The family considered quarantine to be "dishonourable" and contrary to "customs and traditions" that do not allow women to stay out of their family home without a chaperone.
Ali Al-Bayati, a member of the Iraqi High Commission for Human Rights, confirmed the existence of cases where families refused to let hospitals quarantine their daughters to preserve their "honour", according to reports.
Al-Bayati added that some families have even organised demonstrations outside hospitals that quarantine coronavirus patients.
Iraqi social media users have condemned the trend, with some used an Arabic-language hashtag that translates to "epidemic of ignorance".
A Twitter user reported an alleged incident in the Iraqi city of Najaf, when a family attacked health workers to stop them from quarantining their daughter.
The family is also said to have accused the medical staff of wanting to rape her.
"God damn family honour," another user tweeted.
Local journalist Amer Ibrahim stated that there is a trend among Iraqi women to conceal their coronavirus-positive status.
Iraq reported 316 coronavirus cases and 27 deaths.
