In 1995, the US launched a varicella vaccination program, leading to a significant drop in cases. However, breakthrough infections still occur, and clinical diagnosis has become less reliable as the virus has evolved. Join us to hear current recommendations for what to consider in the differential diagnosis and how emerging evidence may impact public health and your practice.
