Is chickenpox contagious after 12 days?

Question
Dear doctor! I have had chickenpox since the onset of the disease until today, it has been 12 days, no more blisters, only a few blisters that have not peeled off. Please ask the doctor with such a disease, can I still infect others? Looking forward to advice, thank you doctor!

Hello. Chickenpox can be spread by contact with fluid from chickenpox blisters, by breathing, and even if the blisters have crusted over. So you can still pass the disease on to others if the blisters still have the chickenpox virus. Therefore, you should take isolation measures according to the instructions to limit the possibility of infection. If your body appears abnormal, you should consult a qualified doctor for advice.
You can choose to go to the nearest facility of Vinmec International General Hospital for a more thorough examination and consultation. Thank you for submitting your question to Vinmec Health System. Best regards!
