Thanks to vaccines, there’s been a renewed sense of hope that we’ll move past COVID-19. Businesses have reopened. And many of us are once again spending time with family and friends. In short, life seems to be returning to normal.
But if you’ve watched the news lately, you know we’re not out of the woods just yet. A mutated form of the virus, known as the delta variant, is circulating worldwide. And it’s important we all know something about it.
It’s not uncommon for viruses to mutate, or change, over time. In fact, officials have already identified several COVID-19 mutations or variants. Experts watch these variants carefully because the variants can behave differently than the original virus strain from 2019.
Although there’s still a lot to learn about delta, there are several reasons the Centers for Disease Control and Prevention (CDC) named it a “variant of concern,” including:
We know the vaccines we have today are effective against COVID-19 and that they appear to work against the delta variant, as well. That’s good news if you’re fully vaccinated, but it could mean trouble if you aren’t. More than 95% of the people who end up in the hospital with COVID-19 now are unvaccinated. And among those who die from the virus, the percentage who didn’t get a vaccine is even higher. As the director of the CDC recently noted, “This is becoming the pandemic of the unvaccinated.”
Currently, everyone 12 years and older is eligible to get a COVID-19 vaccine in the U.S. But as of late July, less than 60% of that population are considered fully protected. This means there are still many Americans at risk from the delta variant.
To be fully protected, you must:
If you’re not vaccinated — or not yet fully protected — it’s best to:
Concerned about the vaccines? Talk to your doctor.
The more people who get vaccinated, the less of a threat the delta variant poses.
With higher vaccination rates, it also becomes less likely that other, potentially even more dangerous variants will emerge.
There are a lot of rumors going around about the vaccines. Don’t let them keep you from protecting yourself and the people you care about. Vaccines are safe, and they work. If you have questions or concerns, it’s best to talk to your doctor. No vaccine is 100% effective, but there’s no doubt they save lives. And while side effects are possible, serious complications are extremely rare.
Know the symptoms of COVID-19
COVID may present with a variety of symptoms, including:
People with the delta variant also frequently report:
If you think you could have symptoms, the CDC offers a coronavirus self-checker. It can guide your decisions about getting tested and seeking medical care.
Remember, you have the power to help defeat COVID-19 by getting vaccinated. Protect yourself and help protect others.
