In the cytoplasm, the satellite virus hijacks the morphogenesis machinery of its helper virus to produce its progeny. Virophages are small, double-stranded DNA viral phages that require the co-infection of another virus. The co-infecting viruses are typically giant viruses. Virophages rely on the viral replication factory of the co-infecting ...
Tonsillitis is swelling of the tonsils by a bacterial or viral infection. This inflammation can lead to airway obstruction. From tonsillitis can come a peritonsillar abscess which is the most common upper airway infection and occurs primarily in young adults. It causes swelling in one of the tonsils, pushing the uvula to the unaffected side. [9]
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. [ 3 ] [ 4 ] This commonly includes nasal obstruction, sore throat, tonsillitis , pharyngitis , laryngitis , sinusitis , otitis media , and the common cold .
This is a shortened version of the eighth chapter of the ICD-9: Diseases of the Respiratory System. It covers ICD codes 460 to 519. The full chapter can be found on pages 283 to 300 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
One of the most common causes is Staphylococcus aureus and often follows a recent viral upper respiratory infection. Bacterial tracheitis is a rare complication of influenza infection. [ 4 ] It is the most serious in young children, possibly because of the relatively small size of the trachea that gets easily blocked by swelling.
Asthmatic subjects in 9 to 11 years old, 80% to 85% of asthma exacerbations that were associated with reduced peak expiratory flow rates and wheezing were due to viral upper respiratory tract infections (URIs). High rates of asthma attacks due to rhinovirus infection are also found in adults. [16]
Most often it is caused by viral infection and hence antibiotic therapy is not indicated in immunocompetent individuals. [10] [7] Viral bronchitis can sometimes be treated using antiviral medications depending on the virus causing the infection, and medications such as anti-inflammatory drugs and expectorants can help mitigate the symptoms.
