Biological effects may include at least one of inactivating and/or inhibiting growth of one or more pathogens, upregulating a local immune response, increasing endogenous stores of nitric oxide, releasing nitric oxide from endogenous stores, and inducing an anti-inflammatory effect. Wavelengths of light are selected based on intended biological effects for one or more of targeted tissue types and targeted pathogens. Light treatments may provide multiple pathogenic biological effects, either with light of a single wavelength or with light having multiple wavelengths. Devices for light treatments are disclosed that provide light doses for inducing biological effects on various targeted pathogens and tissues with increased efficacy and reduced cytotoxicity. Particular illumination devices are disclosed that provide safe and effective treatments for upper respiratory tract infections, including coronaviridae and orthomyxoviridae.

A computerized method for controlling the operation of a laser therapy device is disclosed. A laser therapy device comprising laser diodes has a microprocessor for storing and executing instructions pertaining to the operation of the laser diodes within certain parameters. The computerized method detects the movement of the laser therapy device and alters the output of the laser diodes when a movement signal exceeds predetermined threshold parameters. The computerized method detects difference in temperature in certain areas, and patterns in temperature differences, for assistance in diagnosing ailments. The computerized method also detects differences in skin color to determine treatment areas. The computerized method also measures the distance of the laser therapy device to a treatment area. The microprocessor executes instructions then which can alter the output of the laser diodes or generate an alarm signal based on measurements received.
