Hello, I was just wondering what the most common method of transmission was. I got it from my sister who got it from primary. I'm dreading the idea and want to prepare. Is there a season for chickenpox? NHS writes that you typically would require 15 minutes or more of contact? I figure it might be better to ask for personally experiences. My child is 2 and stays home so I assumed relatively low risk until my brother said that you can get it from someone in line at a shop. I will gratefully take any advice available
