Five residents of northern Tel Aviv, all above the age of 60, were hospitalized in the past two weeks at the Sourasky Medical Center in Tel Aviv after contracting West Nile Virus, as reported by the Jerusalem Post. 

Three of them are in serious condition and are hospitalized in intensive care.

Dr. Yevgeni Katzman, an expert in internal medicine and infectious diseases at Ichilov Hospital, said that all the patients are from the Ramat Hachayal and Shikoun Dan Tzalah areas. They are all [typically] healthy, active individuals in their seventies. This is an outbreak, so it's important to warn the public. In all my years as a doctor, I have never seen so many patients hospitalized simultaneously due to this disease.”
