I suspect that we will see more of these types of actions over time. With that in mind, please consider your own house. Are you able to “shelter in place” for 3 weeks? If not, better get stocked up.
In addition to food and water storage, consider the following items:
Bleach / Pool shock for disinfectant
Surgical masks
Nitrite gloves
Hand sanitizer
Extra trash bags
UV wand
