2. Phase 1 – Rash
Needless to say, the primary and most noticeable symptom of chickenpox is a rash. The rash tends to spread quickly over the whole body (on and inside the mouth, included) and appears in bunches. The rash appears between 10-21 days after contacting the virus, and is transferred via contact with individuals with the rash, or through airborne transmission by coughing and sneezing.
The rash develops in 3 phases. The first phase is the rash, coming in pink or reddish bumps on the skin, that spread quickly over several days.
