Dating a girl with oral herpes
You can also catch herpes from someone who has no visible herpes sores.About 3% of people carry the virus on their skin without knowing that they have it (because it has never given them any symptoms), but they can pass it on to other people.
First genital infection with herpes simplex virus causes sores ↓ Herpesvirus travels up nerves to the nerve ganglion where it lies low ↓ At a later date, herpesvirus may travel down nerves to the genital skin, causing a ‘recurrent attack’ of herpes ↓ Recurrent attack heals, and herpesvirus retreats to the ganglion again ↓ At a later date, herpesvirus may travel down to the genital skin again, causing another recurrent attack.
The stage with painful sores will usually last about 4 days, and it will all be over in about 10 days.
Some recurrent attacks are so minor that they are almost unnoticeable just slight irritation of soreness.
When it reaches the clusters of cells at the end of the nerves (called ganglia), it stops travelling.
The herpesvirus DNA then remains quietly in the ganglia.
