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.

Your Negative COVID Test Is Basically Meaningless
In early May, 27-year-old Hayley Furmaniuk felt tired and a bit congested, but after rapid-testing negative for the coronavirus two days in a row, she dined indoors with friends. The next morning, her symptoms worsened. Knowing her parents were driving in for Mother’s Day, she tested again—and saw a very bright positive. Which meant three not-so-great things: She needed to cancel with her parents; she had likely exposed her friends; a test had apparently taken three days to register what
What Controlling COVID Actually Means
And just like that, the national attitude on COVID is flipping like a light switch. As the United States descends the bumpy back end of the Omicron wave, governors and mayors up and down the coasts are extinguishing indoor mask mandates and pulling back proof-of-vaccination protocols. In many parts of the country, restaurants, bars, gyms, and movie theaters are operating at pre-pandemic capacity, not a face covering to be seen; even grade schools and universities have started to relax testing
Will Omicron Leave Most of Us Immune?
Even before Omicron hit the United States in full force, most of our bodies had already wised up to SARS-CoV-2’s insidious spike—through infection, injection, or both. By the end of October 2021, some 86.2 percent of American immune systems may have glimpsed the virus’s most infamous protein, according to one estimate; now, as Omicron adds roughly 800,000 known cases to the national roster each day, the cohort of spike-zero Americans, the truly immunologically naive, is shrinking fast. Virginia Pitzer,
How Many COVID-19 Booster Shots Will We Need?
Walter Barker has, since the fall of 2020, had five doses of COVID-19 vaccine. He’s already starting to ponder when he might need a sixth.
Barker, a 38-year-old office worker in New York, received his first two doses a year ago, as part of an AstraZeneca vaccine trial. But the shots, which haven’t been authorized by the FDA, couldn’t get him into some venues. Sick of having to test every time he went to a Yankees game, Barker nabbed a
Omicron Is Our Past Pandemic Mistakes on Fast-Forward
With Omicron, everything is sped up. The new variant is spreading fast and far. At a time when Delta was already sprinting around the country, Omicron not only caught up but overtook it, jumping from an estimated 13 to 73 percent of U.S. cases in a single week. We have less time to make decisions and less room to course-correct when they are wrong. Whereas we had months to prepare for Delta in the U.S., we’ve had only weeks
Our First Preview of How Vaccines Will Work Against Omicron
And there it is, the first trickle of data to confirm it. In the eyes of vaccinated immune systems, Omicron looks like a big old weirdo—but also, a kind of familiar one. That’s the verdict served up by several preliminary studies and press releases out this week, describing how well antibodies, isolated from the blood of vaccinated people, recognize and sequester the new variant in a lab. The news is … well, pretty much the middling outcome that experts have
You Can Get COVID and the Flu at the Same Time
In late February 2020, only a couple of weeks after the pandemic coronavirus disease had even received a formal name, a man with a terrible cough and fever showed up at one of the ProHealth Urgent Care centers in Queens, New York. At that point, no COVID-19 cases had yet been confirmed in New York City, but numbers were on the rise in spots across the country, and the man had recently been at a conference.
