Food safety is a shared responsibility between governments, producers and consumers. Everybody has a role to play from farm to table to ensure the food we consume is safe and will not cause damages to our health. Through the World Food Safety Day, WHO pursues its efforts to mainstream food safety in the public agenda and reduce the burden of foodborne diseases globally.

When a health facility's "quality and safety climate or culture" values hand hygiene and infection prevention and control (IPC), this results in both patients and health workers feeling protected and cared for. 

To prioritize clean hands in health facilities, people at all levels need to believe in the importance of hand hygiene and IPC to save lives, by acting as key players in achieving the appropriate behaviours and attitudes towards it. In other words, health workers at all levels and people accessing health care facilities need to unite on ensuring clean hands.

World Hearing Day is held on 3 March each year to raise awareness on how to prevent deafness and hearing loss and promote ear and hearing care across the world. Each year, WHO decides the theme and develops evidence-based advocacy materials such as brochures, flyers, posters, banners, infographics and presentations, among others. These materials are shared with partners in government and civil society around the world as well as WHO regional and country offices. At its headquarters in Geneva, WHO organizes an annual World Hearing Day event.

World AIDS Day brings together people from around the world to raise awareness about HIV/AIDS and demonstrate international solidarity in the face of the pandemic.

Celebrated annually, the World Antimicrobial Awareness Week (WAAW) aims to increase awareness of global antimicrobial resistance and to encourage best practices among the general public, health workers and policy makers to avoid the further emergence and spread of drug-resistant infections.

World Patient Safety Day calls for global solidarity and concerted action by all countries and international partners to improve patient safety.

The Day brings together patients, families, caregivers, communities, health workers, health care leaders and policy-makers to show their commitment to patient safety.

World Hepatitis Day, 28 July, is an opportunity to step up national and international efforts on hepatitis, encourage actions and engagement by individuals, partners and the public and highlight the need for a greater global response as outlined in the WHO's Global hepatitis report of 2017.

The date of 28 July was chosen because it is the birthday of Nobel-prize winning scientist Dr Baruch Blumberg, who discovered hepatitis B virus (HBV) and developed a diagnostic test and vaccine for the virus. 

Every year countries around the world celebrate World Blood Donor Day (WBDD). The event serves to raise awareness of the need for safe blood and blood products and to thank voluntary, unpaid blood donors for their life-saving gifts of blood.

A blood service that gives patients access to safe blood and blood products in sufficient quantity is a key component of an effective health system. The global theme of World Blood Donor Day changes each year in recognition of the selfless individuals who donate their blood for people unknown to them.

This yearly celebration informs the public on the dangers of using tobacco, the business practices of tobacco companies, what WHO is doing to fight the tobacco epidemic, and what people around the world can do to claim their right to health and healthy living and to protect future generations.
