Can condom fully prevent HIV spread ?

HIV hides inside the DNA of healthy T cells, a place where current medicine is unable to reach it. While most T cells die shortly after becoming infected, a small portion of T cells containing the instructions for creating the virus remain dormant. This means that even if the virus is completely eliminated from the body, at any given point the instructions for creating the viruses could activate and start the process all over again.

HIV infects a kind of white blood cell called a CD4 lymphocyte, a key player in the immune response. What makes HIV so sneaky is that it infects the very cells that are supposed to rub out viral infections.

HIV replicates in CD4 cells when they are activated -- that is, when they are triggered by an infection. But some HIV-infected cells become inactive before the virus replicates. They go into a resting mode -- and the HIV inside them becomes dormant until the cell is activated.

Anti-retroviral drugs don't affect HIV hiding in resting cells. These cells represent a hidden reservoir of HIV. When treatment stops, the resting cells eventually become active. The HIV inside them replicates and quickly spreads. That's why current HIV treatments don't cure HIV.

It is a virus that expands and multiplies using the body's immune system. The immune system works to tackle the virus, but the more it does this, the more HIV is able to replicate. Over time – usually many years – without treatment, the virus always comes out on top.

The second challenge for HIV drugs and vaccines is that the virus has a very high turnover – billions of copies every day in a person who is not on treatment – and makes small errors or mutations which can lead to the easy development of drug resistance.

Condom when used well can help,but abstain from sex or have one sex partner to be safe.

 

Not that I'm aware of. Nothing is full proof though. Condoms aren't even 100% effective on protecting against unwanted pregnancies. If you suspect someone you are having relations with have HIV or AIDS, your best bet is to get them and yourself tested quickly. A certified professional will tell you how to better protect yourself and your partner against HIV or AIDS. But, there is no concrete evidence to suggest condoms prevent the transfer of HIV or AIDS or any STD for that matter. Good luck.
