Remember, the cold sore virus can be spread even when a person isn't showing symptoms. To avoid spreading the virus:xii Don’t touch the infected area, apart from when applying cream. Wash your hands thoroughly after touching the area. Be extra careful around children, babies, pregnant women, elderly people and those who may have low immunity, as HSV can cause complications. Don’t share items that may have come into contact with the affected area, such as toothbrushes, cutlery, cups, glasses, cold sore cream, lipsticks or lip balm. If you have cold sore symptoms, avoid kissing and oral sex until any cold sores have completely healed.
