Coxsackie and Echovirus Infections
Introduction
Introduction to Coxsackie and Echovirus infection Coxsackie virus and Echovirus invade through the mouth, and then into the blood, distributed in a variety of organs cause a variety of different clinical manifestations. The same virus can cause different clinical manifestations, and the same clinical manifestation can be caused by different viruses. The disease spreads all over the world and is distributed frequently. The incidence rate is high in summer and autumn. The source of infection is patients, recessive infections and carriers, and the proportion of dominant and latent infections is 1:50-100. Contact with oral infections in daily life is the main route of transmission. It can also be transmitted from the mother to the fetus through drinking water, food and respiratory tract and through the placenta. basic knowledge The proportion of illness: 0.012% Susceptible people: no specific population Mode of transmission: mother-to-child transmission of respiratory tract, fecal-oral transmission Complications: myocarditis, epilepsy, meningitis, pneumonia, viral gastroenteritis
Cause
Coxsackie virus and Echovirus infection cause
Coxsackie virus can be transmitted through the respiratory tract and digestive tract. Pregnant women can be transmitted to the fetus through the placenta after infection, which can cause fetal malformation or even stillbirth. Coxsackie virus can be divided into two types, A and B. The effects and symptoms are different.
Prevention
Coxsackie virus and Echo virus infection prevention
Do a good job in manure management, do a good job in the environment and food hygiene, and develop good personal hygiene habits.
Complication
Coxsackie virus and Echovirus infection complications Complications Myocarditis Epilepsy Meningitis Pneumovirus Gastroenteritis
Coxsackievirus type A infection has little effect on neonates, mainly manifested as gastroenteritis. Coxsackievirus type B infection can be mild or severe after neonatal infection, lighter is only mild fever, and severe can occur. Myocarditis, meningoencephalitis, epilepsy, etc., the symptoms of Echovirus infection may vary greatly depending on the degree of infection. Lighter cases may have no obvious symptoms. In severe cases, meningitis, myocarditis, pneumonia, and even death due to liver necrosis may occur. .
Symptom
Coxsackie virus and Echovirus infection symptoms Common symptoms Herpes simplex herpes meningitis rib pain
Symptoms caused by coxsackievirus type A are:
(1) Symptoms of upper respiratory tract infection: fever, sneezing, salivation, coughing, etc.
(2) herpetic angina: small herpes occurs in the pharynx, tongue, soft palate, etc., may be accompanied by tonsil enlargement.
(3) rash: mainly distributed in the face, fingers, toes, etc., for herpes and maculopapular rash.
In addition, there may be meningoencephalitis and viral myocarditis.
The symptoms of Coxsackie virus type B infection are: characteristic infectious thoracic rib pain, accompanied by fever, myocarditis, and encephalitis.
The symptoms of Echovirus infection can be seen: upper respiratory tract infection, maculopapular or measles-like rash, fever, aseptic meningitis, etc.
Examine
Coxsackie virus and Echovirus infection check
1. The patient's body fluid (cerebrospinal fluid, herpes fluid, pericardial fluid, pleural effusion, etc.) can be diagnosed by separating the virus.
2. The antibody appeared in the serum during the recovery period, or the serum antibody titer increased by more than 4 times.
Diagnosis
Diagnosis and identification of Coxsackie virus and Echovirus infection
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
Coxsackievirus and Echovirus infections need to be differentiated from other viruses such as Epstein-Barr virus and adenovirus infection. The clinical manifestations of the latter two viral infections are different from those of Coxsackie virus and Echovirus infection. For example, EBV infection can cause infectious mononucleosis, which is more common in children and may be accompanied by myocardial damage. Should pay attention to identification. Each clinical syndrome should be diagnosed with the corresponding disease, mainly based on medical history, epidemiological data, clinical manifestations and laboratory tests, and mainly based on the basis of laboratory tests.
