Dr. Jin Zhongkui
The "Big Three Positive" (major three positives) is mainly transmitted through blood transfusions, mother-to-child transmission, and sexual contact. It can also be spread through direct or indirect contact with contaminated objects. Once diagnosed with the "Big Three Positive," strict isolation from family members is necessary. Sharing utensils or personal items should be avoided to prevent transmission to family members, and sexual activity must be completely avoided.
