The COVID-19 pandemic was a global health crisis caused by the novel coronavirus, SARS-CoV-2. First identified in Wuhan, China, in late 2019, the virus rapidly spread worldwide, leading the World Health Organization (WHO) to declare it a pandemic in March 2020.

The disease, COVID-19, primarily affects the respiratory system, with symptoms ranging from mild, flu-like illness to severe pneumonia and death. Transmission occurs mainly through respiratory droplets expelled when an infected person coughs, sneezes, or talks. Public health measures, including social distancing, mask-wearing, and frequent handwashing, were implemented to curb the spread.

The pandemic had profound global impacts, including widespread illness and death, significant strain on healthcare systems, and severe disruption to economies and daily life. Lockdowns, travel restrictions, and business closures became common.

In response, scientists rapidly developed vaccines and treatments. Vaccination campaigns began in late 2020 and early 2021, significantly reducing severe illness and mortality rates. Ongoing research continues to monitor the virus and its variants, and public health strategies adapt to evolving circumstances. The long-term effects of the pandemic, both health-related and societal, continue to be studied and addressed.
