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 ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
It covers ICD codes 001 to 139. The full chapter can be found on pages 49 to 99 of Volume 1, which contains all (sub)categories of the ICD-9. ... 079 Viral infection ...
Pharyngitis is a type of upper respiratory tract infection. [7] Most cases are caused by a viral infection. [2] Strep throat, a bacterial infection, is the cause in about 25% of children and 10% of adults. [2] Uncommon causes include other bacteria such as gonococcus, fungi, irritants such as smoke, allergies, and gastroesophageal reflux disease.
The latter two may merely reflect viral shedding, although diarrhea has been described in animal bocaviral infections, and some patients with HBoV seem to have diarrhea independent of respiratory symptoms. [28] [29] A study in Jordan found that 9% of 220 children hospitalized with lower respiratory tract infection were infected with bocavirus. [30]
Herpes esophagitis is a viral infection of the esophagus caused by Herpes simplex virus (HSV). While the disease most often occurs in immunocompromised patients, including post- chemotherapy , immunosuppression with organ transplants [ 1 ] and in AIDS , [ 2 ] herpes esophagitis can also occur in immunocompetent individuals.
Hand, foot, and mouth disease (HFMD) is a common infection caused by a group of enteroviruses. [10] It typically begins with a fever and feeling generally unwell. [10] This is followed a day or two later by flat discolored spots or bumps that may blister, on the hands, feet and mouth and occasionally buttocks and groin.
A viral infection does not always cause disease. A viral infection simply involves viral replication in the host, but disease is the damage caused by viral multiplication. [5] An individual who has a viral infection but does not display disease symptoms is known as a carrier. [17] Mechanisms by which viruses cause damage and disease to host cells
