Even if the object is reused after it has dried, the risk of HIV infection is said to be near zero, but still, safety first. If there are specific concerns about possible infection or symptoms such as fever, fatigue, or swollen lymph nodes, it is recommended to see a healthcare provider for accurate testing and consultation.
