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

U40: Emergency use of U40

The ICD-10 code U40 represents a special group of conditions that have been granted an emergency use authorisation by health authorities, such as the World Health Organisation. This means these conditions are newly recognised and urgently require further research and understanding. Diseases in this category can come from a variety of origins and have widely differing symptoms and disease progressions. They may be infectious, affecting humans through direct contact, airborne transmission, or vector-borne transmission, or they could be non-infectious. Signs of these diseases can range from mild like a slight cough or fever, to severe cases having life-threatening implications. The progression of the disease can be rapid or slow and can have varied impact on different body systems. Precise understanding of these conditions is vital for targeted treatment and control measures.
