No One Really Knows Why COVID Spikes in Summer
Since the pandemic’s earliest days, epidemiologists have been waiting for the coronavirus to finally snap out of its pan-season spree. No more spring waves like the first to hit the United States in 2020, no more mid-year surges like the one that turned Hot Vax Summer on its head. Eventually, or so the hope went, SARS-CoV-2 would adhere to the same calendar that many other airway pathogens stick to, at least in temperate parts of the globe: a heavy winter
The next stage of COVID is starting now
To be a newborn in the year 2023—and, almost certainly, every year that follows—means emerging into a world where the coronavirus is ubiquitous. Babies might not meet the virus in the first week or month of life, but soon enough, SARS-CoV-2 will find them. “For anyone born into this world, it’s not going to take a lot of time for them to become infected,” maybe a year, maybe two, says Katia Koelle, a virologist and infectious-disease modeler at Emory University.
Nasal Vaccines Are Here – The Atlantic
Since the early days of the coronavirus pandemic, a niche subset of experimental vaccines has offered the world a tantalizing promise: a sustained slowdown in the spread of disease. Formulated to spritz protection into the body via the nose or the mouth—the same portals of entry most accessible to the virus itself—mucosal vaccines could head SARS-CoV-2 off at the pass, stamping out infection to a degree that their injectable counterparts might never hope to achieve.
Now, nearly three years into
We May Never Be ‘Fully Vaccinated’
For nearly a year now, the phrase fully vaccinated has carried a cachet that it never did before. Being fully vaccinated against COVID-19 is a ticket for a slate of liberties—a pass to travel without testing and skip post-exposure quarantine, per the CDC, and in many parts of the country, a license to enter restaurants, gyms, and bars. For many employees, full vaccination is now a requirement to work; for many individuals, it’s a must for any socialization at all.
Delta Has Changed the Pandemic Endgame
In September 2020, just before COVID-19 began its wintry surge through the United States, I wrote that the country was trapped in a pandemic spiral, seemingly destined to repeat the same mistakes. But after vaccines arrived in midwinter, cases in the U.S. declined and, by summer’s edge, had reached their lowest levels since the pandemic’s start. Many Americans began to hope that the country had enough escape velocity to exit its cycle of missteps and sickness. And though
Why a Variant’s Deadliness Is So Hard to Define
The coronavirus is on a serious self-improvement kick. Since infiltrating the human population, SARS-CoV-2 has splintered into hundreds of lineages, with some seeding new, fast-spreading variants. A more infectious version first overtook the OG coronavirus last spring, before giving way to the ultra-transmissible Alpha (B.1.1.7) variant. Now Delta (B.1.617.2), potentially the most contagious contender to date, is poised to usurp the global throne.
Alphabetically, chronologically, the virus is getting better and better at its primary objective: infecting us. And
