The Human Necrotic Fugue Virus outbreak centered on a homeless shelter in Redwood City had just ended. r/BayArea covered the story, and blamed it on a combination of a spider, human negligence to do with cleaning products, and unethical human sexual activity. One expression they used was “perfect storm”. Given the simple fact that they and the spider were all there, they had committed every mistake set advice on how to not get infected with Human Necrotic Fugue Virus always warned people against. It’s not any one factor that caused the outbreak, instead their mistakes but together were a [“necessary” and sufficient condition](https://en.wikipedia.org/wiki/Necessity_and_sufficiency) for the sexually transmitted version the shelter clients and staff carried it in their blood to combine with the animal-borne version the spider bit them with. I didn’t really consider that to be necessary, but I know that’s not what they meant.
