Huaraz ([waˈɾas]) (from Quechua: Waraq or Waras, 'dawn'), founded as San Sebastián de Huaraz, is a city in Peru. It is the capital of the Ancash Region (State of Ancash) and the seat of government of Huaraz Province. The urban area's population is distributed over the districts of Huaraz and Independencia. The city is located in the middle of the Callejon de Huaylas Valley and on the right side of the river Santa. The city has an elevation of approximately 3050 metres above sea level. The built-up area covers 8 km2 and has a population of 120,000 inhabitants, making it the second largest city in the central Peruvian Andes after the city of Huancayo. It is the 22nd largest city in Peru. Huaraz is the seat of the province's Roman Catholic Bishop and the site of the cathedral. Huaraz is the main financial and trade center of the Callejón de Huaylas and the main tourist destination of Ancash region. Moreover, is one of the biggest towns in the Peruvian Andes. Huaraz is the main destinations for winter sports and adventure. Many visitors from around the world come to the city for practicing sports as climbing, hiking, mountain biking and snowboarding, and also to visit the glaciers and mountains of the Cordillera Blanca, mainly Mount Huascarán, which is considered the tallest mountain in tropics, all of them located in Huascarán National Park which UNESCO declared a nature world heritage site. The city was founded before the Inca Empire when humans settled around the valley of the Santa River and Qillqay. Its Spanish occupation occurred in 1574 as a Spanish-indigenous reducción. During the wars for the independence of Peru, the whole city supported the Liberating Army with food and guns, earning the city the title of 'Noble and Generous City' granted by Simón Bolívar. In 1970, 95% of the city was destroyed by an earthquake that damaged much of Ancash Region. 25,000 people died. The city received much foreign assistance from many countries. For this reason the city was named a capital of International Friendship. The main economic activities in the city are farming and tourism. Since Huaraz has tourist infrastructure supporting the Ancash Highlands, the city is the main point of arrival for practitioners of adventure sports and mountaineering. Along with the snowy peaks of the Cordillera Blanca, one can visit archaeological sites like Chavín de Huantar and the eastern highlands of Ancash, known as Conchucos.

Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection a person may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are otherwise rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss.HIV is spread primarily by unprotected sex (including anal and oral sex), contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding. Some bodily fluids, such as saliva, sweat and tears, do not transmit the virus.Methods of prevention include safe sex, needle exchange programs, treating those who are infected, as well as both pre- and post-exposure prophylaxis. Disease in a baby can often be prevented by giving both the mother and child antiretroviral medication.Known as the Berlin Patient and the London Patient, two individuals have been reported cured of AIDS and the NIH and Gates Foundation pledged $200 million focused on developing a global cure for AIDS. While there is not yet a broadly available cure or vaccine, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. Treatment is recommended as soon as the diagnosis is made. Without treatment, the average survival time after infection is 11 years.In 2020, about 37 million people worldwide were living with HIV and 680,000 deaths had occurred in that year. An estimated 20.6 million of these live in eastern and southern Africa. Between the time that AIDS was identified (in the early 1980s) and 2020, the disease has caused an estimated 36 million deaths worldwide. HIV/AIDS is considered a pandemic—a disease outbreak which is present over a large area and is actively spreading.HIV made the jump from other primates to humans in west-central Africa in the early-to-mid 20th century. AIDS was first recognized by the United States' Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade. HIV/AIDS has had a large impact on society, both as an illness and as a source of discrimination. The disease also has large economic impacts. There are many misconceptions about HIV/AIDS, such as the belief that it can be transmitted by casual non-sexual contact. The disease has become subject to many controversies involving religion, including the Catholic Church's position not to support condom use as prevention. It has attracted international medical and political attention as well as large-scale funding since it was identified in the 1980s.
