Former New Jersey Gov. Chris Christie is spending his fifth day in the hospital after contracting COVID-19, but he’s in good spirits and under good care, a source with knowledge of the situation confirmed to NJ Advance Media.

Christie’s exact condition remains unknown. The 58-year-old has not tweeted since Saturday, the day he announced he tested positive for the coronavirus and checked himself into Morristown Medical Center.

Christie’s stay is currently in line with an average COVID-19 hospitalization. Five days is the median length of hospital stays for coronavirus patients outside of China, according to an analysis of 52 studies published last month in BMC Medicine.

Meanwhile, the source, who asked for anonymity to speak candidly about the matter, shot down a rumor that bounced around social media Wednesday morning that Christie was on a ventilator.
