COVID-19 is a new disease. Currently there are limited data and information about the impact of many underlying medical conditions and whether they increase the risk for severe illness from COVID-19. Based on what we know at this time, adults of any age with the following conditions might be at an increased risk for severe illness from the virus that causes COVID-19:

  • Asthma (moderate-to-severe)
  • Cerebrovascular disease (affects blood vessels and blood supply to the brain)
  • Cystic fibrosis
  • Hypertension or high blood pressure
  • Immunocompromised state (weakened immune system) from blood or bone marrow transplant, immune deficiencies, HIV, use of corticosteroids, or use of other immune weakening medicines
  • Neurologic conditions, such as dementia
  • Liver disease
  • Overweight (BMI > 25 kg/m2, but < 30 kg/m2)
  • Pulmonary fibrosis (having damaged or scarred lung tissues)
  • Thalassemia (a type of blood disorder)
