SARS-CoV-2

The vaccines saved 2.9 million lives, prevented 12.5 million hospitalizations, and saved $500 billion in hospitalization costs, according to a recently published analysis. They were – and are – hugely important to Americans' health and prosperity.
Vaccination is a pillar of disease prevention, but Americans are under-vaccinated. We need a multi-pronged public education campaign with participation from politicians and celebrities of every stripe.
In this radio conversation, John Batchelor and I discuss the effectiveness of vaccines and the challenges posed by new variants of SARS-CoV-2 (the virus that causes COVID-19) such as the now-dominant JN.1.
A retired psychologist attacked an article of mine about deranged Florida Surgeon General Joseph Ladapo's views of public health policies toward the COVID-19 pandemic. His assertions ranged from the preposterous to the merely inaccurate.
Even as we find ourselves in a new wave of COVID-19, the politicizers and minimizers of the pandemic won't let up. They continue to spread disinformation about both the effectiveness and safety of masks.
There are upticks in early indicators of a COVID surge, including hospitalizations, test positivity, and SARS-CoV-2 concentrations in wastewater. And a new Omicron subvariant is rapidly gaining in prevalence. We need to prepare.
Long COVID remains an enigma wrapped within a conundrum. Many individuals claim the affliction. But without a consensus on its diagnosis, unraveling its underlying physiologic changes, let alone therapeutic approaches, is a random walk. It's a lot a drunk searching for their keys under a streetlamp because the light is better. Two developments this week may well begin the unwrapping.
Long COVID burdens tens of millions of Americans and the nation's healthcare system, but our response to it has been fragmented and chaotic. We need to address it without delay, with more research and better access to treatment.
The spread of SARS-CoV-2 infections through many mammal species in the wild raises the specter of deer becoming a SARS-CoV-2 reservoir — a permanent home for the virus and a regular source of outbreaks in other animals, including humans.
In order to prepare for the emergence of new SARS-CoV-2 "variants of concern" or other epidemic coronaviruses, researchers are taking a variety of approaches to creating vaccines that will protect against not only known viruses but also against variants that have not yet appeared.
Long COVID will take a toll on the nation's healthcare system for the foreseeable future, but we can reduce new cases by treating acute COVID infections with a commonly prescribed, inexpensive medicine.
The most infectious subvariant of the SARS-CoV-2 virus yet discovered is spreading through the U.S., and experts are predicting a January-February surge of COVID cases. A corollary is that we will also have more cases of long COVID, which is worrisome given new findings that long COVID, like acute infections, can be fatal. The best way to avoid long COVID is not to get infected in the first place.
