A few days after Amyiah Cohoon returned to Wisconsin from a school band trip to Florida in the middle of March, she developed a dry cough, a high fever and breathing problems. Amyiah, 16, was taken to the hospital twice, before being sent home and told to stay inside despite testing negative for the coronavirus.

During her sickness, the Westfield Area High School sophomore posted on Instagram three times about what she still believed was a scary brush with Covid-19, hoping to alert others, including friends and family, to the danger. (Doctors have noted that negative results did not always mean someone was not infected.)

“I am still on breathing treatment but have beaten the coronavirus,” Amyiah wrote in the third post on March 26. “Stay home and be safe.”

The next day, a sergeant showed up at the Cohoons’ door.

According to a police report included in the lawsuit, Amyiah’s posts had made other parents at school “upset.” Amyiah would have to take the posts down or risk violating rules on disorderly conduct and be cited or arrested, according to the report.
