 [ Symptoms ] can adderall cause nausea [ Disease ] hi ok it seems if you already have one type of hsv it is harder to get the other type that is because the virus causes the body to produce antibodies that provide some crossover protection against the other type should it entering the body that is why when a person with a prior hsv infection does contract the other type the first episode tends to be less sever than in a person who has no prior antibodies hope this helps you good luck
