A pandemic is a global outbreak of a disease that occurs when a new virus or pathogen emerges among humans, causing serious illness and spreading easily from person to person[1].


Historical Context

Throughout history, several pandemics have had a significant impact on human societies, including the Black Death in the 14th century, the Spanish flu in 1918, and most recently the COVID-19 pandemic caused by the SARS-CoV-2 virus in 2019[2].

Factors Contributing to Pandemics

Several factors contribute to the emergence and spread of pandemics, including increased global travel and trade, urbanization, changes in land use, and climate change[3].

Pandemic Preparedness and Response

Pandemic preparedness involves proactive planning and investment in public health infrastructure, surveillance systems, research and development, and healthcare capacity. The World Health Organization (WHO) plays a critical role in coordinating global efforts during pandemics[4].
