So, if “Patient Zero’s” family had taken a little better care of him...
First of all, they weren’t his family, were they. She had not married him and I think their last physical contact was in the refuge camp where he impregnated her. His family was in another state.
I think his family had lived with the mattress, etc., and went about their lives outside of their apartment, asking for things to be taken away, but I do not remember them asking how they could decontaminate the place themselves.
As for taking care of him, it looks like instead they want to be “taken care of” for the rest of their lives, and are using this as an opportunity to press their race grievances, rather than be grateful and help prevent other West Africans from coming over.
