTs to evaluate their stability and drift, image uniformity, minimum resolvable temperature difference, and radiometric temperature laboratory accuracy. Based on these tests, we illustrated how experimental and data processing procedures could affect results, and suggested methods for clarifying and optimizing test methods. Overall, the insights into thermograph standardization and acquisition methods provided by this study may improve the utility of IR thermography and aid in comparing IRT performance, thus improving the potential for producing high quality disease pandemic countermeasures.

“…1. TI is widely used in medical settings such as cancer research (Head and Elliot, 1995) and fever screening (Hewlett et al, 2011) to detect and locate thermal abnormalities characterized by an increase or decrease found at the skin surface (Hildebrandt et al, 2010). Selfe et al (2006) and Kennet et al (2007) have previously highlighted the effectiveness and the reliability of the use of TI to measure Tsk.…”

a b s t r a c tBackground: Cryotherapy is used in various clinical and sporting settings to reduce odema, decrease nerve conduction velocity, decrease tissue metabolism and to facilitate recovery after exercise induced muscle damage. The basic premise of cryotherapy is to cool tissue temperature and various modalities of cryotherapy such as whole body cryotherapy, cold spray, cryotherapy cuffs, frozen peas, cold water immersion, ice, and cold packs are currently being used to achieve this. However, despite its widespread use, little is known regarding the effectiveness of different cryotherapy modalities to reduce skin temperature. Objectives: To provide a synopsis of the use of thermal imaging as a method of assessing skin temperature following cryotherapy and to report the magnitude of skin temperature reductions associated with various modalities of cooling. Design: Structured narrative review. Methods: Three electronic databases were searched using keywords and MESH headings related to the use of thermal imaging in the assessment of skin temperature following cryotherapy. A hand-search of reference lists and relevant journals and text books complemented the electronic search. Summary: Nineteen studies met the inclusion criteria. A skin temperature reduction of 5-15 1C, in accordance with the recent PRICE (Protection, Rest, Ice, Compression and Elevation) guidelines, were achieved using cold air, ice massage, crushed ice, cryotherapy cuffs, ice pack, and cold water immersion. There is evidence supporting the use and effectiveness of thermal imaging in order to access skin temperature following the application of cryotherapy. Conclusions: Thermal imaging is a safe and non-invasive method of collecting skin temperature. Although further research is required, in terms of structuring specific guidelines and protocols, thermal imaging appears to be an accurate and reliable method of collecting skin temperature data following cryotherapy. Currently there is ambiguity regarding the optimal skin temperature reductions in a medical or sporting setting. However, this review highlights the ability of several different modalities of cryotherapy to reduce skin temperature.

Evaluation of an Infrared Thermal Detection System for Fever Recognition during the H1N1 Influenza Pandemic

Abstract: Infrared thermal detection systems (ITDSs) have been utilized in several countries to screen for fever in travelers. Since fever screening with an ITDS is rapid and noninvasive, this technology may be useful as an infection control measure in clinical settings during a pandemic.
