The virus that commonly causes cold sores starts reshaping our genome within an hour of infection to boost its own growth, which scientists could take advantage of to treat severe cases.

The cold sore-causing Herpes Simplex Virus (HSV-1) hijacks human cells and reconfigures its DNA within just an hour after infection, according to a new study that may help tackle the pathogen.

Muscle aches and tiredness – more common for COVID-19 and flu – don't happen with a cold. RSV, or respiratory syncytial virus, usually causes mild symptoms akin to cold that go away on their own.
