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

U07: Emergency use of U07

The U07 code classification in the ICD-10 WHO 2016 version pertains to health emergencies when conditions are of such a high public health importance that provisional categories must be quickly implemented. This group includes diseases that are new to the medical field or diseases where circumstances have dramatically changed. They are often highly infectious, rapidly spreading, and can cause severe symptoms. These conditions affect various systems of the body depending on the specific disease. Symptoms can be highly varied, including respiratory ailments, fevers, body aches, and more uncommon, novel symptoms. The disease progression can differ greatly, from mild cases to severe or even fatal outcomes, again contingent on the specific disease. The transmission of these diseases often includes person-to-person contact, but can also include animal to person contact or indirect contact.
