![]() ![]() That means about 1% of the virus’ genome is different from its starting point. Stuart Campbell Ray, an infectious disease expert at Johns Hopkins, said the current omicron variants have about 100 genetic differences from the original coronavirus strain. The achievements add up to a new normal where COVID-19 “doesn’t need to be at the forefront of people’s minds,” said Natalie Dean, an assistant professor of biostatistics at Emory University. “The pandemic really catalyzed some amazing science,” said Friedrich.įILE - A nurse processes COVID-19 rapid antigen tests at a testing site in Long Beach, Calif., Jan. We continue to monitor how the virus is changing by looking for it in wastewater. We built mathematical models to get ready for worst-case scenarios. ![]() Humans unlocked the virus' genetic code and rapidly developed vaccines that work remarkably well. Resistance to stay-at-home orders and vaccine mandates may be the pandemic's legacy. Trust has eroded in public health agencies, furthering an exodus of public health workers. Consider that in the United States, daily hospitalizations and deaths, while lower than at the worst peaks, have not yet dropped to the low levels reached during summer 2021 before the delta variant wave.Īt any moment, the virus could change to become more transmissible, more able to sidestep the immune system or more deadly. We've become numb to the daily death toll, Topol says, but we should view it as too high. Eric Topol, head of Scripps Research Translational Institute in California. “Whatever the virus is doing today, it’s still working on finding another winning path,” said Dr. It spreads easily from person to person, riding respiratory droplets in the air, killing some victims but leaving most to bounce back without much harm.įILE - Extremely light traffic moves along the 110 Harbor Freeway toward downtown Los Angeles in the mid-afternoon of March 20, 2020. With the pandemic still killing 900 to 1,000 people a day worldwide, the stealthy virus behind COVID-19 hasn't lost its punch. Saturday marks three years since the World Health Organization first called the outbreak a pandemic, March 11, 2020, and the United Nation's health organization says it's not yet ready to say the emergency has ended. “Maybe that will help people to understand how connected we are.” “New variants emerging anywhere threaten us everywhere,” said virus researcher Thomas Friedrich of the University of Wisconsin-Madison. The virus appears here to stay, along with the threat of a more dangerous version sweeping the planet. Yet most people have resumed their normal lives, thanks to a wall of immunity built from infections and vaccines. On the third anniversary of the COVID-19 pandemic, the virus is still spreading, and the death toll is nearing 7 million worldwide. ![]()
