COVID-19 continues to cause deaths post-emergency declaration

Five years ago, the World Health Organization (WHO) declared an outbreak of a new virus known as COVID-19. The emergency status was lifted on May 5, 2023, but some deaths and infections continue to be reported. As of February 2025, the WHO recorded 2,800 deaths related to COVID-19. This anniversary has prompted some media attention, with articles discussing how society has largely forgotten about the virus and how unprepared we are for future pandemics. Carl Zimmer, a science writer, is releasing a book titled "Air-Borne: The Hidden History of The Life We Breathe," which raises concerns about the low awareness of airborne diseases among both the public and health professionals. There were misunderstandings during the pandemic about how COVID-19 spreads. Initially, the WHO did not fully acknowledge the airborne nature of the virus, focusing instead on short-range transmission. Experts like Lidia Morawska challenged this view, providing evidence that COVID-19 could spread beyond one meter. This led to the WHO updating its guidelines to include long-range airborne transmission. Many infections occurred in poorly ventilated indoor spaces. Notable outbreaks happened at events in the Philippines, such as a cockfighting derby and an online betting event, where people gathered in crowded areas. Throughout the pandemic, there was little emphasis on controlling airborne transmission indoors. Countries like Japan approached the issue proactively, promoting measures such as improving ventilation in enclosed spaces. They encouraged people to avoid crowds, closed spaces, and close contact—known as the "3Cs." As the world moves forward, experts continue to emphasize the importance of understanding airborne diseases for better pandemic preparedness.
