I have recently been transferred to work in an HFMD critical care area. The outbreak is still heavy. Beds are full. Parents take HFMD very seriously and even worry a little too much about it. In fact, HFMD is a viral infection, the main virus is the enterovirus EV71, coxsackievirus 16, which has been around for a long time. In the past few years, the epidemic is widespread, more serious cases, more deaths than before. The disease can develop throughout the year, with a high incidence in summer. The vast majority of patients are not at risk. Most of the severely ill patients are younger than 3 years old. For some children with only oral herpes – diagnosed as herpes pharyngitis, it is also important to pay attention to it, which can also become severe and infectious, and the virus is of the same group. Some children can show only oral herpes, and some initially have herpes pharyngitis, which later develops into hand, foot and mouth disease. The key to family prevention is to pay attention to: hand hygiene, dietary hygiene, more ventilation, less going to public places, and especially to avoid contact with sick children. When you get HFMD, go to a hospital at or above the county level in a timely manner. Make a clear diagnosis. At present, there is no special treatment drug. You can take Ribavirin, Pudilan Oral Liquid, Blue Scutellaria Oral Liquid, etc. orally. Fever patients can be treated by oral or intravenous infusion. Outpatient or inpatient treatment can be observed. The key to the treatment of HFMD is the timely detection of early manifestations of severe disease. Parents should pay attention to the main points of observation: persistent high fever, cold limbs, fast breathing, drowsiness, poor mental health (when not feverish), easy frightening, shaking limbs, frequent vomiting, etc. If one of these conditions occurs, go to the hospital immediately. If you are treated in the hospital, inform the medical staff promptly.
