Rash "four unlike": unlike mosquito bites, unlike drug rash, unlike lip and gum herpes, unlike chickenpox.
Hand, foot and mouth disease mainly occurs in children under 4 years old, but adults may also get sick. It can be said that everyone is susceptible. After infection, only the immunity of this type of virus is obtained, and there is no cross immunity to other types of viruses, that is, hand, foot and mouth disease may occur again after infection with other types of viruses.
(3) After oral herpes is broken, there will be ulcers, frequent drooling and inability to eat.
Clinically, it does not itch, hurt, scab or leave scars.
The child's urine is yellow.
Children with severe rash may be accompanied by fever, runny nose, cough and other symptoms.
(4) Hand-foot-mouth disease is an enterovirus disease, the incubation period is usually 3-7 days, and there is no obvious precursor symptoms: most patients have sudden onset. It mainly invades hands, feet, mouth and buttocks. Because of the pain of oral ulcer, the child salivates and refuses to eat. Oral mucosal rashes appeared earlier, initially miliary maculopapules or blisters, with redness around them, mainly on the tongue and cheeks, and often on the labial and dentate sides. Spotted papules or herpes appear on the distal parts such as hands and feet, flat or convex, and the rash is not itchy. The maculopapular rash turns from red to dark in about 5 days, and then disappears. Herpes is a round or oval flat protuberance with turbid liquid in it, and its long diameter is consistent with the direction of dermatoglyphics. For example, soybeans vary in size, which are generally painless and leave no trace after healing. Hand, foot and mouth disease may not all happen to the same patient. Blisters and rashes usually subside within a week. ?
(5), hand, foot and mouth disease can generally be cured within a week, but if herpes attacks before, it is very easy to get infected. Hand, foot and mouth disease has the characteristics of high epidemic intensity, strong infectivity and complicated transmission route. The virus can be transmitted to healthy children through saliva drops or food bitten by flies with the virus, through the nose and mouth or direct contact.
(6) Complications
Hand, foot and mouth disease is manifested in the skin and mouth, but the virus can invade important organs such as heart, brain and kidney. When the disease is prevalent, the clinical monitoring of patients should be strengthened. If there is high fever and unexplained leukocytosis, we should be alert to the occurrence of fulminant myocarditis. In recent years, it has been found that EV7 1 is more susceptible to aseptic meningitis than CoxAl6, and its symptoms are fever, headache, stiff neck, vomiting, irritability and restless sleep. Occasionally, nonspecific red papules and even punctate bleeding spots can be found in the body. People with central nervous system symptoms are more common in children under 2 years old.
