Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection a person may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are otherwise rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss.HIV is spread primarily by unprotected sex (including anal and oral sex), contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding. Some bodily fluids, such as saliva, sweat and tears, do not transmit the virus.Methods of prevention include safe sex, needle exchange programs, treating those who are infected, as well as both pre- and post-exposure prophylaxis. Disease in a baby can often be prevented by giving both the mother and child antiretroviral medication.Known as the Berlin Patient and the London Patient, two individuals have been reported cured of AIDS and the NIH and Gates Foundation pledged $200 million focused on developing a global cure for AIDS. While there is not yet a broadly available cure or vaccine, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. Treatment is recommended as soon as the diagnosis is made. Without treatment, the average survival time after infection is 11 years.In 2020, about 37 million people worldwide were living with HIV and 680,000 deaths had occurred in that year. An estimated 20.6 million of these live in eastern and southern Africa. Between the time that AIDS was identified (in the early 1980s) and 2020, the disease has caused an estimated 36 million deaths worldwide. HIV/AIDS is considered a pandemic—a disease outbreak which is present over a large area and is actively spreading.HIV made the jump from other primates to humans in west-central Africa in the early-to-mid 20th century. AIDS was first recognized by the United States' Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade. HIV/AIDS has had a large impact on society, both as an illness and as a source of discrimination. The disease also has large economic impacts. There are many misconceptions about HIV/AIDS, such as the belief that it can be transmitted by casual non-sexual contact. The disease has become subject to many controversies involving religion, including the Catholic Church's position not to support condom use as prevention. It has attracted international medical and political attention as well as large-scale funding since it was identified in the 1980s.

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.
