Herpangina, also called mouth blisters, is a painful mouth infection caused by coxsackieviruses.Usually, herpangina is produced by one particular strain of coxsackie virus A (and the term "herpangina virus" refers to coxsackievirus A), [1] but it can also be caused by coxsackievirus B or echoviruses. [2]
Coxsackieviruses are divided into group A and group B viruses based on early observations of their pathogenicity in neonatal mice. [1] Group A coxsackieviruses were noted to cause a flaccid paralysis (which was caused by generalized myositis) while group B coxsackieviruses were noted to cause a spastic paralysis (due to focal muscle injury and degeneration of neuronal tissue).
Coxsackie B virus infection may also induce aseptic meningitis. As a group, they are the most common cause of unexpected sudden death , and may account for up to 50% of such cases. [ 6 ] The incubation period for the Coxsackie B viruses ranges from 2 to 6 days, and illness may last for up to 6 months in extreme cases, but may resolve as quickly ...
Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
Thankfully, the infection can usually be managed with home treatments, like warm compresses, and goes away on its own within a few weeks. Hand, foot and mouth disease Hand Foot and Mouth virus ...
Coxsackie B4 virus and type 1 diabetes [ edit ] One theory proposes that type 1 diabetes is a virus-triggered autoimmune response in which the immune system attacks virus-infected cells along with the beta cells in the pancreas , [ 8 ] [ 9 ] but to date there is no stringent evidence to support this hypothesis in humans.
Cases of norovirus, a.k.a. the stomach bug, are surging in the U.S. right now. There is no specific medication to treat norovirus. Doctors share tips for feeling better, sooner. The U.S. is seeing ...
The amount of virally infected cardiomyocytes varies in different stages of the disease. In a mouse model, at the acute stage (7 days after infection with coxsackievirus B3) approximately 10% of the myocytes are infected and could affect overall cardiac function. In chronic murine infection, the percentage of infected cardiomyocytes are much lower.
