When I came back from a California trip to my hometown in Mexico, I got something nasty with the typical symptoms: fever, shortness of breath, dry cough, etc etc. I went to the ER and got x-ray and blood samples.

When my doctor arrived, he was all cool. Then he asked me a bunch of questions and went to see the x-ray and blood work result in the labs. After taking some time, when he came back, he had a face mask and a can of Lysol. He said he had been delayed filling an epidemiological report.

That's the moment when I knew it was bad haha.

Another for the list: "Do you know how high your heart-rate was?" (said with childish glee).
