Doctor is a condom 100% safe protective from HIV?
Nothing in this world is 100% safe. There are no guarantees.
In the laboratory, condoms have been shown to be impermeable to viruses and other organisms. However, in the real world many things can go wrong with usage of condoms. The condom may not be used properly. It may be removed too early. It may break during sexual intercourse. It may be reused. All these factors mean that in real life, condoms are estimated to be about 80% effective against HIV.
The best way to prevent transmission of HIV is for the infected partner to take medication (ART) and to use condoms each time they have sex.
