An Australian teenager who partied while positive is charged with ignoring health orders.

A 19-year-old man who kept partying at a nightclub in South Australia despite being notified that he had tested positive for the coronavirus was charged with failing to comply with public health orders, the police said on Tuesday.

The health authorities told the man on Dec. 17 that he had tested positive, but he “remained at a city nightclub and did not quarantine,” the police said in a statement.

The man, who was not identified, stayed at the nightclub in Adelaide until the morning hours, according to local news reports. More than 100 patrons and staff members of the nightclub were forced into isolation because they were considered to have been in close contact with him.

He faces a maximum penalty of two years in jail or a fine of up to 20,000 Australian dollars, about $14,500. He was released on bail and is expected to appear in court in February.
