How many days after getting chickenpox can you take a bath?

After developing chickenpox, you should usually wait until all the blisters have completely crusted over and fallen off, and the affected skin has returned to normal before taking a bath—this process typically takes about three weeks. During the course of chickenpox, the skin is broken, and bathing may allow bacteria from the water to enter, increasing the risk of infection. Additionally, patients with chickenpox often have weakened immune systems, making them more susceptible to catching a chill while bathing, which could worsen their condition.
