It still doesn't change how you should approach such a threat. Waiting until the authorities declare an emergency to prepare is silly.
1. Fear is the worst emotion you can employ to deal with any threat
2. Your innate immune system is powerful & adaptive if it is not suppressed by toxic crap
3. Being resilient to the breakdowns in the supply of food, water, energy & basic necessities (eg soap, toilet paper) is useful
4. Being away from densely populated areas or being able to withdraw from them quickly is useful
5. Having anti microbial tools available should you or your loved ones be infected is useful. Colloidal silver, ivermectin, antibiotics, iodine & chlorine dioxide are all useful in many situations to varying degrees.
