Overview
Urticaria
Urticaria, commonly called hives, is a skin reaction characterized by raised, itchy areas called wheals. Individual hives may appear suddenly, change in size or shape, and disappear within hours while new lesions develop elsewhere. Urticaria may be acute and short-lived or may continue or recur over a longer period. Possible triggers include infections, medicines, foods, insect exposures, physical stimuli, and immune reactions, although a specific cause is not always identified. Swelling of deeper tissues, known as angioedema, can occur along with hives.
HIV/AIDS
HIV infection is caused by human immunodeficiency virus, which attacks cells of the immune system and can weaken the body's ability to fight infections and certain cancers. Early infection may cause flu-like symptoms or no noticeable symptoms. Without effective treatment, HIV can progress to AIDS, the most advanced stage of infection. Modern antiretroviral therapy can control HIV and reduce complications.

Diagnosis
Urticaria
Urticaria is usually diagnosed clinically by examining the skin and reviewing the timing, duration, appearance, possible triggers, medicines, infections, and associated symptoms. Individual hives typically change or disappear within a relatively short period, which helps distinguish them from some other skin conditions. Laboratory testing is not routinely necessary for uncomplicated acute hives. Additional evaluation may be considered when urticaria is persistent, recurrent, associated with systemic symptoms, or when another underlying condition is suspected. Assessment for angioedema and breathing difficulty is particularly important.
HIV/AIDS
HIV is diagnosed with laboratory testing or an approved home test that detects HIV infection. Testing may involve an antigen and antibody test, an antibody test, or a nucleic acid test depending on the situation and timing of exposure. A positive screening result generally requires follow-up testing. Additional tests such as viral load and CD4 testing help assess the infection after diagnosis.
Prevention
Urticaria
Prevention of urticaria depends on whether a specific trigger can be identified. People with a known trigger may reduce episodes by avoiding that trigger when practical, while those with physical urticaria may need to limit the particular physical stimulus that causes symptoms. Medicines that have previously caused a reaction should be discussed with a healthcare professional before future use. Because chronic urticaria often has no identifiable cause, complete prevention may not be possible. Persistent or recurrent hives should be evaluated when the pattern is unclear.
HIV/AIDS
HIV prevention includes using condoms or other effective prevention methods, getting tested, and treating sexually transmitted infections. People at substantial risk can discuss pre-exposure prophylaxis with a healthcare professional, while post-exposure prophylaxis is an emergency option that must be started promptly after a possible exposure. Avoiding shared needles and maintaining effective HIV treatment also reduces transmission.
Risk Factors
Urticaria
Risk factors for urticaria depend on its type. People with allergies, certain infections, autoimmune conditions, or a personal tendency toward allergic or immune reactions may be more likely to develop particular forms. Physical urticaria can be triggered by pressure, cold, heat, sunlight, vibration, or exercise. Medicines and foods may trigger acute episodes in susceptible individuals. Chronic urticaria often has no identifiable trigger, and the presence of hives does not necessarily indicate a food allergy.
HIV/AIDS
Risk is increased by sex without effective HIV prevention methods, having another sexually transmitted infection, sharing needles or injection equipment, and exposure to infected blood. Risk can also be affected by access to testing, prevention medicines, treatment, and healthcare. People with ongoing exposure risks may benefit from discussing HIV testing and prevention options with a healthcare professional.
