In the field of epidemiology, infrared light is employed in several innovative ways to monitor and control diseases. The key applications include:
Thermography: Infrared thermography is used to detect abnormal body temperatures, which can be indicative of infectious diseases. This technology became particularly useful during the COVID-19 pandemic for mass screening in public places. Remote Sensing: Satellites equipped with infrared sensors can monitor environmental conditions that influence the spread of diseases. For example, changes in vegetation and water bodies can affect the prevalence of vector-borne diseases like malaria. Wearable Devices: Wearables that use infrared sensors can continuously monitor physiological parameters such as skin temperature and blood flow. These devices are instrumental in early detection and management of chronic conditions.
