Prevention and treatment of HFMD HFMD is caused by viral infections. There are more than 20 types of enteroviruses that cause HFMD, among which coxsackievirus A16 (Cox A16) and enterovirus 71 (EV 71) are the most common. Enteroviruses are suitable for survival and transmission in hot and humid environments. The site of infection is the entire gastrointestinal tract, including the oral cavity, where it enters the body through the mouth and proliferates in the intestine. It occurs mainly under 10 years of age, more often at 3 years of age, and may also occur in adults. After infection, only immunity to this type of virus is acquired. The source of infection is herpes fluid, throat secretions, feces, contaminated hands, toys, and eating utensils. It has an incubation period of 3-8 days Clinical manifestations and diagnosis Runny nose. Runny mouth. The rash is characterized by four forms: spots, mounds, blisters, ulcers (mouth pain), four sites: mouth, hands, feet, buttocks, four no’s: no pain, no itching, no crusting, no scarring, etc. The course of the disease is 7-10 days in severe cases: it can involve the nervous system, coma, poor mental health, drowsiness, easily startled and irritable, shaking or weak limbs, paralysis and other symptoms. The symptoms include pallor, rapid heart rate, skin pattern, rapid breathing, etc., which occur 2 to 5 days after the onset of the disease and can be fatal if not treated in time. The mortality rate is extremely low, only one in 100,000 or several tens of thousands. Treatment There is no more effective treatment, take the following measures to relieve: 1. take antiviral drugs 2. keep the local clean. 3. Give easily digestible liquid food and rinse the mouth after meals. 4. Local ointment such as gentamycin and cod liver oil can be applied. 5. You can take B vitamins orally. 6. If accompanied by fever, you can use some herbal medicines to clear the heat and detoxify the toxin. The disease usually heals itself in 1 to 2 weeks without sequelae, but it is not a lifelong immunity, i.e., it can be transmitted later by fecal-oral and respiratory droplets. An epidemiological survey conducted by a city CDC shows that HFMD in children may also be transmitted to children by their parents who are recessively infected. Therefore, parents’ hygiene habits are also very important
