International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.

World Hepatitis Day 2025
World Hepatitis Day is marked to increase the awareness and understanding of viral hepatitis and the diseases that it causes. It provides an opportunity to focus on specific actions such as:
- strengthening prevention, screening and control of viral hepatitis and its related diseases

Hepatitis viruses A, B, C, D and E can cause acute and chronic infection and inflammation of the liver leading to cirrhosis and liver cancer. These viruses constitute a major global health risk.

Bone Marrow Stem Cell Donation and Leukaemia Awareness Month 2025
Leukaemia is a group of bone marrow diseases involving an uncontrolled increase in white blood cells (leukocytes). There is around a 30% chance of a sibling being a bone marrow match, meaning that there is a 70% chance that someone will need a transplant from a non-related donor. Each year, 35 people in every million learn that they have leukaemia of whom five will be children.
As opposed to a few different blood types, there are millions of different types of cell tissue. The success of a patient’s transplant depends on finding a match, otherwise their body will reject it.
DKMS Africa was formed in 1999 to create awareness for the need of donors. It was formed by parents whose children had contracted leukaemia, and in some cases had lost their battle against it.
