The HFMD virus does not survive in the air for long, about 4-5 hours, but HFMD is a common infectious disease and is very contagious. The HFMD virus is mainly found in the stool, herpes fluid or droplets of patients, and patients with HFMD must be isolated promptly. The isolation time is about 2 weeks, until the patient’s body temperature is normal and the herpes is crusted, then you can contact with healthy people, otherwise it is easy to make normal healthy people suffer from HFMD. If you have HFMD, you should also pay attention to ventilation at home so that the virus can be removed in time.
