What is echovirus infection?
Echoviruses are common human pathogens that cause a range of illnesses, from minor febrile illness to severe, potentially fatal conditions (eg, aseptic meningitis, encephalitis, paralysis, myocarditis). Individual serotypes have different temporal patterns of circulation and cause different clinical manifestations.
What type of virus is echovirus?
Echovirus is one of several families of viruses that affect the gastrointestinal tract. Together, these are called enteroviruses. These infections are common. In the United States, they are most common in the summer and fall.
Can echovirus cause meningitis?
A much less common symptom of an echovirus infection is viral meningitis. This is an infection of the membranes surrounding your brain and spinal cord. Viral meningitis can cause the following symptoms: fever.
What diseases are caused by arbovirus?
Examples include California encephalitis, Chikungunya, dengue, Eastern equine encephalitis, Powassan, St. Louis encephalitis, West Nile, Yellow Fever, and Zika.
Where does echovirus replicate?
Some viral replication of an echovirus occurs in the nasopharynx after infection and then spreads to regional lymph nodes. However, most viral particles are swallowed and they reach the lower gut tract, where the virus is presumed to bind to specific receptors.
Is Norwalk the same as norovirus?
Noroviruses are members of a group of viruses called caliciviruses also known previously as “Norwalk-like viruses.” Norovirus facts, including common symptoms and how the disease is spread.
Is arbovirus contagious?
Most arboviruses aren’t transmitted from person to person, usually making humans dead-end hosts. A few exceptions are dengue fever and yellow fever, which can be transmitted from person to person through insect bites.
How many different types of Echoviruses are there?
Echoviruses were originally classified into 34 serotypes. Echovirus 10 has been reclassified as reovirus 1 and echovirus 28 as rhinovirus 1. Echovirus 9 is now recognized as the same as coxsackievirus A23.
What is the scientific name of echovirus?
Echovirus refers to various viruses primarily in the family Picornaviridae. Echovirus takes its name from ” e nteric c ytopathic h uman o rphan virus “. Echoviruses were originally not associated with disease but many have since been identified as disease-causing agents. The term “echovirus” was used in the scientific names of numerous species.
Which serotypes of echoviruses cause respiratory disease?
Among the echoviruses, serotype 11 is the most firmly established cause of respiratory disease, although serotypes 4, 8, 9, 20, 22, and 25 may also be causal agents. In volunteers infected experimentally and, occasionally, in patients with naturally acquired disease, some coxsackieviruses and echoviruses may be linked with pneumonia.
Is echovirus A23 the same as coxsackievirus?
Echovirus 9 is now recognized as the same as coxsackievirus A23. Echovirus 22 and 23 have been reclassified as members of the Parechovirus genus, and echovirus 34 is a variant of coxsackievirus A24 7). Echoviruses were first isolated from the feces of asymptomatic children in the context of epidemiological studies of polioviruses.
