The vast number of outbreaks of tension on the planet shows that it is impossible to underestimate the preparation level of population protection in emergencies. The possibility of a terrorist attack, including the use of particularly toxic or biological substances cannot be excluded or totally prevented at this point. In fact, there may not only be a terrorist attack. Rampant population migration increases the risk of the transmission of infectious diseases, even to considerable distances from the states where the epidemiological situation might not be completely under control. The current state of the Czech healthcare system in terms of preparedness for mass emergencies is insufficient and requires prompt correction, though not through hastily adopted measures. Ideally, looking into the success of the Israeli preparedness system, where the public has been exposed to high levels of threat from a variety of causes for decades, could greatly aid the Czech Republic in moving forward effectively. The number of victims of terrorist attacks there outpaces 10000, a fact that shows Israel is experienced in responding to emergency incidents.
