The incidence rate is highest in children under 4 years of age.
Hand, foot and mouth disease is a non legally reported infectious disease caused by children infected with enterovirus EV71. It mostly occurs in infants under the age of 5 and can cause fever, rash and ulcer on hands, feet and mouth. Chen Liming said that hand, foot and mouth disease is a common infectious disease in infants and young children, which is caused by enterovirus. The crowd is generally susceptible to hand foot mouth disease virus, but the incidence rate of preschool children is especially high in age group 4 and below, accounting for 85%-95%. The incubation period is about 2 to 7 days.
According to Wei Hong, deputy chief physician of Pediatrics of Tongren Hospital, due to herpes pharyngitis and other diseases, there will be similar rash and ulcer symptoms. Many parents are easy to confuse these diseases. Wei Hong reminded that if the child’s hands, feet, mouth and perianal rash and ulcer symptoms are found at the same time, it is likely to be hand, foot and mouth disease, and should be treated immediately.
Kindergartens are the main places for prevention
Chen Liming said that patients with hand, foot and mouth disease, latent infections and asymptomatic carriers are the main sources of infection. It is mainly transmitted through close contact between people.
The virus in the patient’s throat secretion and saliva can infect others in the form of droplets; The virus in herpes fluid and feces can also be transmitted to others. The water source polluted by the virus can also be transmitted by mouth and often cause transmission. At present, there is no special prevention method for hand, foot and mouth disease, and there is no specific drug to treat it. Therefore, it is very important to prevent isolation.
