In the UK the non disclosure of HIV goes toward an assault, In R v Konzani the UKCA held that non-disclosure of HIV vitiates the consent to running the risk of HIV. The judge said regarding consent informed consent is required. So they upheld the reasoning in Dica.
In regard to it being rape the statutory wording in the sexual offences Act 2003 it says intentional depiction as to nature and purpose. In Dica in obiter they talk about how it does not vitiate consent to sex, as the consent was full and conscious, and R v B makes the dica obiter binding. Although you do have to be careful as the act states intentional deception, so it is possible that non-disclosure would fall within this earlier category in these cases. Although the reasoning is based more on interpreting nature and purpose rather than assessing whether it was an intentional deception.
If you wanted you could compare with Canada, depending on what type of question it is.
