On February 16, 2006, Hu was detained for 41 days. His detention was not acknowledged by the Chinese government. After his return to his apartment in Beijing, where he lives with his wife Zeng Jinyan (also an AIDS activist), Hu Jia was kept under house arrest until March 2007.

Hu Jia has remained active via emails and blogs while under house arrests.
