Consultants have made it clear that the finish of the COVID-19 nationwide emergency, which was lifted on Might 11, 2023, doesn’t imply an finish to the pandemic. However this shift indicators a outstanding turning level in a pandemic that’s properly into its fourth 12 months – one thing that few may have imagined when the U.S. nationwide emergency went into impact in March 2020.
Likewise, the World Well being Group’s announcement on Might 5 that it was ending the COVID-19 public well being emergency of worldwide concern that had been in place since January 2020 is indicative that the pandemic has entered a brand new chapter.
It’s formidable to look again at our protection and slender it right down to only a handful of standout tales amid all of the twists and turns of the pandemic. However listed below are 5 tales from The Dialog’s archives that resonated with us, written by students who helped to light up advanced points at pivotal moments within the pandemic.
1. An entire new vocabulary
It’s somewhat onerous to recollect the times when phrases like pandemic, endemic illnesses, mRNA, variant and spike proteins weren’t part of our vernacular or on a regular basis conversations. However I vividly recall the day that the COVID-19 pandemic was declared and a buddy requested me “What precisely is a pandemic?” It seems lots of people had been asking that query and questioning in regards to the distinction between an outbreak of an infectious illness, an epidemic and a pandemic.
Rebecca S.B. Fischer, an assistant professor of epidemiology at Texas A&M College, put it in easy phrases: An outbreak is a small however uncommon improve within the anticipated variety of instances of a given illness, whereas the time period epidemic is used when an infectious illness outbreak is getting larger and spreading over a broader geographic space. A pandemic, however, is used when a illness is “worldwide and uncontrolled.”
She went on to say that some epidemiologists reserve the time period pandemic for when a illness is being sustained in newly affected areas by means of native transmission – characterization of the state of COVID-19 in March 2020.

2. Comparisons to the 1918 flu ran rife
From the earliest days of the COVID-19 pandemic, it was inconceivable to overlook the haunting similarities between it and the 1918 flu pandemic, which led to at the least 50 million deaths worldwide between 1918 and 1920. Well being care consultants and the media made frequent comparisons between the 2, pointing to similarities in attitudes about mask-wearing and college closures in addition to within the patterns of illness waves, spikes and surges.
However whereas the 2 once-in-a-century occasions have shared loads of likenesses, the comparability additionally typically led to public misunderstandings about how the COVID-19 pandemic may play out, wrote historian Mari Webel and pediatric infectious illness specialist Megan Culler Freeman, each from the College of Pittsburgh. They clarify that key variations within the sociopolitical context of the 1918 flu interval, in addition to marked variations between the virology behind the 2 illnesses, set the 1918 flu and COVID-19 on completely different paths.
“Individuals search solutions from the experiences of influenza in 1918-19 for a basic motive: It ended.”

3. How and when pandemics finish
In late 2020, folks had been naturally questioning when and the way the COVID-19 pandemic would finish, and the way we’d understand it was over.
Nükhet Varlik, a historian from Rutgers College who research illness, drugs and public well being, wrote an astute piece in October 2020 in regards to the difficulties of predicting how the pandemic may play out. She presciently famous that “whether or not bacterial, viral or parasitic, nearly each illness pathogen that has affected folks over the past a number of thousand years remains to be with us, as a result of it’s practically inconceivable to completely eradicate them.” These embody illnesses like tuberculosis, leprosy, measles and plague.
“Hopefully COVID-19 won’t persist for millennia,” Varlik wrote. However she went on to say that politics are essential, noting how when vaccination applications are weakened, infections can “come roaring again.”
“Given such historic and modern precedents, humanity can solely hope that the coronavirus that causes COVID-19 will show to be a tractable and eradicable pathogen. However the historical past of pandemics teaches us to anticipate in any other case.”

4. The halfway level
The summer time of 2021 felt like a very grueling second in time – when pleasure and optimism over the launch of the primary vaccines to guard towards COVID-19 had given approach to despair over the stronghold of vaccine resistance and basic exhaustion with all issues COVID. After which got here the delta variant.
Epidemiologist Katelyn Jetelina, previously from the College of Texas Well being Science Heart at Houston, captured 18 months of the COVID-19 pandemic in a collection of seven retrospective charts that put the entire excessive and low factors into stark reduction. “The race between vaccination and variant unfold was upon us,” Jetelina wrote. “The combat was removed from over.”
The identical should be true at present.

5. How omicron altered the course of the pandemic
When the omicron variant arrived on the scene in late 2021 and unfold globally in early 2022, it quickly turned clear that it may convey a few shift within the pandemic. With its skill to unfold simply and to additionally trigger milder illness than prior variants, omicron had the potential to behave as a pure vaccine of kinds – producing widespread immunity with the assistance of the prevailing COVID-19 vaccines.
However the omicron variant had loads of surprises in retailer. For one, it gave rise to a household of variants and sublineages that to at the present time are conserving researchers guessing, with the most recent omicron subvariant, XBB.1.16, gaining floor throughout the U.S. and worldwide as of mid-Might 2023.
In January 2022, immunology researchers Prakash Nagarkatti and Mitzi Nagarkatti, from the College of South Carolina, defined how the immune system responds to infections and the way it remembers these threats by means of “immunological reminiscence.”
This left room for hope, they wrote, that “when new variants of SARS-CoV-2 inevitably come up, omicron may have left the inhabitants higher geared up to combat them. So the COVID-19 vaccines mixed with the omicron variant may feasibly transfer the world to a brand new stage within the pandemic – one the place the virus doesn’t dominate our lives and the place hospitalization and demise are far much less widespread.”
