The Latest: “Flatten the curve” is back

Dear Reader,

As I’ve shared with you, I am hopeful about the Covid-19 vaccines currently under review. But I am very worried about what’s happening right with Covid-19 cases. Infection rates are increasing at record-breaking levels, which means hospitalizations and deaths are likely to follow.

But it’s important to reiterate that a vaccine isn’t needed to keep cases low. Remember when the slogan of the pandemic was “flatten the curve”? As Dr. Theresa Chapple recently shared on Twitter, a bleak winter does not have to be inevitable. There are specific things you and your loved ones can do to prevent infection, like wearing masks, distancing, and reconsidering indoor activities. What was relatively safe in the summer is less safe right now.

This is really hard and fatiguing. My family will not be spending Christmas together for the first time ever and I am very sad about it. But it’s worth it. As Andy Slavitt recently wrote:

The CDC’s new quarantine guidelines. The U.S. Centers for Disease Control and Prevention (CDC) has updated their quarantine recommendations, offering people the options to isolate for seven or 10 days instead of two weeks after a potential exposure to the coronavirus. The shorter timelines require that people have no symptoms and continue to wear a mask for the full 14 days. The one-week quarantine also hinges on a negative test after at least five days post-exposure, Dana Smith reports. Read more.

What the world can learn from Africa’s Covid-19 response. Where the U.S. has floundered in its handling of the pandemic, several African countries have succeeded. Tiffany Onyejiaka reports on the many lessons from Africa’s response, including the idea that if you stay ready, it takes less to get ready. Read the other lessons here.

Kids likely won’t be in the first round of vaccinations. Clinical trials for a Covid-19 vaccine for children are only just beginning. Most kids will not be vaccinated until later in 2021. Is this OK? Jesse Smith reports that children, particularly infants and toddlers, have immune systems that are highly reactive and you cannot assume a child will react to a vaccine in the same way as an adult, so special trials are needed. “The delay in validating a Covid-19 vaccine in children is intentional, and an important step in creating a vaccine that is safe for all groups of people,” he writes. Here’s more.
