5. How HIV-positive women can give birth to a child A healthy baby that is not HIV-infected


The answer is: mother-to-child blocking. The risk of mother-to-child transmission without intervention can reach 20%-40%.

Under the scientific guidance of professional doctors, it is entirely possible for HIV-positive women to give birth to a healthy baby that is not infected by HIV.

Mother-to-infant blocking technology mainly includes the whole process of guiding infected persons to detect and antiviral treatment before, during and after pregnancy, selection of delivery methods, scientific feeding, newborn detection and preventive antiviral treatment.
