Due to the coronavirus disease 2019 (COVID-19) pandemic, there is currently a need for accurate, quick, and easy-to-use diagnostic tools to help communities manage local outbreaks and assess the spread of the disease. sickness. The use of artificial intelligence in breath analysis techniques has shown potential in the diagnosis of various diseases by analyzing volatile organic compounds (VOCs) in exhaled air. This combined with their rapid, easy-to-use, and non-invasive nature, makes them a good candidate for diagnosing COVID-19 in large-scale public health operations. However problems remain with their implementation with respect to the infrastructure currently available to support their widespread use. Just as each of us has a unique fingerprint that sets us apart from others, every disease has a chemical signature that sets it apart from other illnesses and from normal health. Note that a number of diseases can be detected on the breath. Breath is an excellent raw material for diagnosis. It is available without the need for invasive and unsightly procedures is not dangerous, and can be savored over and over again as needed. Diagnosis, prognosis and monitoring of these conditions are complex and are based primarily on clinical criteria. Proper reatment of neurological conditions can significantly reduce symptoms, slow disease progression, and improve the patient's quality of life.
