The latest evidence about Covid is largely positive. A few weeks ago, many experts and journalists were warning that the initial evidence from South Africa — suggesting that Omicron was milder than other variants — might turn out to be a mirage. It has turned out to be real.
“In hospitals around the country, doctors are taking notice,” my colleagues Emily Anthes and Azeen Ghorayshi write. “This wave of Covid seems different from the last one.”
There are at least three main ways that Omicron looks substantially milder than other versions of the virus:
- Less hospitalization
Somebody infected with Omicron is less likely to need hospital treatment than somebody infected with an earlier version of Covid.
An analysis of patients in Houston, for example, found that Omicron patients were only about one-third as likely to need hospitalization as Delta patients. In Britain, people with Omicron were about half as likely to require hospital care, the government reported. The pattern looks similar in Canada, Emily and Azeen note.
- Milder hospitalization
Omicron is not just less likely to send somebody to the hospital. Even among people who need hospital care, symptoms are milder on average than among people who were hospitalized in previous waves.
A crucial reason appears to be that Omicron does not attack the lungs as earlier versions of Covid did. Omicron instead tends to be focused in the nose and throat, causing fewer patients to have breathing problems or need a ventilator.
As Dr. Rahul Sharma of NewYork-Presbyterian/Weill Cornell told The Times, “We’re not sending as many patients to the I.C.U., we’re not intubating as many patients, and actually, most of our patients that are coming to the emergency department that do test positive are actually being discharged.”
- And deaths?
In the U.S., mortality trends typically trail case trends by about three weeks — which means the Omicron surge, which began more than a month ago, should be visible in the death counts. It isn’t yet:
Covid deaths will still probably rise in the U.S. in coming days or weeks, many experts say. For one thing, data can be delayed around major holidays. For another, millions of adults remain unvaccinated and vulnerable.
But the increase in deaths is unlikely to be anywhere near as large as the increase last summer, during the Delta wave.
The bottom line
Before Omicron, a typical vaccinated 75-year-old who contracted Covid had a roughly similar risk of death — around 1 in 200 — as a typical 75-year-old who contracted the flu. (Here are the details behind that calculation, which is based on an academic study.)
Omicron has changed the calculation. Because it is milder than earlier versions of the virus, Covid now appears to present less threat to most vaccinated elderly people than the annual flu does.
