COVID-19 as many-faced Janus. On the classification of a new coronavirus infection

The spectrum of the clinical manifestations in patients with COVID-19 varies from asymptomatic to severe forms of the disease leading to death. The most commonly affected in patients with COVID-19 system is the respiratory system, but other organ systems can also be affected by the virus. We propose a classification of the clinical forms of COVID-19, which includes: acute respiratory infection (affecting only the upper respiratory tract); pneumonia: without ARF, with ARF; anosmia/parosmia/cacosmia; cerebral form (meningitis, meningoencephalitis); gastrointestinal form, including hepatitis; oligosymptomatic form/asymptomatic form; combined forms. Sepsis, septic (infectious-toxic) shock; DIC, thrombosis and thromboembolism are proposed to be considered as complications of the underlying disease. Present classification can help clinicians to diagnose COVID-19 at an early stage, identify atypical infection forms, and assign appropriate treatment. Key words: COVID-19, classification, clinical manifestations
