ECHO Virus Infection Diagnosis and Treatment


Diagnosis and Treatment of ECHO Virus Infection

ECHO virus infection (ECHO virus infection), infection caused by ECHO virus. After infection with this virus, humans develop symptoms of the gastrointestinal tract, nervous system, and respiratory tract. Severe cases can have heart, liver, brain and other organ lesions. Most popular in summer and autumn. 

This virus and the Coxsackie virus often co-exist and are widely distributed throughout the world. The incidence of children is much higher than that of adults. Patients and people with the virus are the source of infection. They are mainly transmitted through the intestine. They can also be transmitted through the respiratory tract in the early stages of infection. The virus can also pass to the fetus through the placenta, causing intrauterine infection.

The first strain of ECHO virus was isolated from rectal swabs of healthy children during a 1950 investigation of poliovirus. Because it was not assigned to an existing virus genus at that time, and it was not aware of its relationship with human diseases, Call it an "orphan virus". 

In 1955, it was officially named ECHO virus, which is the abbreviation of enteric cytopathic human orphan virus. Many serotypes have been discovered in the future. The ECHO virus is now an enterovirus of the picornaviridae family. The virus is highly resistant, resistant to ether and 70% ethanol and 5% coal phenol soap, but it is very sensitive to oxidants.

What is the Clinical manifestation of Enterovirus infection?

The virus can be transmitted to various organs through the blood circulation, causing a wide range of lesions. The clinical manifestations vary with the organs it invades, mainly causing the following diseases:

i.  Nervous system diseases. There are mainly aseptic meningitis, muscle relaxation paralysis, encephalitis, ataxia, Guillain-Barre syndrome (acute infectious polyradiculoneuritis). 

ii. Epidemic chest pain. It is mainly manifested by paroxysmal severe muscle pain, which is common in the chest and can affect breathing movements. Children also often complain of abdominal pain, which is easily misdiagnosed as appendicitis. Shock may even occur during severe pain. The course of disease is usually 5 to 7 days, and myalgia can recur.

iii. Rash. Prone to occur in young children, and may be accompanied by ocular conjunctivitis. 

In 1951, the epidemic of maculopapular rash in Boston, USA, named "Boston rash", manifested as rash on the first and second days of low fever, distributed on the face, chest, hips and limbs. The condition is mild. 

iv. Respiratory diseases. Some types of ECHO virus can cause mild upper respiratory tract infections, with fever, sore throat, and general malaise, and are often prevalent in young children. Sometimes it can cause lower respiratory tract infections, and lethal pneumonia in individual cases.

v. Gastrointestinal diseases. Presentation of diarrhea. 

vi. Eye disease

vii. Myocarditis

What are the Diagnosis and Treatment Enterovirus infection?

Diagnosis can be confirmed based on epidemiological data, typical clinical manifestations, virology and serology. Currently there is no specific treatment, mainly symptomatic treatment.
