What this Trial Is About
Researchers are investigating why some individuals without known immune system problems develop severe, persistent, or hard-to-treat viral infections. These infections include those caused by herpesviruses, papillomaviruses, adenoviruses, polyomaviruses, and influenza viruses. The study aims to identify immune or genetic defects that may make these infections more severe, helping to better understand the immune system and potentially guide new treatments. Participants include children and adults diagnosed with unusually severe viral infections, as well as their relatives, who may also join to help scientists understand if immune defects run in families. The study involves reviewing medical records and providing optimal therapy for the viral infection at the NIH Clinical Center. During the study, blood samples and skin biopsies may be taken to analyze the immune system, and researchers will monitor how the infection responds to treatment. Participants will have follow-up visits during and after their illness to track the infection's course and treatment response. The study includes detailed evaluations, laboratory tests, and specimen storage for future research. The primary goal is to identify immune or genetic factors linked to severe viral infections over a period of up to 10 years, with ongoing monitoring to understand these infections better.

- Children or adults who have recovered from a severe, persistent, or treatment-resistant viral infection
- Ongoing care by a referring physician
- Willingness to allow storage of blood and tissue samples for future analysis
- Male and female relatives aged 2 years or older may participate to help study genetic factors
- Relatives may be healthy or show signs of immune system issues
- Adult relatives or guardians must provide informed consent for participation
You will not qualify if you...
- Patients with known acquired or treatment-related immune deficiency, such as HIV infection or those receiving chemotherapy or high-dose steroids
- Women who are pregnant
- Any major health condition that would prevent compliance with the study requirements, as judged by the investigators
- Patients on immunosuppressive or immunomodulatory therapy for immune system disorders may be included only at the investigator's discretion
