According to our experience during the last years viral upper respiratory tract infection usually precedes or coincides with acute otitis media (AOE). Epidemiological and clinical aspects of AOE in three different regions in Bulgaria appear to be very similar.
Epidemiological clinical research have shown a strong relationship between viral upper respiratory tract infection and acute otitis media. According to a study of Grievs at al viral replication was seen from the site of inoculation to the pharyngeal orifice of the eustachian tube by 48 hours, and the virus could be detected in the distal part of the eustachian tube after 5 days.
We have examined 945 children between 1,5 and 12 years old. The most frequently found viruses were: RSV, adenovirus, coronavirus, influenza virus. In only 15% of the cases more then two viruses ware isolated.In our research, a respiratory virus was detected in 31% of 945 children with AOE. Most of the children with viral infections have attended children gardens and schools more than 6 months.
In 58% of cases different kinds of bacteria were isolated. We found difficulties to prove which is the main causing agents of the infections-virus ore bacteria.
