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 Bengal Famine of 1770 (Bengali: Chiẏāttôrer mônnôntôr, lit. The Famine of 76) was a famine that struck the Bengal region between 1769 and 1770 (1176 to 1177 in the Bengali calendar) and affected some 30 million people. It occurred during a period of dual governance in Bengal. This existed after the East India Company had been granted the diwani, or the right to collect revenue in Bengal by the Mughal emperor in Delhi, but before it had wrested the nizamat, or control of civil administration, which continued to lie with the Mughal governor, the Nawab of Bengal.Crop failure in autumn 1768 and summer 1769 and an accompanying smallpox epidemic were thought to be the manifest reasons for the famine. The Company had farmed out tax collection on account of a shortage of trained administrators, and the prevailing uncertainty may have worsened the famine's impact. Other factors adding to the pressure were: grain merchants ceased offering grain advances to peasants, but the market mechanism for exporting the merchants' grain to other regions remained in place; the Company purchased a large portion of rice for its army; and the Company's private servants and their Indian Gomasthas created local monopolies of grain. By the end of 1769 rice prices had risen two-fold, and in 1770 they rose a further three-fold. In Bihar, the continual passage of armies in the already drought-stricken countryside worsened the conditions. The Company provided little mitigation through direct relief efforts; nor did it reduce taxes, though its options to do so may have been limited.By the summer of 1770 people were dying everywhere. Although the monsoon immediately after did bring plentiful rains, it also brought diseases to which many among the enfeebled fell victim. For several years thereafter piracy increased on the Hooghly river delta. Deserted and overgrown villages were a common sight. Depopulation, however, was uneven, affecting north Bengal and Bihar severely, central Bengal moderately, and eastern only slightly. The recovery was also quicker in the well-watered Bengal delta in the east.Between seven and ten million people—or between a quarter and third of the presidency's population—were thought to have died. The loss to cultivation was estimated to be a third of the total cultivation. Some scholars consider these numbers to be exaggerated in large part because reliable demographic information had been lacking in 1770. Even so, the famine devastated traditional ways of life in the affected regions. It proved disastrous to the mulberries and cotton grown in Bengal; as a result, a large proportion of the dead were spinners and weavers who had no reserves of food. The famine hastened the end of dual governance in Bengal, the Company becoming the sole administrator soon after. Its cultural impact was felt long afterwards, becoming the subject a century later of Bankim Chandra Chatterjee's influential novel Anandamath.
