June 25, 2020 -- With COVID-19 cases rising in younger Americans, the CDC had a clear message for all adults Thursday: When it comes to age, there’s no bright line for risk.

“There’s not an exact cutoff of age at which people should or should not be concerned,” Jay Butler, MD, said at a news briefing. Butler is the CDC’s deputy director of infectious diseases.

After analyzing cases across the U.S., the CDC announced updates to the characteristics that seem to leave people vulnerable to the worst COVID-19 outcomes: hospital stays, intensive care, and death.

For starters, it got rid of the age category “65 and older.” Instead, under the tab “People Who Need Extra Precautions,” there’s a category called “Older Adults.”

The page now explains that risk from a COVID-19 infection increases with advancing age. In general, people in their 50s are at a higher risk than people in their 40s. Likewise, people in their 60s and 70s are at a higher risk than those who are in their 50s.

“We know that risk is a continuum. It’s not just risk to those ages 65 and older,” said CDC Director Robert Redfield, MD.

The CDC has also updated the list of health conditions that make a person more likely to have severe outcomes from COVID-19.

Conditions in which there’s strong evidence of increased risk include:

Conditions that might place a person at a greater risk for a severe outcome from COVID-19 are:

The revisions call into question the role of high blood pressure (hypertension), which was flagged early on as a risk factor among severe cases in China. About 50% of American adults live with high blood pressure.

Butler said hypertension had been moved to the list of conditions that could place a person at increased risk because they had learned more about the role of hypertension, on its own, and some of the things that hypertension can lead to, like kidney damage and heart disease.

“We’ve been able to tease apart a little more how much just having hypertension alone, as opposed to having some of those end-organ manifestations of hypertension, might be driving the increased risk,” he said.

Obesity, in contrast, seemed to be its own, independent risk, even apart from other health conditions that may also happen in people who are obese, like diabetes.

Finally, a new study by the CDC showed that pregnancy can make the course of COVID-19 more severe for women, though it doesn’t seem to increase their risk of death.

In a study that compared COVID-19 outcomes among women between the ages of 18 and 44 by pregnancy status, nearly one-third of the pregnant women were hospitalized for their infections, while only about 6% of the non-pregnant women had to be admitted to the hospital. Pregnant women were also more likely to need ICU care and to receive breathing support from a ventilator, but they were not more likely to die. About 0.2% of both pregnant and non-pregnant women died of COVID-19 during the study period.

Study authors stress that women who are pregnant during the pandemic should take extra care by staying at home whenever possible, wearing a mask in public, standing or sitting at least 6 feet away from others when they do have to go out, and washing their hands often.
