What is the order in which hand, foot and mouth rash disappears?

Hand, foot and mouth rash is a common children's skin disease in daily life. It is generally caused by infection or bacterial transmission. Children with hand, foot and mouth rash are very harmful to their health and need to be treated in time. The order in which the hand, foot and mouth rash disappears is that the skin gradually loses its redness, the fever slowly subsides, and the body returns to normal health.

What is the order in which hand, foot and mouth rash disappears?

1. Most children develop the disease suddenly, first showing symptoms of high fever, with body temperature mostly above 38 degrees, accompanied by symptoms such as headache, cough, runny nose, etc. The temperature persists. The higher the temperature, the longer the course of the disease, and the more serious the condition.

2. Herpes can be seen in the oral mucosa and lips of children at the same time as the fever or 1-2 days after the fever. After the herpes breaks, ulcers will form, which are very painful. Children often show discomfort such as irritability, crying, drooling, and not eating.

3. 1-2 days after oral herpes, maculopapular rashes can be seen on the palms, soles and buttocks of the child, most commonly on the soles of the feet. The herpes are round or oval, flat, as small as a grain of rice or as large as a pea, hard and containing turbid fluid, and surrounded by a red halo.

4. The rash of hand, foot and mouth disease in children rarely appears on the trunk and face, and generally disappears in about 7 days without causing scars or leaving marks.

5. Hand, foot and mouth disease in children is a mild, self-healing disease. The vast majority of children have a good prognosis. A small number of severely ill children may develop myocarditis and encephalitis, but the possibility is very small.

6. The entire course of the disease ends in about 1 week, and generally there are no serious consequences. As long as proper care is taken, no pigmentation marks or scars will be left on the skin.

How many days does hand, foot and mouth disease rash appear

Hand, foot and mouth disease is a common infectious disease caused by a variety of human enteroviruses, mainly affecting infants and young children. Most children have mild symptoms, with fever and rash or herpes on the hands, feet, mouth and other parts of the body as the main features. A small number of children may develop damage to the central nervous system and respiratory system, leading to aseptic meningitis, encephalitis, acute flaccid paralysis, neurogenic pulmonary edema and myocarditis. Some seriously ill children may progress rapidly and are prone to death.

Most children and adults infected will not develop symptoms, but can spread the virus. The enteroviruses that cause hand, foot and mouth disease include enterovirus 71, group A coxsackievirus, and certain serotypes of echovirus.

In the early stages of hand, foot and mouth disease, children will first have symptoms similar to upper respiratory tract infection, such as fever, cough, runny nose and drooling. Some children may have symptoms such as nausea and vomiting, and later oval or spindle-shaped blisters will appear on the backs of the fingers and toes of the hands and feet. The blisters are surrounded by red halos and the fluid in the blisters is clear. The long axis of the blisters is consistent with the skin texture.

Then the center of the blister becomes sunken, yellowed, dry, and peels off (desquamation). In addition, there are scattered, relatively hard, light red papules or blisters on the tips of the fingers and toes.

At the same time, there are scattered blisters in the mouth, such as on the lips, tongue, oral mucosa, and gums, but the blisters in the mouth quickly rupture to form small grayish white dots or a grayish white film with a red halo around it. Under the grayish white film, dot-like or flaky erosion surfaces can be seen.

What are the symptoms of hand, foot and mouth disease?

1. General symptoms

(1) Acute onset, with an incubation period of 3-5 days, and prodromal symptoms such as low-grade fever, general malaise, and abdominal pain. Scattered painful, millet- to mung-bean-sized blisters appear on the oral mucosa, and maculopapules and herpes appear on the hands and feet. Initially, they are maculopapules, which later turn into herpes. They are round or oval, about 3-7 mm in size, like the size of a grain of rice, smaller than the chickenpox rash, harder in texture, with a red halo around it, and less fluid in the blisters. Dot-like or flaky erosions can be seen under the grayish-white membrane. After the rash subsides, no scars or pigmentation are left. If there is a secondary infection, the skin damage will often be aggravated.

(2) In addition to the hands, feet and mouth, herpes can also be seen on the buttocks and near the anus, and occasionally on the trunk and limbs. They dry up and disappear after a few days. The rash is not itchy and painful.

(3) Some children may develop generalized papules and blisters, accompanied by aseptic meningitis, encephalitis, myocarditis, etc. It may be accompanied by symptoms such as cough, runny nose, loss of appetite, nausea, vomiting, and headache.

(4) Some cases only present with rash or herpetic pharyngitis. The whole course of the disease is about 5-10 days. Most cases can heal themselves with a good prognosis and no sequelae.

2. Symptoms of severe cases

In a few cases (especially those under 3 years old), encephalitis, encephalomyelitis, meningitis, pulmonary edema, circulatory failure, etc. may occur.

(1) Respiratory system manifestations include: shallow and difficult breathing, changes in respiratory rhythm, cyanosis of the lips, white, pink or bloody foamy fluid (sputum) in the mouth, and sputum sounds or moist rales in the lungs.

(2) Neurological manifestations include poor spirits, drowsiness, headache, vomiting, easy fright, limb tremors, weakness or paralysis; physical examination may reveal meningeal irritation and weakened or absent tendon reflexes; critical cases may manifest as frequent convulsions, coma, cerebral edema, and brain herniation.

(3) Circulatory system symptoms include: pale complexion, increased or decreased heart rate, shallow, rapid, weakened or even absent pulse, cold limbs, cyanosis of fingers and toes, and increased or decreased blood pressure.
