Poor thing. Yes, you gave good advice. Her BF needs to know. He might even want to consider the vaccine.
Isn't HepB treatable? Vash might know. I know there are acute & chronic conditions. I also know that superinfection w/the hep delta virus makes for a much more serious condition, so she should discuss w/her doc (I'm not an MD but I know about molecular biology of viruses).
Does she know about Medline? Tell her to find out more there:
