U00-U49: Provisional assignment of new diseases of uncertain etiology or emergency use

U17: Emergency use of U17

The U17 classification in ICD-10 WHO 2016 pertains to a set of conditions necessitating emergency use in the healthcare realm. These circumstances go beyond routine health complications, often relating to crises or unforeseen health situations such as pandemics or significant outbreaks of new diseases. The range of conditions falling under this category is vast, extending from respiratory diseases to viral diseases not classified elsewhere. Conditions within this group are typically highly transmissible, often through respiratory droplets or contact with an infected individual. Symptoms can differ widely, as they depend on the specific condition. However, fever, cough, shortness of breath, and fatigue are common among many of these illnesses. The progression of these diseases is usually rapid, which, along with the wide range of potential effects on different body systems, underscores the importance of their designation for emergency use.
