Table 1. Categories of infections Categories of infections formed by grouping all reported ICD-10 codes for infectious diseases and fever reports into clinically relevant entities. Altogether 113,884 ICD-10 codes for infections and 54,501"yes"fever reports were categorized. Every ICD-10 code with three characters comprises also all its sub-codes with four characters, unless otherwise indicated. n % out of ICD-10 codes 1. FEVER 1.1.
