The SARS-CoV-2 pandemic, commonly referred to as the COVID-19 pandemic, is a global health crisis caused by the novel coronavirus SARS-CoV-2. First identified in Wuhan, China, in December 2019, the virus quickly spread worldwide, prompting the World Health Organization to declare it a pandemic in March 2020.

SARS-CoV-2 primarily transmits through respiratory droplets expelled when an infected person coughs, sneezes, or speaks. Symptoms can range from mild, flu-like illness to severe respiratory distress. Common signs include fever, cough, fatigue, and loss of taste or smell. While many individuals recover without specific treatment, a significant number develop severe pneumonia and require hospitalization. The elderly and those with underlying health conditions are at higher risk of developing critical illness.

The pandemic has had profound impacts on global society, healthcare systems, and economies. Public health measures such as social distancing, mask-wearing, and lockdowns were implemented to curb transmission. The rapid development and rollout of vaccines have been a crucial element in controlling the spread of the virus and reducing the severity of illness. Ongoing research continues to monitor viral variants and refine strategies for managing the pandemic and its long-term consequences.
