What are the symptoms of hand, foot and mouth disease? What are the transmission routes of hand, foot and mouth disease?

Hand, foot and mouth disease is an infectious disease caused by enterovirus, which mainly occurs in infants. However, the most important way of communication is mainly close contact and communication among people, so once someone is sick, nurseries, schools and other places where children are densely populated are prone to infection.

Enterovirus infection causes hand, foot and mouth disease. According to reports, hand, foot and mouth disease is an infectious disease caused by enterovirus, which mainly occurs in infants. There are more than 20 types of enterovirus that cause hand, foot and mouth disease, mainly EV71, which is very common. The incubation period of the disease is 2 to 7 days. Generally speaking, there are no obvious prodromal symptoms before the onset of the disease. Most children develop the disease suddenly, and the fever is usually 38℃. Some children may have symptoms such as cough, runny nose, loss of appetite, nausea, vomiting, and headache. Children's hands, feet, mouth, hands, feet, oral mucosa and buttocks.

The rash is usually painless, non-itchy, and does not form scabs or scars. Because oral ulcers are painful, children often drool and refuse to eat. The rash usually subsides on its own within a week, and the body temperature also drops. Most have a good prognosis without sequelae. However, a very small number of children with hand, foot and mouth disease may have more serious complications, such as pulmonary edema, aseptic meningitis, paralysis, myocarditis, etc. Most children have a persistent high fever and the disease develops rapidly. It is common in children under 2 years old. Severe complications of the central nervous system, respiratory system, and circulatory system occur 3 to 5 days after the onset of the disease, which can lead to death.

Therefore, parents should carefully observe the physical condition of infants and young children. If they have symptoms such as fever, they should go to the hospital in time to find out health risks. Close contact between people is the main way of transmission. According to experts from the District Center for Disease Control and Prevention, although there are many ways of transmission of hand, foot and mouth disease, the main way of transmission is close contact and transmission between people. Therefore, once someone is sick, kindergartens, schools and other places where children are densely populated are prone to infection. In fact, people are often susceptible to enterovirus that causes hand, foot and mouth disease.

However, due to the improvement of their own immune system, most adults have acquired corresponding antibodies through latent infection, while children are easily infected due to poor immunity, especially those under 3 years old. The enterovirus that causes hand, foot and mouth disease can be transmitted through indirect contact with hands, towels, handkerchiefs, tooth cups, eating utensils, milk utensils, bedding, underwear, etc. contaminated by saliva, rash fluid, feces, etc.; the virus in throat secretions and saliva can be transmitted through droplets; if it comes into contact with water contaminated with the virus, it can also be transmitted through water. Cutting off the spread of the virus is one of the effective prevention and control measures.
