What is percentage risk of hiv infected mother infecting her baby?

The risk of a mother with HIV (human immunodeficiency virus) transmitting the virus to her baby during pregnancy, childbirth, or breastfeeding depends on several factors, including the mother's viral load (the amount of HIV in her blood), whether she receives antiretroviral therapy (ART), and whether she breastfeeds her baby.
According to the World Health Organization (WHO), without any interventions, the risk of mother-to-child transmission of HIV during pregnancy, childbirth, and breastfeeding is estimated to be around 25% to 45%. However, with proper interventions, such as ART during pregnancy and breastfeeding, the risk of mother-to-child transmission can be greatly reduced.
In countries with access to ART and effective prevention of mother-to-child transmission (PMTCT) programs, the risk of mother-to-child transmission can be reduced to less than 2%. In such countries, healthcare providers may also recommend elective cesarean delivery (C-section) for women with a high viral load to further reduce the risk of transmission during childbirth.
It's important for pregnant women with HIV to receive early and regular medical care, including ART and PMTCT services, to reduce the risk of transmitting the virus to their baby. If you have questions or concerns about HIV transmission during pregnancy or breastfeeding, it's important to speak with a healthcare provider.
