Most of the scabs come off in about 6 days.

diagnose
from taking history of exposure to infection and symptoms including collecting blister samples for PCR (Polymerase Chain Reaction) delivery

smallpox vaccine
The vaccine for smallpox is called Vaccinia Virus Vaccine. Vaccine is made from the Vaccinia virus, similar to the Smallpox virus, but is less virulent. It affects the protection of 3 cases as follows:
- Get vaccinated before getting the virus can prevent disease
- Get vaccinated within 3 days of receiving the virus. Vaccines can help prevent chickenpox. But if there is a disease, the symptoms are not as severe as those who have not been vaccinated.
-Get vaccinated after 4-7 days of exposure to the virus. There is a chance of getting chickenpox. But the symptoms are milder than those who have not been vaccinated before.

smallpox medication
Cidofovir is an antiviral drug used to treat viral infections in people with HIVs. It also inhibits smallpox in vitro, but has a downside: nephrotoxicity in humans.

Tecovirimat (TPOXX) tablets
In July 2018, the US Food and Drug Administration approved Tecovirimat (TPOXX) for the treatment of smallpox. In vitro studies showed that the drug inhibited the growth of smallpox. It is effective in treating laboratory animals with diseases similar to that of smallpox. It was also tested on healthy volunteers. Only a few side effects were found, however. Both drugs have not been tested in real cases of smallpox since there is no current outbreak.
