Enterovirus 71 can cause Hand, Foot and Mouth Disease

Doc, What is Enterovirus 71 and does it cause Hand, Foot and Mouth Disease?

Enterovirus 71 (EV-71), is a virus which causes hand, foot and mouth disease (HFMD). The EV-71 has been known to generally cause severe complications among some patients infected with (HFMD)

Hand-foot-and-mouth disease ,also known as Herpangina, is an acute viral illness that presents as a vesicular eruption in the mouth. HFMD can also involve the hands, feet, buttocks, and/or genitalia. Coxsackievirus A type 16 (CV A16) is the etiologic agent involved in most cases of HFMD, but the illness is also associated with coxsackievirus A5, A7, A9, A10, B2, and B5 strains. Enterovirus 71 (EV-71) has also caused outbreaks of HFMD with associated neurologic involvement in the western Pacific region, which includes Southeast Asia and recently Cambodia.

The human enteroviruses are existing viruses that are transmitted from person to person via direct contact with virus shed from the gastrointestinal or upper respiratory tract. The enteroviruses belong to the Picornaviridae family of viruses and are traditionally divided into 5 subgenera based on differences in host range and pathogenic potential.[1] Each subgenus contains a number of unique serotypes, which are distinguished based on neutralization by specific antisera. The subgenera include polioviruses, coxsackievirus (groups A and B), and echoviruses.

Symptoms include vesicles in the mouth, hands, feet and bottoms sometimes appearing as blisters. Signs involves football shaped vesicles n the buccal, toungue and posterior pharynx.

There is no specific treatment for HFMD,in fact no anti viral therapy is recomended except for supportive therapy. Paracetamol may be given for pain and fever while Antihistamines (Cetirizine, Diphenhydramine) maybe given for pruritus. It should be noted however that patients with CNS manifestations (eg, encephalitis, aseptic meningitis) may require hospitalization.

Hand ,Foot and Mouth Disease

Hand-foot-and-mouth disease (HFMD) is a viral illness with a distinct clinical presentation of oral and characteristic distal extremity lesions. Most commonly, the etiologic agents are coxsackieviruses, members of the Picornaviridae family.
HFMD is a common viral illness of infants and children. The disease causes fever and blister-like eruptions in the mouth and/or a skin rash. HFMD is often confused with foot-and-mouth (also called hoof-and-mouth) disease, a disease of cattle, sheep, and swine; however, the two diseases are not related—they are caused by different viruses. Humans do not get the animal disease, and animals do not get the human disease.
Hand-foot-and-mouth disease (HFMD) is more severe in infants and children than adults, but generally, the disease has a mild course. Symptoms such as malaise, low-grade fever, and anorexia are often present. Occasionally, patients have high fever, marked malaise, diarrhea, and arthralgias.

Infection is spread from person to person by direct contact with infectious virus. Infectious virus is found in the nose and throat secretions, saliva, blister fluid, and stool of infected persons. The virus is most often spread by persons with unwashed, virus-contaminated hands and by contact with virus-contaminated surfaces. The viruses that cause HFMD can remain in the body for weeks after a patient's symptoms have gone away. This means that the infected person can still pass the infection to other people even though he/she appears well. Also, some persons who are infected and excreting the virus, including most adults, may have no symptoms.

Usually, no medical care is necessary for hand-foot-and-mouth disease (HFMD).The topical application of anesthetics is beneficial. Viscous lidocaine, dyclonine solution, or diphenhydramine (Benadryl) may be used to treat painful oral ulcers. Antipyretics may be used to manage fever, and analgesics may be used to treat arthralgias.
