Urticaria is not contagious. The course of the disease usually ranges from a few hours to several weeks. It is recommended to seek medical attention in time to determine the cause and receive proper treatment.
1. Regarding contagiousness: Urticaria is a skin problem caused by the body's internal immune response or allergy, and is not directly caused by pathogens such as bacteria or viruses. Therefore, it is not contagious between people, and there is no need to worry about daily contact.
2. Regarding recovery time: The duration of the illness varies from person to person, mainly depending on the type and triggering factors.
Acute urticaria: It usually comes on quickly and goes away quickly. The rash may subside within hours or days, but the entire course of the disease may last for several weeks.
Chronic urticaria: wheals recur repeatedly, and the course of the disease may exceed six weeks, requiring longer-term management and control.
To better manage the rash, it's recommended to keep a record of foods, environments, or activities that may trigger it, and use medications as directed by your doctor. Avoid scratching your skin, and wearing loose-fitting cotton clothing can also help relieve discomfort. If the rash is extensive or accompanied by severe symptoms such as difficulty breathing, seek medical attention immediately.
