Kawasaki disease incubation period
Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a common pediatric fever and rash illness, primarily a systemic small vessel vasculitis. Kawasaki disease is not contagious, so it has no incubation period; only infectious diseases have incubation periods. If it were contagious, typical manifestations would include persistent high fever, pinpoint appearances around the eyes and mouth, typical rash, swelling of the hands and feet, and non-purulent swelling of the cervical lymph nodes. Therefore, Kawasaki disease has no incubation period and is a vasculitis mediated by immune mechanisms.
Does baby eczema spread?
Babies with eczema indicate that the child has skin damage. Eczema is a common skin disease in infants and is not contagious, so eczema does not spread as only infectious diseases are contagious. When a child has eczema, the first step is to ensure proper moisturizing. On this basis, under the guidance of a doctor, some mild corticosteroids can be used. Normally, if we come into contact with a child who has eczema, we will not contract it ourselves. Parents can be reassured about this, as this is an inherent immune response of the child and is not spread through contact or the respiratory or digestive tracts.
Which department should a newborn with jaundice go to?
If a newborn has jaundice, it is first necessary to distinguish whether it is physiological jaundice or pathological jaundice. For physiological jaundice, it is self-healing, so there is no need to visit a hospital. As for pathological jaundice, it occurs within 24 hours after birth, or the daily increase in jaundice is particularly large, exceeding the normal range. In such cases, the child should be taken to the hospital for timely medical treatment. Generally, for general hospitals, it is appropriate to visit the pediatric department. If it is a children's hospital or a municipal maternal and child health hospital, then the child should be taken to the neonatology department. Neonatologists will actively treat the child's jaundice and, as a rule, pathological jaundice requires hospitalization.
Causes of Hand, Foot, and Mouth Disease
Hand, foot, and mouth disease is a rash illness characterized by scattered papules and vesicles on the hands, feet, mouth, and buttocks, caused by an enterovirus infection. It is a contagious disease caused by a viral infection, specifically by Coxsackievirus A16 and Enterovirus 71, which are part of the enterovirus group. Other Coxsackie enteroviruses can also cause hand, foot, and mouth disease. Common enterovirus infections can also lead to hand, foot, and mouth disease. This means that children who have had hand, foot, and mouth disease can potentially get it again, and this is important knowledge for everyone to understand.
What are the symptoms of a cold in children?
Pediatric colds, also known as acute upper respiratory infections, exhibit symptoms that can be categorized into local and systemic symptoms. Local symptoms include nasal congestion, sneezing, runny nose, mild coughing, discomfort in the throat, and sore throat. Systemic symptoms primarily consist of overall weakness, fever, reduced appetite, nausea, vomiting, diarrhea, abdominal pain, and generalized aches. In infants and toddlers, local symptoms are generally not as pronounced, while systemic symptoms tend to be more severe. For some children aged six months to three years, colds accompanied by fever can also lead to febrile convulsions. In older children, local symptoms are usually more prominent, while systemic symptoms are milder. Regarding this type of acute upper respiratory infection, there are two common specific types in children: herpangina and pharyngoconjunctival fever.
How to treat baby eczema?
Infant eczema, also known as atopic dermatitis, is mainly caused by an allergy to milk protein, so it is important to pay attention to the child's diet. Nursing mothers should avoid consuming beef, lamb, nuts, and seafood. Additionally, for children who are formula-fed, depending on the severity of the eczema, choose either amino acid formula or hydrolyzed protein formula. The treatment of eczema primarily involves moisturizing the skin. Therefore, applying a thick layer of moisturizer specifically designed for babies on the affected areas can be very effective in treatment. Furthermore, on top of moisturizing, under the guidance of a doctor in a hospital, a weak steroid cream can be used. With the above management, eczema can generally be controlled quickly.
What medicine should a child take for vomiting and diarrhea?
In cases where children experience vomiting and diarrhea, it is generally considered that the child may have acute gastroenteritis. For particularly severe diarrhea, where the stool is watery, it is advisable to give the child montmorillonite powder to protect the intestinal mucosa, along with probiotics, and oral rehydration salts to prevent dehydration. Because severe vomiting can also be a concern, treatments to stop vomiting can be implemented, such as administering Vitamin B6 via injection, or by administering oral aluminum phosphate gel. With the above treatments, vomiting and diarrhea can generally be well controlled. If the child has already developed moderate or more severe dehydration due to the vomiting and diarrhea, accompanied by varying degrees of electrolyte disorder, hospitalization for intravenous fluid therapy is then necessary. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
Is hand, foot, and mouth disease dangerous?
Hand, foot, and mouth disease is a common pediatric disease caused by an intestinal viral infection, characterized by fever and rash, with severities ranging from mild to severe. If caused by a typical enterovirus infection, hand, foot, and mouth disease generally recovers quickly with antiviral treatment and proper care of the mouth and skin. However, if caused by an EV71 virus infection, it poses certain risks. This is because the EV71 virus can affect the central nervous system, leading to symptoms such as increased intracranial pressure and respiratory and circulatory dysfunction. These complications can result in respiratory failure and cardiac failure, which are severe manifestations. Therefore, hand, foot, and mouth disease caused by the EV71 virus carries certain risks. Thus, it is important to administer a vaccine made from the EV71 virus to children to prevent severe hand, foot, and mouth disease.
Can Tetralogy of Fallot be cured?
Tetralogy of Fallot is a type of congenital heart disease linked to family genetics and is considered quite severe among congenital heart conditions. Generally, within a few months after birth, children will exhibit cyanosis of the skin. It is crucial to perform surgery on the child promptly in such cases. Currently, the level of pediatric cardiothoracic surgery in our country has developed very rapidly. For typical cases of Tetralogy of Fallot, surgical treatment can be curative. Moreover, there are no specific requirements regarding weight and age for children undergoing heart surgery nowadays. Therefore, once Tetralogy of Fallot is diagnosed in young children, it is best to perform surgery as soon as possible. These children can then grow up, develop normally, and attend school like their peers.
Do infants with sudden rash need to take medicine?
Childhood rash illness is a common pediatric acute fever caused by herpes simplex virus types 6 and 7, characterized by a high fever lasting three to four days, followed by the appearance of a rash after the fever subsides. The treatment mainly involves symptomatic management. When a child's body temperature exceeds 38.5°C, antipyretic medications such as acetaminophen and ibuprofen suspension can be administered. It is also important to ensure the child stays well-hydrated. Before the rash appears, it is not certain that it will occur. For most children who have been confirmed through a blood test to have a viral infection, antiviral medications might sometimes be administered. However, these medications ultimately do not shorten the duration of the illness. Once the child has been feverish for three days and the rash appears, no further medication is typically necessary; just ensure the child drinks plenty of fluids. The rash usually spreads within about two days and then quickly fades. (Please administer medication under the guidance of a professional physician.)
