Seattle Children's Bellevue clinic discovered surgical tools that may have been contaminated, and more than 3,000 children and teens were tested for HIV and hepatitis, according to The Seattle Times.
Here are five key facts:
1. Warnings sent to 12,000 patients prompted many to get tested.
2. So far, no patients tested positive.
3. Hospital officials found visible residue on some surgical equipment.
4. The hospital's staff is now undergoing retraining.
5. The Washington State Department of Health stated the contamination probably occurred due to lack of proper cleaning and sterilization training.
