Introduction
In general, correct use of condoms can largely prevent the transmission of HIV. However, their effectiveness depends on consistent and correct usage. When selecting condoms, choose reputable brands to ensure quality standards are met. Check that the packaging is intact and that the product is within its expiration date before use. Use proper techniques when putting on a condom to avoid tearing it with fingernails or sharp objects.

Generally speaking, correct use of condoms can largely prevent the transmission of HIV/AIDS. However, their effectiveness depends on consistent and correct usage. A detailed analysis is as follows:

If high-quality condoms are used correctly and consistently throughout every sexual act, and there are no incidents such as breakage or slippage, they can effectively prevent the transmission of HIV/AIDS. Condoms provide a physical barrier that isolates genital secretions, preventing the virus from spreading through bodily fluid exchange. This method effectively interrupts the primary transmission routes and reduces the risk of infection.

If condoms are not worn throughout the entire sexual act, if the size is inappropriate leading to slippage, or if the condom is damaged or expired, the effectiveness of preventing HIV transmission will be significantly reduced. The virus may enter the body through contact with bodily fluids, increasing the likelihood of infection, especially when condoms are not used consistently every time, which poses a higher risk.

When choosing condoms, it is important to select reputable brands and ensure product quality. Before use, check whether the packaging is intact and the product is within its expiration date. Proper usage techniques should be followed to avoid puncturing the condom with fingernails or sharp objects. After sexual intercourse, the condom should be removed promptly to prevent semen leakage. Additionally, condoms alone should not be relied upon as the sole prevention method. Combining them with other preventive measures, such as regular testing and avoiding multiple sexual partners, can comprehensively reduce the risk of infection.
