TRENTON, N.J. (AP) — HIV testing will soon become part of routine prenatal care and be required for some newborns in New Jersey under a new law that supporters say is putting the state in the forefront of the national fight against HIV transmission to babies.

Acting Gov. Richard J. Codey signed the measure into law Wednesday at University Hospital in Newark. The law will take effect in six months.

"We can significantly reduce the number of infections to newborns and help break down the stigma associated with the disease," Codey said.
