Respiratory viruses, thrown out of whack by Covid, appear to be falling back into seasonal order
As we head into the fourth Northern Hemisphere winter of the Age of Covid, respiratory viruses appear to be falling back into seasonal order, experts tell STAT.
In the depths of the Covid-19 pandemic, something strange happened: For a year or two, illnesses that used to emerge like clockwork when fall and winter arrived — flu, RSV, and the myriad viruses that cause colds — did not sicken us.
The cause now appears clear: The measures we took to avoid the new disease, including isolating and social distancing, muscled most other respiratory pathogens out of the cold-and-flu-season picture.
