Infectious Disease

We understand serious infections can pose serious risks to children and can spread quickly in communities. While infection can spread rapidly in a small child, the involvement of a pediatric infectious disease specialist can make all the difference. CHOC infectious disease specialists are highly experienced, board-certified pediatric subspecialists who understand the changing nature of infectious disease and children.

Conditions We Treat

Our specialists provide the early diagnosis and intervention necessary to prevent the further spread of serious, life-threatening infections.

Early Intervention For Life-Threatening Conditions

The CHOC infectious disease physician team is available 24-hours-a-day to provide expert diagnosis and treatment for acute or life-threatening conditions, such as:

  • Infectious diseases (including multi-resistant bacteria)
  • Congenital and perinatal infections, including HIV
  • Opportunistic infections in the immunocompromised patient
  • Respiratory, viral and fungal infections
  • Immunocompromised host
  • Community outbreaks

Outpatient Management for Chronic Conditions

Many conditions may be safely managed through home IVs and oral regimens. For the benefit of patients and their families, every effort is made to transition care to the home environment as quickly – and as safely – as possible. The CHOC infectious disease physician team provides comprehensive outpatient care for:

  • HIV – an accredited program serving the greater Orange County area
  • Recurrent/periodic fever or fever of unknown origin
  • Tuberculosis and other chronic infections
  • Coccidiomycosis and other endemic fungal infections
  • Travel medicine for children
  • Infections in primary immune deficiencies
  • Viral hepatitis

Dedicated to Research

Researchers at CHOC Research Institute serve as principal investigators for several clinical research studies, providing patients with access to the newest treatment options available. Recent studies in infectious disease have focused on the development of vaccines, antiviral medications, and anti-fungal treatment options for common and serious infections.
