Thank you for your query at
I understand your concern.
The contagious period, where you can spread the infection starts around 2 days before the rash appear to the day till all the blisters have at least undergone crusting. So I recommend you wait a minimum of 7 days before resuming work. 9th will be too early. I don't know why your doctor said that, some doctors believe you can resume working within 5 days after the appearance of the rash. But 7 days minimum is recommended as the body also needs time to recover.
Hope this was helpful,

Patient replied :

thanks Doc. So what exact date would you say I can work and travel then - to be specific please? are you counting from the wed 4th rash showed up, or the 2 days before (2nd). If she counted 7 days from the 2nd - that's where she got 9th I guess. thanks for the detailed help to figure.

No, I meant the contagious period starts 2 days before the appearance of the rash till all the blisters have crusted. So overall 9 days.
Meaning I advise you continue your daily activities after the 11th. By then the blisters would have crusted. Once the lesions crust, infective period ends.

Patient replied :

ok understood. And how long before spots go away totally after crusting? any tips on that?

The spots may require up to 4 weeks to perish on an average.
You can expect all the spots to disappear within a month's time.
