Respiratory Syncytial Virus
RSV is a 150 nanometer RNA virus that comes from a human orthopneumovirus that circulates in the winter primarily. Young children and infants infected with RSV mostly have upper respiratory tract symptoms where a subset develop lower respiratory tract disease known as bronchiolitis with the primary infection. It is the most common reason for hospitalization in infants between 0 and 6 months of age. Bronchiolitis appears as a wheezy, cough centric illness that rarely may progress to increased respiratory effort noted by wheezing, rales (lung crackles – sounds like stepping on leaves), chest wall rib retractions, grunting, fast breathing, nasal flaring and eventually respiratory hypoxia. If it persists, the event can rarely lead to respiratory collapse and death. Annually, 150 children under 5 years of age die from RSV in the US. Most of these children are premature births and have cardiopulmonary disease issues. Term healthy children rarely succumb to RSV in a serious way. A recent study of German infants and children hospitalized with RSV identified these risk factors: age <6 months, birth at 28–37 weeks gestational age, congenital defects, perinatal respiratory and cardiovascular disorders, and various other comorbidities as significant risk factors for ICU admission and death. ( Cai et. al. 2020) plus a mini lit review and a discussion on thanksgiving.

Covid Newsletter #74. Why are we seeing massive waves of RSV and Influenza A right now? These viruses normally circulate in the winter only. The answer is nuanced, but likely primarily because of the pandemics social distancing and hygiene activity. During the 2020-2022 cycle of Covid fear and mitigation of viral risk, most of us avoided the normal trappings of viral spread. We masked avoiding the viral droplet portal of entry most commonly used. We kept our children semi isolated from other children where most year to year viral transmission events occur. We practiced enhanced hand washing and sanitizing reducing natural viral spread through contact. In essence we stopped the normal propagation of respiratory virus for 2 years. A whole cycle of children between 0 and 2 years old are RSV and flu immune naive leading to a perfect host pool for spread. The 2 to 18 year olds have had a long pause in exposure reducing circulating virus specific antibodies to negligible levels leading to stronger infections and more spread. Anyone who has a child in college (me) has seen infection after infection pound these students this fall. It seems like they are always dealing with a viral illness. Immunity country wide will return in the coming year to these viral illnesses reverting to the old reality of winter predominance.
