Coxsackievirus B

Can coxsackievirus B trigger immunity illness ?

A common RNA virus, Coxsackie hails from the Picornaviridae family and genus enterovirus. The virus is categorized into two types: A and B grouped viruses. Coxsackie viruses are amongst the leading factors causing aseptic meningitis.

What is Coxsackievirus B?

The B grouped coxsackievirus is involved in the majority of the nervous system and heart muscle toxicities in both children, and adults. The immune-compromised groups are also at an increased risk of catching the infection. These viruses are a common source of myocarditis, which is inflammation of heart’s muscular walls, and dilated cardiomyopathy (a category of disorder where the heart muscle is weakened, resulting in irregular pumping and dilation of cardiac chambers).

How common is the medical condition?

Just like norovirus, the coxsackievirus is characterized as one of the most common viral infections. Coxsackie viruses are found across the globe, mostly in the summer season with sporadic cases observable all year round.

Symptoms of Coxsackievirus B

Human Coxsackievirus B infections are asymptomatic (without symptoms), however, some underlying indications are as follows:

  • Epidemic pleurodynia, and inflammation in the chest
  • Initial phase forms blisters, rashes causing itchiness, usually on feet, buttocks, and genitals
  • Headache, febrile feeling with a slight stiffness in the neck
  • May cause viral meningitis, also known as aseptic meningitis
  • Might lead to epilepsy or change of personality in infants

 Other significant Coxsackievirus infections

Coxsackievirus infections are responsible for triggering many other conditions, and they can be associated with the following types:

  • Congenital infections: It is a common virus, and may be linked to heart problems in fetuses
  • Gastrointestinal disease: The virus can be a cause for hepatitis, non-bacterial diarrhea or other gastrointestinal related diseases
  • Myositis: Can lead to Inflammation in a muscles or tendons
  • Purpuric rashes: Coxsackievirus can also be a factor behind sporadic rashes or blemishes.

Fever for 2-3 days can also pervade when you suffer from Coxsackievirus. Though, a majority of people show no signs at all.

How is the condition diagnosed?

Medical examination and patient’s history is thoroughly studied, to track the signs of the infection. Some tests may also include sampling feces and fluids from the back of the throat.

How to prevent the infection?

Prevention is challenging but the virus can be controlled through proper sanitation.  Avoiding direct contact with HFMD patients is advised. The CDC states, "you might get infected by kissing someone who has hand, foot, and mouth disease or by touching a doorknob that has viruses on it, then touching your eyes, mouth, or nose." General cleanliness, regular hand washing and avoiding contaminated surfaces are some of the best preventive measures.

 Treatment options for Coxsackievirus B

A patient can seek supportive medical care. Antibiotics can provide relief but a complete medical therapy is required. Over-the-counter treatments can also reduce discomfort. Fluid intake is also suggested to prevent excessive dehydration.

The rare infections require doctors discretion for the course of treatment which will be best suited for the patient.

The prognosis for Coxsackievirus B is highly preferred. Awareness regarding hygiene, and avoiding transmission needs to be generated amongst the general public.
