Chickenpox is a highly contagious rash disease caused by varicella zoster virus infection, and is highly prevalent in children under 14 years of age. In other words, the patient’s whole body chicken pox scabs off, even if cured. How long does it take to heal from the onset of the disease? Most children have mild symptoms and rash, and they recover in about 2 weeks for mild cases. In newborn infants, adults, immune deficiencies, patients with chronic underlying diseases or glucocorticoid use, varicella is often severe, with a high mortality rate and a correspondingly prolonged course of 3 weeks or longer. In a few cases, the course of the disease is longer due to the combination of pneumonia or encephalitis, but most patients can be cured with timely treatment. The current treatment of chickenpox includes symptomatic treatment such as antipruritic and antipyretic treatment and antiviral treatment. In people with normal immunity, chickenpox can heal on its own and does not require treatment, but you need to avoid secondary bacterial infections after chickenpox breaks, especially do not scratch the infection, keep the skin clean and use antibiotic ointment promptly if there is a risk of infection.
