It is not allowed to see the wind when HFMD is present because HFMD is a common acute infectious disease mainly caused by a variety of enteroviruses. During the onset of the disease, the child mainly shows fever and rash. Especially when herpes is formed or there are shallow ulcers, it is not recommended to go out, and isolation should be carried out to cut off the transmission pathway and control the source of infection. Because this disease is extremely contagious, easy to develop after contact, so try to isolate, can not go out, can not see the wind. And during the onset of the child’s resistance is weak, if you go to a crowded, air-tight place or contact with patients with respiratory diseases, there may be a combination of other infections, there may be colds, bronchitis, bronchitis, and even pneumonia, etc., so isolate the child at home or hospitalize for treatment and isolation, and can not go out and see the wind.
