A U.S. disease expert says COVID-19 survivors may expect to be immune from another case for as long as one year.
Former Food and Drug Administration official Dr. Scott Gottleib appeared on CBS’s Face the Nation Sunday to talk about new findings by the Centers for Disease Control and Prevention that say a three-month immunity is a certainty.
“But it’s probably the case that you’re going to have a period of immunity that lasts anywhere from six to 12 months. It’s going to be highly variable. Some people will have less immunity, some people will have slightly more. But it’s good news that they’re able to document that people have really sterile immunity. They’re not going to get reinfected for at least three months and probably longer than that after infection.”
But Gottlieb cautioned that the COVID-19 is called the novel (new) coronavirus for a reason – there is still much that doctors don’t know about it.
14 States Make Contact Tracing Data Public
When everyone who tests positive for coronavirus in your community gets a call from a public health worker asking them about their contacts and those contacts are then asked to quarantine, the process creates a powerful way to keep the virus from spreading.
But contact tracing can do more than that: At scale, the data gathered in those calls also offers vital information about where transmission is happening in a community. That data can drive policy and even guide individuals in assessing what’s more or less safe to go out and do.
NPR has surveyed the health departments of all U.S. states and territories three times about contact tracing capacity — first in April, then again in mid-June, and most recently in late July. The latest survey, done in collaboration with the Johns Hopkins Center for Health Security, also asked states about contact tracing data: what they were gathering and what they’re making public.
