About the B97 Code Range
These codes identify a virus as the cause of a disease classified elsewhere. They distinguish the virus involved rather than the disease it causes.
B97 is organized by virus type, including adenovirus, enterovirus, coronavirus, retrovirus, respiratory syncytial virus, and other viral agents. B97.1 separates enteroviruses into unspecified, coxsackievirus, echovirus, and other enteroviruses. B97.2 distinguishes SARS-associated coronavirus from other coronaviruses.
B97.3 divides retroviruses into named types, including lentivirus, oncovirus, and specific human viruses. B97.8 separates human metapneumovirus from other viral agents.
