Isolation of HFMD requires living separately, not in a common room, inside a family. If it is not possible to do so, and live in a common family or room, it is not possible to achieve effective isolation. The virus that causes HFMD is very resistant to the outside environment and can be spread by contamination on the hands or by respiratory droplets. What is even more difficult to prevent is that the HFMD virus can be spread by contamination of indirect objects. Therefore, it is difficult to achieve effective isolation when living together. The isolation period for HFMD is from the onset of the disease until two weeks after the onset of symptoms, after which the contagion is almost non-existent.
