Antonio Arrieta: PTN Principal Investigator at Children’s Hospital of Orange County

Director of Pediatric Infectious Diseases at Children’s Hospital of Orange County (CHOC), California, Dr. Antonio Arrieta is a board-certified pediatric infectious disease specialist who leads a team of 5 physicians providing inpatient and outpatient consults for the hospital and the community. He also directs the pediatric HIV treatment center.

Physicians trained in pediatric infectious disease treat a variety of infectious and immunologic afflictions, such as those caused by bacteria, viruses, fungi, and parasites. These specialists are also consulted regarding conditions that are complicated or atypical, including respiratory infections, bone and joint infections, tuberculosis, HIV/AIDS, hepatitis, and meningitis.

As a pediatric infectious disease specialist, Dr. Arrieta understands the unique symptoms, treatments, and outcomes associated with infectious diseases in children, which can differ quite radically from those of adults with the same conditions. He uses this knowledge to inform his research, which primarily addresses antifungal agents, pediatric HIV, and the safety, efficacy, and pharmacokinetics of medicines used to treat and prevent infectious diseases in children. Dr. Arrieta is a principal investigator for many studies being conducted at CHOC.

Although free time can be in short supply, when Dr. Arrieta has a spare moment, he enjoys playing squash, traveling, sampling various ethnic foods, visiting the local beach, and movie-watching. He also enjoys spending time with his beautiful wife and two children (ages 21 years and 15 years).
