Abstract Background CDC and icddr,b are conducting an acute febrile illness (AFI) research project in four hospitals in Bangladesh. Enrolled subjects have measured fever of ≥100.4°F. To determine the most-sensitive temperature measurement method, we collected multiple measurements on patients with fever history between March and April 2019. Methods Patients were screened in outpatient departments of four hospitals in Bangladesh between March 7 and April 15, 2019. Screening used at least two of three methods: tympanic, oral, or axillary. Records were consolidated using Microsoft Excel and analyzed in R3.4.3. We examined the correlation between temperatures measured by different methods for each patient. For records with all three measures, we calculated the likelihood of meeting AFI inclusion criterion of ≥100.4°F (38°C) by measurement method. Results 3,060 subjects were enrolled. The highest correlation among measurements was between axillary and oral (r = 0.882, 95% CI 0.868–0.895). The lowest correlation was between tympanic and oral (r = 0.71, 95% CI 0.69–0.73). Axillary and oral had the highest correlation in both children and adults (peds: 0.88, 95% CI 0.86–0.90; adult: 0.89, 95% CI 0.86–0.90). By site, the highest correlation was axillary to oral among children in Hospital 1 (r = 0.98, 95% CI 0.92–1.00), while the lowest was axillary to tympanic for adults in Hospital 3 (r = 0.71, 95% CI 0.65–0.77). 882 subjects (334 pediatric, 548 adult) were assessed using all three measurement methods. 313 (159 pediatric, 154 adult) met AFI inclusion criterion by at least one method. From 49% to 63% of subjects at any site met the criterion by two or three methods (table). Results in hospitals 1, 2 and 4 were similar and grouped for analysis. In every site, subjects were detected by oral who would not have been detected using axillary or tympanic. Only in Hospital 3, subjects were detected by tympanic alone. No subjects in any site met the criterion by axillary measurement alone. Conclusion Accurate measurement of body temperature is essential for AFI surveillance, but literature on methodology is limited. We demonstrate that multiple modes of measurement increased detection of febrile patients. The most sensitive combination was oral and tympanic. Axillary measurement did not improve detection.

Body Temperature Measurement

Abstract The temperature measurement is essential during the physical examination since it helps to detect abnormalities on animal health. In addition, it should be done in the shortest possible time to avoid stress. The objective of this research is to calculate the correlation between rectal temperature and the superficial body temperature by means of a digital infrared thermometer. Ten alpacas huacaya from the center of development Alpaquero (CEDAT-DESCOSUR), located in Arequipa region at 4,365 m.a.s.l, and eight alpacas huacaya of the zootechnical and technological unit (UZYT) of the Universidad Cientifica del Sur, located in Lima at 0 m.a.s.l., were used. Rectal temperature measurement (RECTAL) was done with a veterinary clinical thermometer for one minute. Superficial body temperature measurement was conducted with infrared thermometer model CENTER 350®, at a distance of between 20 to 25 cm. Six measuring points were established by infrared thermometer: the outer zone of the nose (ON), the inner zone of the nose (IN), the extreme zone of ear (EE), middle zone of ear (ME), lower zone of the ear (LE) and the belly of the animal (BE). Rectal temperatures were measured at the same time as superficial body temperatures. Pearson’s correlation coefficient and graphs were calculated using an R software package called “CORRGRAM.” The results are presented in Table 1. Mean and deviation standard for rectal temperature from CEDAT-DESCOSUR and UZYT were 38.03 ± 0.37 and 37.46 ± 0.35 ° C, respectively. The results showed that there is a major correlation between rectal temperature and the temperature of the middle of the ear and the outer zone of the nose. In conclusion, there is a highly significant correlation between rectal temperature and superficial body temperature in some areas of the body, being an alternative option for the prediction of temperature in alpacas.

Objective: The accuracy of different non-invasive body temperature measurement methods in intensive care unit (ICU) patients is uncertain. We aimed to study the accuracy of three commonly used methods. Design: Prospective observational study. Setting: ICUs of two tertiary Australian hospitals. Participants: Critically ill patients admitted to the ICU. Interventions: Invasive (intravascular and intra-urinary bladder catheter) and non-invasive (axillary chemical dot, tympanic infrared, and temporal scanner) body temperature measurements were taken at study inclusion and every 4 hours for the following 72 hours. Main outcome measures: Accuracy of non-invasive body temperature measurement methods was assessed by the Bland–Altman approach, accounting for repeated measurements and significant explanatory variables that were identified by regression analysis. Clinical adequacy was set at limits of agreement (LoA) of 1C compared with core temperature. Results: We studied 50 consecutive critically ill patients who were mainly admitted to the ICU after cardiac surgery. From over 375 observations, invasive core temperature (mostly pulmonary artery catheter) ranged from 33.9C to 39C. On average, the LoA between invasive and non-invasive measurements methods were about 3C. The temporal scanner showed the worst performance in estimating core temperature (bias, 0.66C; LoA, 1.23C, +2.55C), followed by tympanic infrared (bias, 0.44C; LoA, 1.73C, +2.61C) and axillary chemical dot methods (bias, 0.32°C; LoA, 1.64C, +2.28C). No methods achieved clinical adequacy even accounting for significant explanatory variables. Conclusions: The axillary chemical dot, tympanic infrared and temporal scanner methods are inaccurate measures of core temperature in ICU patients. These non-invasive methods appeared unreliable for use in ICU patients.

Abstract Temperature measurement is essential during physical examination since it helps to detect abnormalities in animal health. Moreover, measurement should be done within the shortest possible time to avoid stress. The objective of this study was to determine the correlation between rectal temperature and the superficial body temperature using a digital infrared thermometer. Ten Huacaya alpacas from the DESCOSUR Center of Alpaca Development in Toccra, located in the Arequipa region, Perú at 4,365 m above sea level (MASL), and eight Huacaya alpacas from the Zootechnical and Technological Unit of the Universidad Cientifica del Sur, in Lima at 5 MASL, were studied. Rectal temperatures were obtained using a veterinary clinical thermometer for one minute. Superficial body temperature measurement was carried out with a CENTER 350® infrared thermometer, at a distance between 10 to 25 cm from the measured site. Six measuring points were used. Rectal temperatures were measured at the same time as the superficial body temperatures. The Statistical Analysis System (SAS®) University Edition, 2018 was used to perform Pearson’s correlation coefficient and graphs were made using the CORRGRAM R software package. Correlations with rectal temperature were significantly (P < 0.01) higher with the middle zone of the ear and the outer zone of the nose (0.75 and 0.69, respectively). In conclusion, the results in the present study indicated a significant positive correlation between rectal and infrared temperatures at different anatomical points in alpacas. Highly significant correlations were observed between the rectal temperature and the middle zone of the ear and the outer zone of the nose. These results could be used to perform an alternative method to predict body temperature by infrared temperature in alpacas; however, further testing is required in the field to validate these estimates.

Temperature Measurement System

Today, the most serious threat to global health is the continuous outbreak of respiratory diseases, which is called Coronavirus Disease 2019 (COVID-19). The outbreak of COVID-19 has brought severe challenges to public health and has attracted great attention from the research and medical communities. Most patients infected with COVID-19 will have fever. Therefore, the monitoring of body temperature has become one of the most important basis for pandemic prevention and testing. Among them, the measurement of body temperature is the most direct through the Forehead Thermometer, but the measurement speed is relatively slow. The cost of fast-checking body temperature measurement equipment, such as infrared body temperature detection and face recognition temperature machine, is too high, and it is difficult to build Disease Surveillance System (DSS). To solve the above-mentioned problems, the Intelligent pandemic prevention Temperature Measurement System (ITMS) and Pandemic Prevention situation Analysis System (PPAS) are proposed in this study. ITMS is used to detect body temperature. However, PPAS uses big data analysis techniques to prevent pandemics. In this study, the campus field is used as an example, in which ITMS and PPAS are used. In the research, Proof of Concept (PoC), Proof of Service (PoS), and Proof of Business (PoB) were carried out for the use of ITMS and PPAS in the campus area. From the verification, it can be seen that ITMS and PPAS can be successfully used in campus fields and are widely recognized by users. Through the verification of this research, it can be determined that ITMS and PPAS are indeed feasible and capable of dissemination. The ITMS and PPAS are expected to give full play to their functions during the spread of pandemics. All in all, the results of this research will provide a wide range of applied thinking for people who are committed to the development of science and technology.

The purpose of this research is to conduct aerodynamics study and design a hybrid drone system of fixed-wing and multi-copter. The mission of this drone is to measure human body temperature during COVID19 pandemic. The specific aim of the drone is to fly and cover larger industrial areas roughly about 50 km2 with longer flying time than the conventional drone, of about 1.5 hours. The applications of the simulation software such as XFLR5 and ANSYS have a big impact in identifying areas that need to be improved for the drone system. XFLR5 software was used to compare the characteristics of different airfoils with highest lift over drag, L/D ratio. Based on the airfoil selection, it was found that NACA 4412 airfoil produces the highest L/D ratio. The detailed geometry of the drone system includes a fuselage length of 1.9 meters and wingspan of 2 meters. Moreover, 10 sheets of solar panels were placed along the wing for sustainable flight operation to cover wider areas of mission. The structural analysis was done on ANSYS to test the elastic stress, equivalent strain, deformation, factor of safety pressure as well as lift and drag forces under various operational conditions and payloads. The landing gear was analyzed for harsh landing. ANSYS Computational Fluid Dynamics (CFD) was utilized to study the aerodynamics of the drone at different parameters such as the velocities and angles of attack during the operation. This design ensures the stability of the drone during the temperature measurement phase. The best thermal-imaging camera for such purpose would be the Vue Pro R 336, 45° radiometric drone thermal camera with a resolution of 640 x 512 pixels. This camera has the advantage of a permanent continuous out focus that give the ability of taking measurements even if there was changing on the altitude or any kind of vibrations.
