Symptoms and prevention of 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.

matters needing attention

1. Strict management of the source of infection: respiratory tract isolation from the beginning of rash to the end of all herpes scab, all use and respiratory secretions should be disinfected to prevent susceptible infants and pregnant women from contacting patients. 2. Protection of susceptible population: it can be vaccinated. For susceptible children and pregnant women, it can be intramuscular injected with varicella zoster immunoglobulin. Live attenuated vaccine can also prevent varicella zoster. 3. Injection of varicella vaccine: doctors generally recommend injection of varicella vaccine for infants over 1 year old. The disadvantage of this vaccine is that it may cause some side effects, and 10% - 30% of children are not fully immunized. But vaccinated children with varicella vaccine even infected with varicella, the symptoms are very mild, and some even do not rash. So if your health allows, you should be vaccinated against varicella.
