During a phone interview with Xinhua news agency, Lu made an apology for going to varies public places after developing flu symptoms, saying he did not know he had the A(H1N1) flu.

The spokesperson of the Health Department of Shandong province said prior to Lv's discharge quarantine for the 38 people, who were exposed to him, was lifted at around 10:30 pm Monday.
