Nothing can stop Khloé Kardashian.

The reality star gave fans an update on her staph infection on Tuesday, telling her 17.2 million Twitter followers that she’s reached a major milestone in her recovery.

“I’m so blessed I’m doing better and my infection is healing,” the reality star tweeted. “I was able to be out and about today… Quarantine is over lol.”

Kardashian, 31, announced her illness when she canceled signings of her book Strong Looks Better Naked last week. “I’m sick & dr’s orders are that I need to lay low until we narrow down what’s wrong.”

A source previously told PEOPLE that she was infected while at the bedside of her estranged husband, Lamar Odom, during his ongoing recovery at Cedars-Sinai Medical Center, where he is recovering from an October health crisis.

Although Kardashian is now able to “be out and about,” she is still not permitted to visit Odom in the hospital until she is fully recovered.

“Khloé is devastated that she can’t go to the hospital and visit Lamar,” a source close to the Keeping up with the Kardashians star tells PEOPLE in this week’s issue. “That’s the thing that is bothering her most about the infection.”
