ICD is revised, every –
**Core Concept**
The International Classification of Diseases (ICD) is a globally used diagnostic tool for epidemiology, health management, and clinical purposes. It is revised periodically to reflect advances in medical science and to ensure that the classification remains relevant and accurate. The revision process involves a thorough review of existing codes, identification of gaps, and addition of new codes to cover emerging conditions.
**Why the Correct Answer is Right**
The ICD is revised every 10 years to ensure that it remains a useful tool for healthcare professionals and researchers. This revision process involves a collaborative effort between the World Health Organization (WHO) and experts from around the world. The revised ICD includes new codes for conditions such as Zika virus infection, SARS-CoV-2 infection, and other emerging diseases.
