Will I Get the Mexican Deadly Flu B/C I Talked To Someone Who Went To Mexico?

I had a end-of-the-year soccer party today and my mom drove one of my friends home. She was with us in the car for about 15 at the most.
Every few minutes, she would cough. Assuming it was a simple cold, we went on driving but then we got on the topic of this flu and she said that she went to Mexico about a month ago.

Now, my sister was sitting beside her and my mom and I were up front. We all washed our hands after and breathed fresh air but does this mean that she has it and that we’ll get it?? I’m so worried .
