Some experts recommend longer than 6 months following anti-B cell antibodies. Infants born to mothers with onset of maternal varicella more than 5 days prior to delivery usually have a benign course, attributed to passive transfer of maternal antibody across the placenta. It replicates at the site of entry in the nasopharynx and in regional lymph nodes. Some investigations have identified asthma, use of steroids, and vaccination at younger than age 15 months as risk factors for breakthrough varicella, but other investigations did not. Polymerase chain reaction (PCR) is the method of choice for laboratory diagnosis of varicella.
