A child is admitted to the hospital for an asthma exacerbation. the nursing history reveals this client was exposed to varicella (chickenpox) 1 week ago. when, if at all, would this client require isolation

This client needs to be isolated immediately because owing to the incubation of chicken pox of 2-3 weeks, the patient will be asymptomatic at this time but he can now infect other people even at 1 week post-exposure. That is why the client needs to be isolated immediately.
