2. World Radiography Day marks the anniversary of the discovery of X-rays in 1895. The purpose of this day is to raise public awareness of radiographic imaging and therapy, which play a crucial role in the diagnosis and the treatment of patients and, most importantly, ensuring radiation is kept to the minimum required, hence improving the quality of patient care. The day is celebrated worldwide by various national radiographers' associations and societies, including Nigeria's Association of Radiographers of Nigeria, United Kingdom's Society of Radiographers (SoR), among others.[1] The International Society of Radiographers and Radiological Technologists have celebrated 8 November as World Radiography Day since 2007.
   

World Pneumonia Day provides an annual forum for the world in the fight against pneumonia. More than 100 organizations representing the interests of children joined forces as the Global Coalition against Child Pneumonia to hold the first World Pneumonia Day on 12 November 2009.

World Diabetes Day is the primary global awareness campaign focusing on diabetes mellitus and is held on 14 November each year.

It was led by the International Diabetes Federation (IDF), each World Diabetes Day focuses on a theme related to diabetes; type-2 diabetes is largely preventable and treatable non-communicable disease that is rapidly increasing in numbers worldwide. Type 1 diabetes is not preventable but can be managed with insulin injections.Topics covered have included diabetes and human rights, diabetes and lifestyle, diabetes and obesity, diabetes in the disadvantaged and the vulnerable, and diabetes in children and adolescents. While the campaigns last the whole year, the day itself marks the birthday of Frederick Banting who, along with Charles Best, first conceived the idea which led to the discovery of insulin in 1922.
