can herpes simplex type 1 turn into type 2?

No: Herpes type 1 and type 2 are different viruses. They don't mutate into one another. A person can get both types. Either or both types can occur on the genitals or orally. For example, if a person has both types orally, sometimes a lip sore will be type 1 and other times it will be type 2.

No: Both are completely different strains. Type 1 causes lesions typically around the mouth. Type 2 causes lesions typically around the genitals. However, there are no absolutes in medicine so either strain can occur anywhere.
