If his report of no other partners besides you and his wife is accurate and he is negative at 10 weeks then you should be just fine, yes. The ELISA does become positive more quickly than the western blot – I like 16 weeks for that one – so you should feel fine about this. Also, your symptoms are not those of herpes with your full body itching, random rashes on arms that come and go. Herpes affects the area of encounter – like genital – not full body symptoms. I feel that you are very likely worrying way too much and that neither you nor your partner has anything to worry about. I don’t believe that you need to retest, no.
