Summary

This study looked at 537 patients with respiratory infection symptoms to see how the types of viruses and bacteria changed from the COVID-19 pandemic period to after it. Researchers used a special PCR test to detect multiple germs at once. The goal was to understand how pandemic measures like masking and social distancing affected the spread of other respiratory infections.
