Explanation:
Detailed explanation-1: -After inhalation, chickenpox viruses invade the cells of the respiratory tract, replicate in the lymph nodes and are spread by white blood cells throughout the body. Eventually, they lodge in the skin, causing the itchy blisters that are characteristic of the disease.
Detailed explanation-2: -Chickenpox can be more serious in adults than in children. Adults with the virus are more likely to be admitted into hospital. Approximately 5-14% of adults with chickenpox develop lung problems, such as pneumonia. If you smoke, your risk of developing lung problems is much higher.
