In this reality that greatly diverges from our own reality, Israel of this reality has a leading national public health agency called the Israel Sanitary Surveillance Institute that's slightly more technologically equipped and advanced in this reality.
Prior to the outbreak
Prior to the near-global outbreak of the mysterious disease from the stars, the Israel Sanitary Surveillance Institute was the leading national public health agency of Israel that answered to the orders to the Ministry of Health. It was slightly more technologically equipped and advanced than some of its counterparts is some parts of the globe. It also had some sort of secretive international relationship with the United States Centers for Disease Control and Prevention to the point that in case their United States counterpart has failed in stopping a global pandemic from happening, then all data and information of a said virus or disease would transferred to the Israel Sanitary Surveillance Institute as well as samples being brought to it as well.
During the outbreak
Around several days after the near-global outbreak had begun in Lead Hill, Arkansas, the United States Centers for Disease Control and Prevention began to fail in stopping an organoboron extraterrestrial pathogen that was, somehow, reanimating its victims to become cannibalistic monsters with an unstoppable urge to keep feeding on something, alive and warm. The United States Centers for Disease Control and Prevention began to send all of its data and information as well as complete samples of the mysterious virus from outer space. At first, they began to quit with the three weeks after the near-global outbreak was spreading to both Canada and Mexico's borders, but soon the nation-wide military lockdown began. It was therefor, that scientists had to go back to work at the Institute.
