Enteroviruses\u00a0<\/em>are transient inhabitants of the gastrointestinal tract, and are stable at an acidic pH. Picornaviruses are small, ether-insensitive viruses with a RNA genome. Coxsackie viruses fall into two groups, A and B. There are 23 serotypes with Coxsackie A group and six serotypes within Coxsackie B (serotypes 1-6).<\/p>\n<p>Coxsackie A was first isolated during poliomyelitis outbreaks in 1947 from feces of paralyzed children in Coxsackie, New York.\u00a0 Coxsackie B was isolated one year later from cases of aseptic meningitis.<\/p>\n<h3>Disease\/Infection<\/h3>\n<p>Myositis, pleurodynia, encephalitis, aseptic meningitis, paralysis (infrequently), pericarditis, myocarditis, epidemic myalgia, acute respiratory infection, and conjunctivitis<\/p>\n<h3>Pathogenicity<\/h3>\n<p>Around 90% of infections caused by non-polio enteroviruses are asymptomatic or result in self-limited febrile illness. Severity of symptoms depend on age, immune status, and gender of the host.<\/p>\n<p>Coxsackievirus B (CVB) is a significant cause of viral myocarditis. Studies suggest that 70% of the general public will be exposed to cardiotropic viruses with half of these developing acute viral myocarditis.\u00a0 Peak age group for myocarditis caused by CVB is young adults, ages 20-39, and males more than females. Although a majority of subjects recover without issue from acute myocarditis, some 10-20% with symptoms can go onto develop chronic disease, that of dilated chronic cardiomyopathy.<\/p>\n<p>Group B viruses are also the dominant form causing of aseptic meningitis in adults and children. In general, all enteroviruses account for about 5% of all acute encephalitis in tested samples.<\/p>\n<ul>\n<li><strong>Special Populations at Risk<br \/>\n<\/strong>Immune deficiency, malnourished, pregnancy, and newborns<\/li>\n<\/ul>\n<h3>Biosafety Information<\/h3>\n<p><strong> Risk Group\/ABSL2<br \/>\n<\/strong>Risk Group 2<br \/>\nBiosafety level 2 Practices<\/p>\n<p><strong>Modes of Transmission<\/strong><\/p>\n<div class=\"responsive-table\"><table>\n<tbody>\n<tr>\n<td><\/td>\n<td>Transmission<\/td>\n<\/tr>\n<tr>\n<td>Skin Exposure (Needlestick, animal bite, or scratch):<\/td>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<td>Mucous Membrane Exposure Splash to Eye(s), Nose or Mouth:<\/td>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<td>Inhalation:<\/td>\n<td>Yes<\/td>\n<\/tr>\n<tr>\n<td>Ingestion:<\/td>\n<td>Yes<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<div>\n<p><strong>Host Range\/Reservoir<\/strong><br \/>\nHumans<\/p>\n<\/div>\n<div>\n<p><strong>Symptoms<\/strong><\/p>\n<p>The majority of Coxsackie infections are asymptomatic and self-limiting.\u00a0 Though Coxsackie A is typically responsible for the syndrome of Hand-Foot- and-Mouth Disease, it is Coxsackie B that is associated more with the cardiovascular complications such as myocarditis and especially in infants and the younger population, as well as aseptic meningitis\/encephalitis cases.<\/p>\n<p>An acute viral disease may be characterized by paroxysmal spasmodic pain in chest which may be intensified by movement.\u00a0 It is usually accompanied by fever and headache.
