Do condoms always prevent the transmission of HIV?

Condoms significantly reduce the risk of HIV transmission, but they are not infallible. There are circumstances where some transmission can still occur, such as if the condom breaks, is damaged, or is not used properly. The effectiveness of condoms also depends on consistent and correct use; even minor lapses can lead to exposure to the virus. While well-constructed latex or polyurethane condoms can provide a high level of protection when used correctly, they cannot guarantee complete prevention of HIV transmission in every situation. Hence, it's essential to pair condom use with other preventive measures, such as regular testing and communication with partners about HIV status.
