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.
