Understanding Severe Viral Infections

This observational study aims to understand why some people get very sick from common viral infections like those caused by EBV, HSV, VZV, HPV, and CMV, even when they don't have known immune problems. Researchers want to find immune system weaknesses or genetic factors that make individuals more prone to severe or unusual viral infections. You may be able to join if you are between 2 and 100 years old and have a confirmed severe or unusual viral infection. This study is not testing any specific treatments or interventions. The goal is to identify these underlying causes over a 10-year period.
