Can HIV be transmitted through shared personal items like razors?

HIV can indeed be transmitted through shared personal items like razors if they come into contact with contaminated blood. When a razor is used by someone with HIV, their blood can be present on the blade. If another person then uses that razor and it causes cuts or nicks in their skin, the virus can enter their bloodstream and potentially lead to an infection. This transmission method, while less common than others such as sexual contact or mother-to-child transmission, is still a valid route for the virus to spread.

In contrast to the other options, it's important to note that while sexual transmission is the most common way HIV spreads, the virus can survive outside the body for a short time. Thus, the idea that it can only be transmitted through sexual contact or from mother to child overlooks the potential risk associated with shared personal grooming items. The assertion that HIV cannot be transmitted outside the body fails to recognize specific scenarios, such as the use of razors or needles, where contact with infected blood poses a risk.
