Every time the weather gradually, kindergartens and elementary schools will begin to focus on hand, foot and mouth disease, and other diseases are not quite the same place, the spread of hand, foot and mouth disease mostly occurs in kindergartens, this is because the early symptoms of this disease is relatively mild, children and adults are easy to ignore, and this time is more contagious, children who still go to kindergarten normally, it is easy to infect other children, and hand, foot and mouth and can be transmitted through the respiratory tract, the Hand, foot and mouth can be transmitted through the respiratory, contact and digestive tracts, so it is particularly easy to have an epidemic outbreak in child care institutions. This is the reason for the special concern of child care institutions, once it appears, they have to suspend classes to disinfect the environment. Parents are concerned about hand, foot and mouth disease, mainly because they are worried about encephalitis. Whether it is anecdotal or official reports, words such as encephalitis and sudden death are mentioned. Many critical cases of HFMD, from diagnosis to death, may only be half a day or even a few hours. When parents bring their children with HFMD to the hospital, doctors also tend to inform parents that the most serious complication of HFMD is encephalitis, which may result in severe HFMD or even become critical HFMD. So what is the real situation of HFMD? Are doctors alarmist or is it really so terrible? There is good news and there is bad news. The good news is that HFMD is not as scary as you might think, and although doctors are not alarmist, they are suspected of overstating the case. Of course, a more responsible doctor will tell you what the average probability of various conditions is. For example, in 2014, 2778,861 cases of HFMD were reported nationwide, with 501 deaths, a death rate of 0.18 per 1,000, or 2 in 10,000, which some may think is a high probability, but considering that the actual number of HFMD cases should be higher than the reported cases, because most children with minor illnesses are not seen and reported, the actual death rate should be much lower than this figure. In 2013, 1828,377 HFMD cases were reported nationwide, with 252 deaths, a death rate of 0.13 per 1,000, so the probability of death due to HFMD is really the “what-if” probability that everyone is talking about. The bad news is that doctors can’t predict which HFMD child is the “what-if”. And a large number of papers on HFMD published in professional journals every year, focusing on how to detect critical cases early papers are also many. In general, if the child has persistent high fever, especially if antipyretic drugs are ineffective, has easy fright, involuntary shaking of the limbs, depression, drowsiness, or restlessness, frequent vomiting, elevated white blood cells and elevated blood sugar in laboratory tests, there is a high possibility of serious cases. If the heart rate increases, blood pressure rises and the respiratory rhythm changes, the possibility of a critical case is higher. The diagnosis of HFMD relies on clinical symptoms, and fever with herpes on the hands, feet, mouth and buttocks is typical. During the epidemic season, parents can watch for rashes in these areas. Regarding the treatment of HFMD, in contrast, it is relatively simple, with severe cases staying in the hospital for observation and treatment, and critical cases needing to be admitted to the intensive care unit for observation and treatment. For common HFMD, isolation at home to avoid infecting other children, symptomatic treatment at home is sufficient, fever is given to reduce fever, and if there is herpes in the oropharynx, it may be difficult to eat due to pain, so avoid giving overly hot food or acidic drinks to aggravate ulcers and pain. Cold drinks can partially relieve the pain. No specific medication has been found for HFMD. There is no need for parents to appear psychologically comfortable giving other medications. The HFMD vaccine will be available soon, but prevention is still the main focus. It should be noted that because there is more than one virus that can cause HFMD, HFMD is not a lifelong immunity, and having had HFMD once, HFMD may occur again the next time you get infected with another virus.
