Do you need help? 1 TRUE Cold sores are caused by the her­pes sim­plex virus. But it’s the HSV-1 strain that causes oral cold sores, rather than HSV-2 which af­fects gen­i­tals. How­ever, it is pos­si­ble for peo­ple to get mouth cold sores through oral sex with some­one with gen­i­tal her­pes.

2 FALSE Be­fore the sore, or blis­ter, ac­tu­ally ap­pears, there’s usu­ally tin­gling in the af­fected area, pos­si­bly for a cou­ple of days, be­fore it be­comes red and swollen. Face the facts

The virus is con­ta­gious as soon as the tin­gle stage starts.

3 FALSE Once you’ve caught the virus, it’s there for life. How­ever, of­ten it re­mains ‘in­ac­tive’, which means you never de­velop cold sores and pos­si­bly don’t even know you have it. Some peo­ple might get one cold sore and never have an­other.

4 TRUE The virus is known to be highly con­ta­gious – spread through close phys­i­cal con­tact, such as kiss­ing – and it’s be­lieved that, glob­ally, around 67% of peo­ple aged un­der 50 have caught it.

5 FALSE While for some it may seem ran­dom, of­ten, for those who do ex­pe­ri­ence re­cur­ring cold sores, there are ‘trig­gers’. These in­clude be­ing run-down, be­ing oth­er­wise un­well, nutri­tional de­fi­cien­cies and some­times bright sun­light.
