Five hundred army recruits were given an unexpected holiday leave this week after the Israel Defense Forces Medical Corps ordered a quarantine following a fast-spreading outbreak of a serious lung infection. IDF sources said that training at the base was expected to restart next week after more medical tests. The public health branch of the Medical Corps tried to isolate the cause of the outbreak, but it has yet to be determined. Fourteen soldiers from the base were hospitalized after contracting the infection. The soldiers initially complained of breathing problems and fever.
