"Seasonal Order Restored: Respiratory Viruses Decline"
Respiratory viruses, such as flu and RSV, are starting to fall back into their seasonal patterns after being disrupted by the Covid-19 pandemic. The measures taken to prevent the spread of Covid-19, such as social distancing and isolation, also prevented other respiratory pathogens from circulating. However, as Covid-19 restrictions eased, these viruses returned at unusual times and in unusual ways. Now, as we enter the fourth winter since the start of the pandemic, respiratory viruses are showing signs of returning to their pre-pandemic seasonal patterns. While the return to normal varies globally, experts believe that the temporary disappearance of these viruses created a larger population of susceptible individuals, leading to a surge in cases when they returned. The impact of Covid-19 on the seasonality of respiratory viruses is still uncertain, but experts suggest that as human behavior returns to normal, the viruses will behave as they did before.
