What is the viral load required for giving birth a normal baby by a hiv+ ve women? and what level of cd4 count should be there for the above need?

This is a controversial and very complicated topic and best explained by an expert obstetrician trained in high risk delivery such as HIV infected pregnant women. In general the higher the viral load, the greater the risk of tranmission to the baby. There are exceptions (i.e. no transmission with high viral load and transmission with low viral load). It is also affected by whether the mother is already on active HIV treatment and becomes pregnant, or starts treatment during pregnancy, or just gets HIV meds at the time of delivery. Cesarean section versus natural vaginal delivery can also affect neonatal infection rates. Higher CD4 counts also can affect transmission rates.
