The following are the main clinical cases of otitis media. 1. Patients with purulent otitis media have a large number of bacterial infections in the ear canal, and when they share the ear-extracting spoon with other patients, the bacteria can be transmitted to other patients through the spoon and induce otitis media and other related diseases. 2. Patients with fungal otitis externa and fungal otitis media share the ear-extracting spoon with other patients, and these fungi can be transmitted to other patients through the spoon and induce fungal otitis externa and other related diseases. 3. 3. Patients with otitis media may also have diseases related to hepatitis B, syphilis, AIDS, etc. Under normal circumstances, sharing an ear-removing spoon with other patients will not normally transmit the disease. In some cases, if the ear canal is damaged or bleeding, the possibility of infection cannot be ruled out.
