Middle Ear Infection which is medically denote to as intense otitis media is an exceedingly common condition date in children . In fact , it is forecast that about 85 % of children under the age of 3 get move by middle ear infection . While these infections tend to have a bacterial cause , latest studies have shown that these contagion can also be triggered by viral infection in the nose . The most vernacular virus that can taint both the nose and the ear is the flu virus.[1,2,3 ]
The study states that the grippe virus inflames the nasal tissue paper and increase the number of bacteria and their leaning to travel through the eustachian tube and cause an transmission in the middle ear . This study is put out and available in the American Society of Microbiology.[1,2,3]This article gives further information on how viral infection in the olfactory organ activate bacterial infection in the capitulum .
How Can Viral Infection In Nose Trigger Bacterial Infection In Ear?
The study was conducted by a radical of researchers from the Wake Forest Baptist Medical Center in Winston - Salem , NC . The findings as stated are uncommitted in American Society of Microbiology in the journal Infection and Immunity . The lead research worker of this study states that bacteria are course present in the body particularly in the stomach and pharynx , but they are also present in the olfactory organ . These bacterium generally do not induce any problem . However , in some illustration these bacteria can trip to the pinna and stimulate in-between ear infection.[1,2,3 ]
The investigator conducted an animate being study . The study designate that when the olfactory organ was infected with a grippe virus and bacteria that do ear infections , it resulted in inflammation of the nasal tissue . As a result of this excitation , the number of bacterium increased and with it also increased the likelihood of them traveling through the eustachian pipe into the middle ear result in an infection . The bacterium that was investigated in the study was Streptococcus pneumoniae . This bacteria is known to be by nature present in the nozzle of children in the dormant and active phases.[1,2,3 ]
In the torpid phase , the bacteria is completely harmless but in the active stage it tend to have infection , especially in the ears . The study further suggest that the presence of flu virus resulted in infection by this bacteria even in its sleeping stage . The researchers establish out that the bearing of the influenza computer virus accelerated the growth of S. pneumoniae and infect the middle ear.[1,2,3 ]
Researchers believe that the reason behind it is that the viral infection in the nose provoke an resistant response to this bacterium resulting in the bacterium infect the ears even in its dormant or benign land . Middle ear transmission is quite a uncouth occurrent in United States which is quite heavy on the pocket.[1,2,3 ]
The American Academy of Otolaryngology states that 3 in 5 children develop their first middle ear transmission by the metre they turn over one yr of age . This figure increase to 4 out of 5 child by the prison term they are 3 and almost every child has had it at least once by age 5 . It is calculate that approximately 25 million infirmary visits every year for children are due to center ear infections . The bacterium mainly responsible for these infections is the Streptococcus pneumoniae.[3 ]
In closing , viral infection in the nose is indeed responsible for for middle pinna bacterial infection . This has been proven in a study conducted on animal models . The main virus responsible for it is the flu virus . It speed the increment of the naturally present streptococcus pneumoniae bacteria in the nose and also increases their propensity to travel through the eustachian thermionic tube in the mediate capitulum and induce infection.[1,2,3 ]
This was seen in both the states that the bacteria has namely , benignant and active states . Why does this happen was explained in that the flu computer virus evokes an immune response to the bacteria which accelerates its emergence and induce middle ear infections . It is estimated that close to 25 million infirmary visits every yr in the United States for children are due to mediate ear infections.[1,2,3 ]
