Varicella is a relatively common skin disease. Children usually get chickenpox during infancy. At this time, you must pay attention to care and prevent secondary infections. Generally, chickenpox has a certain self-limiting effect, which means that through certain conditioning, chickenpox will gradually improve and eventually recover. If you want to prevent infection, you can use certain medications for treatment. Chickenpox symptoms and treatment 1. Incubation period The incubation period is approximately 12 to 21 days, with an average of 14 days. 2. Early symptoms Infants and young children often have no early symptoms. Older children or adults may have fever, headache, general malaise, poor appetite and upper respiratory tract symptoms, and the rash may appear 1 to 2 days later. A prodromal rash may occasionally occur. 3. Rash period The rash appears at the same time as the fever or 1 to 2 days later, with the following characteristics: (1) The number of rashes is large, ranging from hundreds to thousands. (2) It first occurs on the trunk and head, and then spreads to the entire body. Its distribution is centripetal, with more cases on the hairline, chest and back, less cases on the limbs and face, and occasionally on the palms and soles of feet. Rashes may also occur on the mucous membranes of the nose, pharynx, oral cavity, vulva, etc. (3) The rash is often oval in shape, 3-5 mm in diameter, surrounded by a red halo, and the blisters are superficial and easy to break. The rash develops rapidly, starting as erythema, which turns into papules within a few hours and then forms blisters. The skin feels itchy during herpes and then dries into scabs. This process sometimes only takes 6 to 8 hours. If there is no infection, the scabs will fall off after 1 to 2 weeks, and generally no scars will be left. (4) The rash appears in batches, and macules, papules, blisters and scabs may be seen simultaneously in the same area. (5) Atypical varicella often develops when there are causes such as immune deficiency, coagulation disorder and secondary infection. The rash is called bullous type if it is fused and can reach a diameter of 2-7cm. It is prone to secondary Staphylococcus aureus infection and sepsis and death. The herpes is hemorrhagic, and the subcutaneous and mucous membrane ecchymoses are the hemorrhagic type, which may be accompanied by bleeding in other parts of the body. Large areas of skin necrosis and severe systemic poisoning symptoms are called necrotic type. The spread of lesions to involve internal organs is called disseminated type, which is more common in immunocompromised patients. (6) Varicella infection during the first three months of pregnancy can cause congenital malformations in the fetus, which is called congenital varicella syndrome. |
