今天的小獭堆了一个雪人⛄，本想给雪人装玉米烟斗和胡萝卜鼻子的，但是堆到一半突然肚子饿了，所以它的雪人看起来就有点……你开心才最重要，小獭！！ #海獭[超话]#

President Joe Biden tested positive for Covid-19 again Saturday morning, per a letter from presidential physician Dr. Kevin O'Connor, in what is likely a "rebound" Covid-19 positivity that the doctor noted is "observed in a small percentage of patients treated with Paxlovid."
Biden has experienced "no reemergence of symptoms, and continues to feel quite well" and will, as a result, not resume treatment, the White House said. O'Connor said the President tested negative on Tuesday evening, Wednesday morning, Thursday morning and Friday morning before testing positive on Saturday morning.
"However, given his positive antigen test, he will reinitiate strict isolation procedures," the doctor noted. Biden ceased isolating on Wednesday after testing negative on successive antigen tests, celebrating his return in remarks from the White House Rose Garden.
