Aids researchers are studying a program they say could end the HIV pandemic within 50 years.
Leaders from the National Institute of Allergy and Infectious Diseases call the global program 'test and treat.'

They propose starting universal, voluntary and annual HIV testing and beginning immediate treatment for those who test positive.

Using this model, they predict HIV incidence could drop from 20 new cases per 1,000 people to less than one new case per 1,000 people each year.

Right now 33 million people worldwide are infected with HIV.

In other health news, taking multi-vitamins during pregnancy may reduce the risk of delivering a baby with a low birth weight.

Right now, the world health organization recommends pregnant women take an iron-folic acid supplement instead of a multi-vitamin.

But a new Canadian study finds multi-vitamins reduce low birth weights by 17% which is more effective than iron-folic acid supplements.

Researchers say 1.5 million babies born with a low birth weight could be avoided each year, if mothers get and take these prenatal multi-vitamins.
