Which of the following route will NOT aid the transmission of STIs? Blood transfusionPerinatal transmissionSkin to skin contact Unsterilsed use of drug needles

The route that will NOT aid the transmission of STIs (Sexually Transmitted Infections) among the options provided is "Skin to skin contact".

Here's why:

1. Blood transfusion: If the blood being transfused is infected with an STI, it can be transmitted to the recipient.

2. Perinatal transmission: This refers to the transmission of diseases from mother to child during the period immediately before and after birth. If the mother has an STI, it can be transmitted to the child.

3. Skin to skin contact: STIs are typically transmitted through sexual contact, not casual skin to skin contact. Therefore, this route will not aid in the transmission of STIs.

4. Unsterilized use of drug needles: Sharing needles can transmit STIs, especially if one person is infected and the needle is not sterilized before being used by another person.
