Brief Answer: No need for HIV test, syphilis is positive Detailed Answer: Hello, Thanks for posting your query on XXXXXXX HIV infection is transmitted by three routes- sexual route, infected blood and from infected mother to the baby. High risk sexual behavior - having multiple partners, having unprotected sex and having sex with an infected person. Kissing and biting can transmit infection if your partner is infected and there are presence of erosions on the skin. It is unlikely from your history that transmission of HIV would have occurred. There months period after exposure is called window period. During this period the test comes out to be negative even if the HIV infection is present. In order to be 100 % sure, you can get An ELISA done after three months of the sexual act i.e. in December. Regarding syphilis, VDRL which is a sensitive test for syphilis is only weakly positive and TPHA is positive; these test results are suggestive of syphilis infection. You need to consult your doctor and take treatment for the infection. If you have more queries, I will be glad to answer Dr Shailja P Wahal
