In general, when an object is not contaminated with blister fluid from a person who has chickenpox, it is usually not contagious. If an object is contaminated with blister fluid, it may be contagious. Chickenpox is an acute infectious disease caused by varicella zoster virus infection, which occurs in children and is highly contagious. Clinical manifestations include fever, red spots and papules that rapidly develop into fluid-filled blisters, and other symptoms. Although highly contagious, it is a self-limiting disease and generally does not require special treatment. Chickenpox is easily spread by droplets, but can also be spread by blister fluid or objects that have been contaminated with blister fluid. When an object is contaminated with blister fluid, there is a risk of contracting chickenpox; when the object is not contaminated with blister fluid, transmission does not usually occur. You should try to stay away from people who have chickenpox or strictly do your own protection, try not to share objects, if any discomfort occurs, should go to the hospital in a timely manner, under the guidance of the doctor symptomatic treatment.
