There's a saying to the effect of "never attribute to malice that which can be explained by stupidity", and perhaps that applies here. It seems likely there's some kind of link between incidents and it's surely not "mass psychosis". The link could just be something as simple as a bureaucratic requirement for a certain product to be used by/for US personnel; maybe a particular pesticide, or maybe some cheap office supply-type product. Or maybe it really is the Russians attempting to spy and there's a glitch with their devices. Making the people you are spying on sick and thus drawing attention isn't really the goal after all.
