Several factors contribute to blood shortages: - Seasonal Variations: During holidays or summer months, blood donations typically decline. - Epidemics and Pandemics: Events like the COVID-19 pandemic can significantly reduce blood donations due to lockdowns and fear of infection. - Natural Disasters: Natural calamities can disrupt donation drives and increase the need for blood transfusions. - Aging Population: An increasing number of elderly individuals often require more frequent blood transfusions, thus straining the existing blood supply.
