Viral myocarditis Viral myocarditis is a common pediatric condition with some significant symptoms and some not. If not detected and treated early, it can lead to chronic myocarditis, heart disease or multiple recurrences and even sudden death. Therefore, it is important to strengthen the health education of the parents of the children to control the recurrence of viral myocarditis and improve the cure rate. The cause of myocarditis is coxsackievirus, echovirus, poliovirus, adenovirus, hepatitis B virus, influenza parainfluenza virus, hepatitis B virus, herpes simplex virus, and mumps virus, among which coxsackievirus is the most common. Clinical manifestations Viral myocarditis usually occurs with a history of antecedent infection. Symptoms of myocarditis may appear during the symptomatic phase of the primary illness or during the recovery phase. If present during the symptomatic phase of the primary disease, the presentation may be masked by the primary disease. Most children have fever, generalized aches and pains, sore throat, and diarrhea before the onset of the disease. This reflects a systemic viral infection, but some children have mild and insignificant symptoms of the primary illness, which must be noticed only after careful questioning, whereas the symptoms of myocarditis are more pronounced, with sudden onset of malaise, cyanosis, shortness of breath, chills in the extremities, excessive sweating, pallor, unexplained crying, abdominal pain, complaints of precordial discomfort, and chest tightness during the course of a cold or 1-3 weeks after cure. Fainting or heart failure or cardiogenic shock may occur in a few of these seriously ill children, and even sudden death may occur. Parents should actively cooperate with the doctor for treatment. Generally viral myocarditis is treated in the hospital for about 3 weeks and then can be treated at home. Due to the special nature of the virus damage to the heart, the recovery period is longer than the virus damage to other organs, usually 3 months to 6 months. Some children with the disease still insist on going to school during this period because they do not want to delay their classes, but they should be careful not to overexert themselves, limit their physical activities appropriately, and visit the hospital regularly to review and dynamically monitor changes in their condition. Care of diet Supplementation of multivitamin and nutrient-rich diet. (1) Eat less and more meals, can be 1-2 taels/meal, 6-8 meals/day to prevent overfilling and increase the burden on the heart. (2) Eat high-quality protein, such as fish, eggs, meat, milk, pig liver, etc., rich in vitamins and easy to digest food, avoid spicy and stimulating food. (3) Pay attention to the color, aroma and taste of food to suit the child’s appetite and to promote appetite, and encourage the child to eat and pay attention to dietary hygiene. (4) Encourage the child to drink more water, eat more vegetables and fruits, and drink honey water to keep the bowels open and prevent constipation. When constipation is present, do not force the bowel movement, and if necessary, give corkage. When the condition allows, move around and have regular bowel movements. The treatment of myocarditis is a long process, parents and children should actively cooperate with the treatment and care. (1) Go home and actively prevent upper respiratory tract infections and gastrointestinal infections, avoid going to public places as much as possible during the epidemic period of the disease, increase and decrease clothes in time when the weather changes to prevent colds, strengthen nutrition and pay attention to dietary hygiene.
