This page provides clinicians and public health professionals with key information and evidence for clinical considerations when diagnosing and managing patients infected with SARS-CoV-2, the virus that causes COVID-19. For evidence-based treatment recommendations for COVID-19, visit the National Institutes of Health (NIH) COVID-19 Treatment Guidelines prepared by the COVID-19 Treatment Guidelines Panel. Also see Variants of the Virus and Vaccines for COVID-19.

Key Points

  • The clinical presentation of COVID-19 varies from asymptomatic infection to critical illness; symptoms can change during the course of illness.
  • When testing for current SARS-CoV-2 infection, CDC recommends that clinicians use molecular (polymerase chain reaction [PCR] or nucleic acid amplification test [NAAT]) or antigen tests (viral tests) that detect SARS-CoV-2 or its components, not a serologic test that detects antibodies. A chest radiograph or computed tomography (CT) images alone are not recommended to diagnose COVID-19, but might be helpful in assessing and managing COVID-19 patients.
  • Clinicians caring for populations including children, pregnant and recently pregnant people, people who are moderately or severely immunocompromised, people with confirmed or suspected multisystem inflammatory syndrome, and people with post-COVID conditions may have additional clinical considerations.
  • When treating patients with COVID-19, the National Institutes of Health (NIH) recommends clinicians consider treating patients according to risk of progression to severe COVID-19 or the severity of COVID-19. Patients who are reinfected with SARS-CoV-2 likely will experience less severe illness than during the initial infection, but some patients will experience more severe illness.
