The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in the Chinese city of Wuhan in December 2019; a lockdown in Wuhan and other cities in surrounding Hubei failed to contain the outbreak, and it quickly spread to other parts of mainland China and around the world. The World Health Organization (WHO) declared a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020. Multiple variants of the virus have emerged and become dominant in many countries since 2021, with the Alpha, Beta, Gamma, Delta and Omicron variants being the most virulent. As of 1 December 2021, more than 262 million cases and 5.21 million deaths have been confirmed, making the pandemic one of the deadliest in history. COVID-19 symptoms range from none to life-threatening. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. Transmission of COVID-19 occurs when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but the virus can transmit over longer distances, particularly indoors and in poorly ventilated areas. Transmission can also occur, rarely, via contaminated surfaces or fluids. People remain contagious for up to 20 days, and can spread the virus even if they do not develop symptoms. Several vaccines have been approved and distributed in various countries, which have initiated mass vaccination campaigns since December 2020. Other recommended preventive measures include social distancing, wearing face masks in public, ventilation and air-filtering, covering one's mouth when sneezing or coughing, hand washing, disinfecting surfaces, and quarantining people who have been exposed or are symptomatic. Treatments focus on addressing symptoms, but work is underway to develop medications that inhibit the virus. Authorities worldwide have responded by implementing travel restrictions, lockdowns, business closures, workplace hazard controls, testing protocols, and systems for tracing contacts of the infected. The pandemic has resulted in severe social and economic disruption around the world, including the largest global recession since the Great Depression in the 1930s. It has led to widespread supply shortages exacerbated by panic buying, agricultural disruption, and food shortages. The resultant near-global sustained quarantine saw an unprecedented decrease in the emission of pollutants. Numerous educational institutions and public areas have been partially or fully closed, and many events have been cancelled or postponed. Misinformation has circulated through social media and mass media, and political tensions have been exacerbated. The pandemic has raised issues of racial and geographic discrimination, health equity, and the balance between public health imperatives and individual rights.

The Doji bara famine (also Skull famine) of 1791–1792 in the Indian subcontinent was brought on by a major El Niño event lasting from 1789–1795 and producing prolonged droughts. Recorded by William Roxburgh, a surgeon with the British East India Company, in a series of pioneering meteorological observations, the El Niño event caused the failure of the South Asian monsoon for four consecutive years starting in 1789.The resulting famine, which was severe, caused widespread mortality in Hyderabad, Southern Maratha Kingdom, Deccan, Gujarat, and Marwar (then all ruled by Indian rulers). In regions like the Madras Presidency (governed by the East India Company), where the famine was less severe, and where records were kept, half the population perished in some districts, such as in the Northern Circars. In other areas, such as Bijapur, although no records were kept, both the famine and the year 1791 came to be known in folklore as the Doji bara (also Doĝi Bar) or the 'skull famine,' on account, it was said, of the 'bones of the victims which lay unburied whitening the roads and the fields.' As in the Chalisa famine of a decade earlier, many areas were depopulated from death or migration. According to one study, a total of 11 million people may have died during the years 1789–1792 as a result of starvation or accompanying epidemics of disease.
