[1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
The infection can affect any skeletal muscle, but most often infects the large muscle groups such as the quadriceps or gluteal muscles. [2] [4] [5] Pyomyositis is mainly a disease of children and was first described by Scriba in 1885. Most patients are aged 2 to 5 years, but infection may occur in any age group.
The HTLV-1 virus can cause leukemia, but in most cases lies dormant and most people end up being lifelong carriers of the virus. One review says that the best evidence points towards a connection with some type of retrovirus and that a retroviral infection combined with immune recognition of the retrovirus is enough to trigger the inflammation ...
Respiratory syncytial virus (RSV) causes infections of the breathing passages and lungs. It's so common that most children have been infected with the virus by age 2, according to the Mayo Clinic .
In other cases, the virus can cause systemic disease through a disseminated infection spread throughout the body. The predominant mode of viral dissemination occurs through the blood or lymphatic system , some of which include viruses responsible for chickenpox ( varicella zoster virus ), smallpox ( variola ), HIV ( human immunodeficiency virus ).
Echovirus types 1,6,8,9, and 19 and Coxsackie A virus types 4,6,9, and 10 are associated with Bornholm disease. The most common strains causing Bornholm disease are Coxsackie B3 and A9. Viral proliferation in the muscles of the chest wall, diaphragm, and abdomen are thought to contribute to the typical presentation that characterizes the ...
Newborns can develop herpes virus infections through contact with infected secretions in the birth canal. Other viral infections are acquired by breathing air contaminated with virus-containing droplets exhaled by an infected person. Arbovirus infections are acquired from bites by infected insects (called epidemic encephalitis). Viral central ...
Infected surfaces can be cleaned with solutions containing bleach to kill the virus. In addition, be aware that there are other foodborne illnesses, too, such as E. coli, salmonella and listeria.
