World Health Day is the birthday of the World Health Organization (WHO) and a day that is close to Emmanuel Eraly's heart, as he has been involved in many campaigns to raise awareness of health issues in Viet Nam, where he worked for almost four years as a UNV intern and later as an international UN Volunteer supporting the communications function of WHO.

Port of Spain, Trinidad and Tobago: I was documenting medical history from a newly diagnosed HIV-positive patient, accompanied by his very caring wife, when they told me how much they loved to dance every weekend before they got ill. The couple returned after a fortnight, but to my astonishment their medical file bore an older clinical number and was considerably heavier in content. Although it had the same last name, the clinical number was about 4 years old.

Kankan, Upper Guinea; Guinea-Conakry: When I took up the role of the UN Youth Volunteer for the High Commissioner for Human Rights, I was not quite sure what to expect. "From the university benches, past lectures and books to the real-life practice of human rights on the field." These words are what come to mind when I try to summarise those three weeks on mission to monitor human rights in Guinea.

Darfur, Sudan: In 2009, I joined UNAMID as a volunteer HIV and AIDS trainer/counsellor, after having served as a VSO volunteer HIV and AIDS advisor in Cambodia, and as an HIV and AIDS counsellor with TASO in my own country of Uganda. I am passionate about volunteering, having started work as a volunteer in Uganda, and born in a family of volunteers - my father and mother were community volunteers helping those in need.

Tashkent, Uzbekistan: Few people realize that, although currently there is no cure for HIV, the existing medicine has turned HIV into a chronic disease, with which HIV-positive people can and do live long, productive, flourishing lives, and have HIV-negative partners and children. Moreover, if taken correctly, modern medicine minimizes the risk of HIV transmission to others and allows partners to take preventative medicine. Yet, misunderstanding and stigma persist.

Monrovia, Liberia: Living through the Ebola epidemic in Liberia, I observed first-hand what was achieved by the global community. By complementing local efforts, it controlled and contained what could have otherwise become another viral infectious disease of global epidemic proportions. The key actions that contributed to the successful control of the Ebola epidemic in West Africa were essentially the prompt actions taken by the UN to marshal resources and other stakeholders to control the spread of the virus.

Darfur, Sudan: When I started volunteering in Darfur with the African Union-United Nations Hybrid Operation in Darfur (UNAMID) as an HIV/AIDS Trainer/Counselor, my responsibilities included carrying awareness training, counselling and testing. I worked with other UNAMID sections, other peacekeepers and internally displaced persons. The exposure and ownership that I've been given over the projects, as well as the time and responsibility that I've been given from professionals that I've worked with has been overwhelming.

Darfur, Sudan: Fighting the spread of HIV in war zones and conflict settings is a major challenge facing UN Missions across the globe. The conflict in Darfur has resulted in huge displacements of populations, disruption to family structures and livelihoods, as well as the deterioration of health infrastructures. Additionally, it has led to the creation of camps for internally displaced persons (IDPs) across the region. In general, the spread of HIV/AIDS is exacerbated by conditions of violence and instability that increase the risk of exposure to the disease.
