Devices, systems and methods relating to thermometer housings for attachment to hand-held thermometers for in situ differentiation between viral and non-viral infections

A thermometer housing sized and configured for attachment to a hand-held body thermometer such that the thermometer housing and hand-held body thermometer provide a hand-held fluorescence and temperature detector sized and configured to detect temperature and fluorescence emanating from a suspected infection at a target site, wherein,

• the thermometer housing comprises a detection system comprising a) an excitation portion comprising an excitation light source configured to emit excitation light adequate to elicit selectively detectable fluorescent light from the suspected infection at the target site, and b) a detection portion comprising a camera configured to selectively detect substantially only fluorescent light emanating from the target site,
• and wherein the hand-held fluorescence and temperature detector is operably connected to computer-implemented programming configured to a) accept fluorescent light data associated with the fluorescent light and thermal data associated with heat levels above ambient body temperature, and b) interpret the data to determine a probability whether the target site contains an infection.
