Under Quarantine is the riveting story of Shaar Ha'aliya, a central immigrant processing camp opened shortly after Israel became an independent state. This historic gateway for Jewish migration was surrounded by a controversial barbed wire fence. The camp administrators defended this imposing barrier as a necessary quarantine measure - even as detained immigrants regularly defied it by crawling out of the camp and returning at will. Focusing on the conflicts and complications surrounding the medical quarantine, this book brings the history of this place and the remarkable experiences of the immigrants who went through it to life. Evocative and bold, Under Quarantine shows that we cannot fully understand Israel until we understand Shaar Ha'aliya. The gate of arrival for nearly half a million immigrants - a space of homecoming, conflict, exclusion and welcoming - here was the country's crucible.
