Causes and Symptoms
According to the Department of Health, hand, foot and mouth disease is usually caused by enteroviruses such as “Coxsackie virus” and “enterovirus 71”. Among them, hand, foot and mouth disease caused by “enterovirus 71” has attracted much attention because it is more likely to cause Serious complications such as viral meningitis, encephalitis and polio-like paralysis, and even death.
The incubation period of HFMD is about 3 to 7 days. Symptoms such as fever, loss of appetite, tiredness and sore throat usually appear at the beginning of the disease. Painful blisters may appear in the mouth 1 to 2 days after the onset of the fever. These blisters start out as tiny red spots and then develop into ulcers, usually on the tongue, gums, and inside the cheeks of the mouth. In addition, patients may develop a non-itchy and sometimes vesicular rash on the palms and soles of the feet, and even the buttocks and/or genitals. However, HFMD patients may have no symptoms, or may only have symptoms such as rashes or mouth sores.
Immunity for life after infection? Did the child get sick?
So, does being infected with hand, foot and mouth disease mean that you will be immune for life in the future? In fact, after recovering from HFMD patients, they will develop antibodies to the corresponding enteroviruses, but they can still be infected with HFMD caused by other enteroviruses in the future.
Many people think that hand, foot and mouth disease is a “children’s patent”, but in fact, people of any age can suffer from hand, foot and mouth disease. The reason why hand, foot and mouth disease is more common in children is that the disease is spread through saliva and droplets; children often put their hands in their mouths, and their hands are not hygienic, and they often have close contact with other children in school group life Contact, so they are more susceptible than adults.
According to the Red Cross, many infected children have difficulty swallowing due to the many blisters in their mouths. Parents can give them some cool food, such as frozen milk, cheese, jelly and ice cream, etc. In addition, children may also vomit due to hand, foot and mouth disease. Since there are many viruses in the vomit, when the vomit contaminates some places or objects, it is easy to cause virus residues. If it is not disinfected, other people will also be infected. It is recommended to use 1:49 diluted household bleach for cleaning.
Currently, there is no specific medicine to treat HFMD. Patients should drink plenty of water and have adequate rest. Medicines can also be used to treat symptoms and relieve pain caused by fever and mouth ulcers. To avoid spreading the virus to others, patients should avoid going to school or participating in group activities until all blisters dry up. If the infection is caused by Enterovirus 71, the patient should stay at home for two weeks before returning to work or school after full recovery (i.e. fever and rash subside, and all blisters dry up and crust over).
Attention daily hygiene
As there is still no vaccine to effectively prevent HFMD, it is most important to maintain good personal and environmental hygiene to effectively prevent infection. Members of the public should keep their hands clean, wash their hands with liquid soap and water before eating, cover their mouth and nose with tissues when sneezing or coughing, avoid sharing food or drinks with others, and avoid sharing towels or other personal items. In terms of environment, in addition to maintaining indoor air circulation, it is also recommended to use 1:99 diluted household bleach for daily cleaning, and to clean frequently touched places and objects.
