When an adult has chickenpox and has had it for 3 days, it is not advisable to go to work at this time. This is because for the vast majority of people with chickenpox, on the third day, there is still the possibility of new outbreaks of chickenpox and the vast majority of chickenpox has not scabbed over. So this time is still contagious. If you go to work, it is very likely to cause chickenpox infection, so it is not recommended to go to work. You need to isolate yourself at home until the contagiousness disappears. The disappearance of contagiousness depends on the healing of the chickenpox rash. Generally speaking, the chickenpox rash must be completely scabbed over before the contagiousness can be declared to have disappeared, and the quarantine can be lifted only at this time. Adults with chickenpox may also experience systemic symptoms, such as fever or general malaise. At this time to work, if too tired, for chickenpox disease recovery is also unfavorable. Therefore, it is not recommended to go to work on the third day of chickenpox.
