Acute suppurative otitis media

Bacteria enter the suffocation and cause a purulent infection, called acute otitis media, which is mostly secondary to upper respiratory tract infection. Some cases may start with a viral infection, and then the bacteria invade. The most common are hemolytic streptococci, staphylococcus aureus, type III pneumococcus, and proteus. It is more common in winter and spring, and it is easy to induce in patients with hematological disease, malnutrition, allergies, and heart and lung disease, nephritis and diabetes. According to statistics, the incidence of school-age children between 5 and 16 years old is as high as 3%, and those under 5 years old are as high as 5% -10%. The incidence of Eskimos and American Indians is much higher than that of whites. Whether this is due to racial genes or living conditions has not been determined.
