"Is chickenpoxhighlycontagious?"
The teacher replied,"Yes, you are right. Ifthe susceptible populationswho have no immunity forchickenpoxare exposed to patients with this illness,90% of them may come down with it.Therefore, chickenpox is also known as 'face-to-face spreading'.Patientsarethe only source of infection. The viruseshidein the patient's upper respiratory tract and herpes fluid.The patient is infectious from 1-2 days from the onset of illness to the rash completely turning to scabs."
