I came home from TJ Friday night. I'm 3000 miles there and 3000 back. Lots of planes, people etc. On Monday the 27th the first mask I saw was in TJ where a few locals wore them. I did put one on in the hospital as instructed for precaution but mainly staff wore them only. You are not out in the gerneral public shopping but it truly is overhyped. By Friday when i came home I never seen a mask anywhere. San Diego Airport is right there and not one to be seen by staff, travellers, families or the elderly. I was also at the airports in Pensilvania, St.Paul MN, Detroit and Syracuse NY and saw nothing of concern by staff or travellers wearing masks etc. It's making bigger news elsewhere is all I know. Myself and friend that came with me are fine. I was truly more concerned about the filthy airflow controllers overhead on the plane and the airline stewardess who coughed in her bare hand and then served a drink and did it agin with the other hand. I believe it was a tickle in her throat but you NEVER cough in your hand. She should know this OMG.
I was told that the original amount of deaths in Mexico originally 100+ ? ended up at 12. I believe they are assuming and not actually testing, then once tested find it's not that at all. Obviously if you have concerns you must do what feels right for you. This was just my experience this week at the MX border and TJ. Hope it helps.
