Initial symptoms of mild varicella?

The incubation period of the disease was 12-21 days, with an average of 14 days. Older children and adults may have fever, headache, general tiredness, nausea, vomiting, abdominal pain and other precursor symptoms before the rash, while children may have rash and systemic symptoms at the same time.

The rash appeared within 24 hours after the onset of the disease. The rash first occurred in the compressed part of the scalp and trunk, and presented centripetal distribution. At the beginning, it was a small pink rash, which quickly turned into a round tension blister with the size of rice to pea. There was obvious red halo around the blister, and the central part of the blister was in the shape of umbilical fossa. The mucous membrane is often invaded, such as oral cavity, pharynx, conjunctiva, vulva and anus.

During the rash period of 1-6 days, the rashes appeared in batches, and the lesions showed the evolution process from small red macular papules to herpes, scab formation to decrustation. No scar was left after decrustation. Blister stage itching is obvious, if scratch secondary infection can leave a slight dent. About 4% of adults may have disseminated chickenpox and chickenpox pneumonia.
