It’s leading up to National HIV Testing Day on Sunday.Spokesperson Kathy Harrison says national health organizations estimate some 200-thousand people in the U.S. are HIV positive and don’t know it.“The earlier you find out, the better, because with treatment and care, you can live a longer and healthier life," says Harrison.
