Chickenpox is an acute respiratory transmitted infectious disease. The high incidence of chickenpox is in kindergartens, primary and secondary schools, and other group settings. The high incidence season is winter and spring, and contact with objects newly contaminated with herpes zoster virus-infected herpes fluid can put you at risk of contracting chickenpox, and contact with droplets or herpes fluid containing chickenpox-zoster virus can put you at risk of contracting chickenpox. Immunocompromised newborns, pregnant women, long-term oral immunosuppressive drugs, and patients with AIDS, diabetes, and pneumoconiosis are at high risk of contracting chickenpox. Chickenpox is extremely contagious, but after scabbing it is not contagious and rarely recurs. The virus can be latent in the body for a long time and can eventually lead to herpes zoster. After the virus occurs, it tends to cause a centripetal distribution of macules, papules and blisters.
