Hello! I have been through your question. According your concern I think you should know that HIV is treated using a combination of medicines to fight HIV infection, called antiretroviral therapy (ART). ART isn’t a cure, but it can control the virus multiplying so that your daughter can live a longer, healthier life and reduce the risk of transmitting HIV to others. Your daughter must take this treatment every day for all life, exactly as prescribed by her doctor. HIV medicines prevent HIV from multiplying (making copies of itself), which reduces the amount of HIV in the body and give your daughter s immune system a chance to recover and fight off infections and cancers. ART is recommended for all people with HIV, regardless of how long they’ve had the virus or how healthy they are. If left untreated, HIV will attack the immune system and eventually progress to AIDS.If your daughter don’t take regularly HIV medications exactly as directed, she could develop drug resistance, which could make HIV medication (ART) stop working.It is important to be aware that ART is a lifelong treatment that can keep your daughter healthy for many years and greatly reduce the chance to transmitting HIV to the others. When to start ART depends on some factors like CD4 count and other test results of your daughter, if she has any other diseases or conditions ( including pregnancy, an HIV-related illness), or AIDS (AIDS is the most advanced stage of HIV infection) and ability and willingness to commit to lifelong treatment with HIV medicines. Furthermore, according these factors, above mentioned is the HIV/AIDS specialist that decide when and what kind of ART regimen should start your daughter. What I suggest is that you should support your daughter in every social and health problem that she could have during her life living with HIV infection. I hope my answer help you. I wish your daughter good health.
