The Ministry of Health says it is investigating several cases of suspected leptospirosis, also known in Hebrew as Achberet since it is spread by small rodents, according to the Israel Public Broadcasting Corporation.
The source of the disease is probably the source of water in the Golan Heights. Since Thursday, seven people have been treated at Shaare Zedek Hospital in Jerusalem on suspicion of having contracted the disease. According to Wikipedia, If the infection causes the person to turn yellow, have kidney failure and bleeding, it is then known in English as Weil's disease. If it also causes bleeding into the lungs then it is known as severe pulmonary hemorrhage syndrome.
