Manbao said, "Our Imperial Hospital also doesn't have a specific prescription. The only way to prevent and treat is to isolate the virus. Even if you come in contact, you must cover your mouth and nose, wash your hands frequently, and try to keep things that have been in contact with the sick away from your mouth and nose. Clothes, quilts, and so on should ideally be boiled before use…"
There may be some effect, but it's actually impossible to isolate completely. Smallpox is probably the most contagious disease Manbao has seen, and it survives for a long time.
After this, who knows where it will hide, perhaps in a dark corner or a speck of dust, and then, a year or so later, it attaches itself to some unlucky person and spreads again.
So to try to isolate the virus as much as possible, the method she could think of was boiling, using hot water for disinfection.
