Joseph’s mother, Sabrina Bostain, posted about her son’s diagnosis on March 19, after it was confirmed, asking her Facebook friends for prayers and to adhere to social distancing guidelines.

His early symptoms included a fever, cough and fatigue, she wrote.

In the two weeks that followed, Bostain posted regular updates on his condition and thanks for the gifts and care packages people had shipped to her son.

By March 28, his fever had broken for good, she wrote.

“Every day is a better day,” she wrote on Sunday. “Joseph had a wonderful night’s sleep and [is] still fever free. Thank you God!”

Finally, on April 1, she posted a video with the caption: “Today Joseph can tell you how he is doing himself!”

Bostain and her husband, Timothy, have five children, according to her Facebook profile.
