"Kenzie was complaining about a really bad headache and then they took her temperature and she had a fever," she said.
After taking her to Brooke Army Medical Center, doctors tested her for flu, strep and Covid; only the last one came up positive.
"The doctors told my sister-in-law take her home and to make her comfortable, to monitor her fever, and if it got over a certain point, or if there were any other major issues that occurred, to go ahead and bring her back to the hospital," another aunt Erica Gongora told Today.
"There was no labored breathing or anything like that, at that point."
Makenzie had no underlying health issues that the family knew of; aside from being a little small for her age, she was in perfect health.
The family kept a close watch on her all weekend, where her symptoms ebbed and flowed, but never became any more serious.
But on Monday February 1, Makenzie told her parents she felt really tired, and went to bed early.
