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 A virus is a subgroup of enterovirus A, which are small, non-enveloped, positive-sense, single-stranded RNA viruses. Its protective, icosahedral capsid has an external portion that contains sixty copies of viral proteins (VP1,-2,-3) and an internal portion surrounding the RNA genome containing sixty copies of VP4 viral proteins.
Symptoms of infection with viruses in the Coxsackie B grouping include fever, headache, sore throat, gastrointestinal distress, extreme fatigue as well as chest and muscle pain. It can also lead to spasms in arms and legs. This presentation is known as pleurodynia or Bornholm disease in many areas. Patients with chest pain should see a doctor ...
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.
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.

Public health experts are warning of a ‘quad-demic’ this winter. Here’s where flu, COVID, RSV, and norovirus are spreading
Common symptoms can include myocarditis, meningoencephalitis, and hepatitis. Other less severe symptoms can include pneumonia, Gastrointestinal symptoms, pancreatitis, and seizures. Patients with Coxsackie B4 virus have seemed to have herpangina, tonsillitis, and pharyngitis. [6] CB4 virus has caused transplacental infections in mice.
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
