Therefore, we question mass detection of febrile patients by using this method.
However, few studies have assessed their capacity for accurate detection of febrile patients in clinical settings.
In short, suitable live donors of samples for virus isolation or antigen detection are febrile, have mucosal erosions and clear lacrimal secretions.
Infrared measurements of forehead temperature proposed for mass detection of febrile subjects in airports and other places also produced largely disappointing results (Hausfater et al. 2008).
Mass detection of febrile patients by using this technique cannot be envisaged without accepting a high rate of false-positive results.
IRT has also been applied to the detection of febrile responses to systemic illness of cattle, including bovine viral diarrhoea (Schaefer et al., 2004) and respiratory disorders (Schaefer et al., 2007).
Our findings support the recommendations of the two reviews into AEFI surveillance in Australia, which were initiated because of the occurrence and delayed detection of febrile convulsions post STIV in 2010.
By implementing fever screening by NCITs at airports for the detection of febrile inbound passengers, which was confirmed by ear temperature readings, we obtained a fever prevalence that ranged from 0.08-0.100.08-0.10%) among the total inbound passengers.
Dengue has not reached an endemic status in Taiwan; nevertheless, we have implemented a fever screening program at airports for the early detection of febrile passengers with a dengue infection.
ITDS appeared to enable early detection of febrile persons entering healthcare facilities, where the undetected introduction of communicable diseases can lead to outbreaks among patients and staff (5, 16 – 16 ).
These studies provide proof-of-concept that infrared images of groups of pigs can be used to detect febrile responses at low levels of prevalence, and thus have potential as a disease detection and surveillance tool in swine barns.
