Core Viewpoint - A 4-year-old girl was diagnosed with congenital syphilis after being infected by her grandmother, who had untreated syphilis and fed her using her mouth, leading to indirect transmission through saliva [1][2]. Group 1: Transmission Methods - Syphilis can be transmitted through various means beyond sexual contact, including mother-to-child transmission during pregnancy or childbirth [3]. - Blood transmission can occur through contaminated blood transfusions or shared medical equipment [4]. - Indirect contact transmission can happen through shared utensils, mouth-to-mouth feeding, or kissing, especially if both parties have oral mucosal injuries [4].

Group 3: Other Diseases Transmitted via Saliva - Helicobacter pylori, influenza viruses, herpes viruses, and bacteria causing cavities can also be transmitted through saliva [7][8]. - Close contact behaviors, such as kissing and sharing food, increase the risk of transmission for these pathogens [8].
