Antiretroviral therapy (ART) is important in prolonging life and reducing complications in patients with HIV infection. This applies to any country and Africa is no exception. As depicted by graduated colours, Botswana and Rwanda have achieved the target of universal access by providing more than 80% of the patients in need with ART. However, the estimated ART coverage has remained below 50% in most other African countries.

In the same map, the cross symbol shows the accessibility to HIV prevention, treatment, care and support for vulnerable subpopulations in 2010. As reported by the government and civil society of each country, obstacles in form of laws, regulations or policies are more common in Southern Africa, where more efforts are required before universal access can be achieved. This in fact is the theme of World AIDS Day 2010.

Data for the map is obtained from World Health Organization and UNAIDS.

What is HIV/ AIDS? 什麼是人類免疫力缺乏病毒感染/愛滋病?

  • The human immunodeficiency virus (HIV) is a retrovirus that infects cells of the human immune system, destroying or impairing their function. In the early stages of infection, there is no symptom. As HIV infection progresses, the immune system becomes weaker, thereby increasing susceptibility to opportunistic infections.
  • The most advanced stage of HIV infection is acquired immunodeficiency syndrome (AIDS). In the absence of treatment, 50% of the infected individuals progress to AIDS. The use of antiretroviral drugs can reverse the immune deficiency.
  • 人類免疫力缺乏病毒(HIV)是一種感染人類免疫細胞,從而破壞人體免疫系統的反轉病毒。在感染初期,患者可以完全沒有任何病癥。但在感染後期,患者的免疫力會被削弱,容易被其它機會性感染影響。
  • 愛滋病(後天免疫力缺乏症候群) 是人類免疫力缺乏病毒感染的後期嚴重階段。在沒有接受治療的情況下,平均一半感染者在十年內發病,成為愛滋病患者。抗病毒藥物治療可以有效恢復患者免疫能力。

How does HIV spread? 如何傳播?

  • HIV is transmitted through unprotected sexual intercourse (heterosexuals and homosexuals), transfusion of contaminated blood or blood products, sharing of contaminated needles in injection drug users, and between a mother and her infant during pregnancy, childbirth and breastfeeding.
  • HIV的傳播途徑包括不安全性接觸 (異性及同性) ,輸入受污染血液或血制品、靜脈吸毒者共用針筒、和母嬰傳播(懷孕、分娩、和哺乳期間)。

Vaccine? Prevention? 如何預防?

  • A safe and effective vaccine is still under development. The practice of safer sex with the use of condom is one most effective means of preventing HIV infection through sex. Avoidance of needle sharing is important in injection drug users, whereas antiretroviral treatment can be effective in preventing mother-to-child HIV transmission.
  • 預防疫苗至今仍在研究中。現時最有效的預防性傳播方法是採用安全性行為,包括使用安全套。吸毒者應避免共同使用針具,而抗病毒藥物則可以有效預防母嬰傳播。

HIV-related stigma and discrimination 愛滋病相關的標籤及歧視

Stigma and discrimination might make people living or associated with HIV and AIDS less likely to test for the infection, disclose one's HIV status, adopt HIV preventive measures or have access to treatment. They are therefore barriers to effective responses to HIV.

World AIDS Day falls on the 1st of December every year. For 2009-2010, the theme is "Universal Access and Human Rights", drawing global attention to human rights of people living with HIV and vulnerable population, mobilizing support for universal access of HIV prevention, treatment, care and support and combating stigma and discrimination.
