It would be crazy if this turns out to be the verified cause. I visited Cuba right before the Obama trip, 2015 I think. There was great fear of the Zika virus at the time. The mandatory national spray program was in full swing, and in fact came into the guest house where we were staying, ran everyone out side, and then heavily fogged the entire property. As they did to each and every house in Havana, and all across the country. The piece of equipment that they were using looked like it came from the 1950’s, made of tin and all dented, with a tiny gasoline (or kerosene) engine, and a cone like a cartoon drawing out of which the poison fog spewed.
No ringing in my ears yet, though…so far.
