It’s hand, foot and mouth disease season again (May-July and October-December every year)! Today I’m here to spread the word about HFMD. First of all, let’s set the tone: HFMD is not a beast and there is no need to cause panic. However, it should not be taken lightly. Because we see thousands of HFMD each year, only a small percentage requires hospitalization, but every year there are several severe cases with serious consequences. Hand, foot and mouth disease is an enterovirus infection resulting in infectious diseases, generally infecting preschoolers, more than ninety percent of the dolls under the age of five, and the most of them are under the age of three. Hand, foot and mouth disease, just listen to the head to know that it is to cause the doll’s hands, feet and mouth problems. In addition to the usual fever, mental and dietary decline caused by viral infections, HFMD has its own typical manifestations: herpes on the palms of the hands, feet and oral mucosa. The typical herpes is a round-like blister with cloudy water inside the blister and a ring of redness around the blister; the blister in the mouth breaks and becomes an ulcer. The distribution is usually only on the palms of the hands, feet and fingers, and hardly ever grows on the skin of the back of the hands and feet. A few dolls have red papules around the knees and anus. The herpes of HFMD has “eight no’s”: not painful, not itchy, not broken (except in the mouth), not crusted, not like allergies, not like chicken pox, not like mosquito bites, not like mouth, gingivitis. That person said, you said that HFMD is an infectious disease, so how does it run from one doll to another? I am about to introduce it here. First of all, nature has the existence of intestinal viruses, lurking at any time waiting to infect any doll who does not wash his hands, so that through him to carry forward his family. When the human body, the virus will be in the mouth, hands, feet in the herpes to multiply by tens of thousands of millions. The infected doll becomes a virus seeding machine, the mouth, hands and feet of the herpes, poop are alive and well in the virus. Where to pull, touch where to bring the virus. Good dolls and sick dolls to play, if you play a rascal kissed her or pulled her hand, touched the food she ate, played with toys, touched things, used towels will touch the virus on the hands, then if you do not wash your hands and eat, the virus will eat with the food into the stomach, the doll is infected, and then become a virus dispersal center, through play, poop and spread the virus to the surrounding environment The virus then becomes a dispersal center, spreading the virus back to the surrounding environment through playing and pooping, infecting other dolls. This is the reason why the disease can break out in kindergartens and other childcare facilities. Hand, foot and mouth disease, like many other viral infectious diseases have two characteristics: self-limiting, that is, no medical treatment will also be good, the second is no specific treatment, of course, not that the disease can not be treated, but that there is no special anti-hand, foot and mouth disease virus drugs, we deal with hand, foot and mouth disease through symptomatic support treatment methods. The vast majority of HFMD is mild, with a relaxed presentation and a good prognosis, recovering within a week. However, a very small number of severe cases can lead to encephalitis, encephalomyelitis, brainstem inflammation, pulmonary edema, circulatory collapse, and death or serious sequelae if resuscitation is not successful. This is what determines the importance of prevention and control of hand, foot and mouth disease, once suffering from hand, foot and mouth disease, regardless of light, heavy, must go to the regular hospital consultation. Some families still have doubts, how to know whether the baby is suffering from light or heavy? Will the mild form develop into a heavy form? There are no precursors? This, at present, there is no standard. However, after our observation of severe HFMD over the years, we have summarized a few points. Any doll under 3 years old with HFMD who shows the following signs has an increased risk of getting heavy HFMD: 1. high fever that does not subside, temperature above 39℃, and does not drop to normal for more than 6 hours 2. irritability, agitation, convulsions, involuntary jumping of limbs or even jerking as if in shock. 3.Mental depression, and the general cold obviously does not match the mental depression. 4. Repeated vomiting, vomiting non-stop even when eating or not eating. 5.Shortness of breath, blue lips and mouth. 6, routine blood test leukocytes exceed 15×109/l As with all pediatric diseases, prevention is important: pay attention to hygiene, strengthen nutrition, eat less raw food, wash hands before eating, and avoid playing with public toys in children’s playgrounds during the epidemic season. The treatment of this disease is not recommended to buy your own medicine without seeing a doctor, so I won’t go into the treatment options here. It does not matter if you see a lot of words and have a short reading fetish, just remember the last sentence. If you suspect that your child has hand, foot and mouth disease, see a doctor immediately at the pediatric herpes clinic of a regular hospital infection department.
