Hi,

Cold sore..herpes simplex labialis is a viral infection caused by HSV virus.

It is an infection, so it is contageous.

And remember, it is not totally cured at a time.

Even after lesions subside, the load of virus remains there for long time. So, you get relapses. Therefore, it is not advisable to have kiss of lips for long time.

You should take antiviral ..acyclovir in proper doses for few months.

Immunobusters may be taken to improve immunity.

Avoid worries,have healthy food and proper sleep.

I hope you got my answer.

Thanks.
