On May 3 a panel of four experts presented United Nations (UN) secretary general Ban Ki-moon with their report on the origin of the cholera epidemic that broke out in Haiti last October. As of April 21 the disease had caused 4,575 deaths, according to the Ministry of Public Health and Population (MSPP). Almost 300,000 people have contracted cholera, and the number is expected to rise as the rainy season starts.

Far-right Cuban activist Orlando Bosch died in Miami on April 27 at the age of 84. He had "a long and painful illness," according to a statement by fellow right-winger Pedro Corzo. Although accused of involvement in a number of terrorist actions targeting Cuba's leftist government, Bosch was only convicted of one: a Sept. 16, 1968 rifle attack on a Polish freighter docked at the Port of Miami. He was sentenced to 10 years in prison but fled the US after getting parole. In 1976 Venezuelan prosecutors charged Bosch and longtime US Central Intelligence Agency (CIA) asset Luis Posada Carriles in the 1976 bombing of a Cubana de Aviación jetliner; 73 people died in that attack. A Venezuelan military court acquitted Bosch and Posada in 1980, but they remained in prison pending a prosecution appeal to a civilian court. Posada escaped in 1985 and went on to work in US operations to supply the right-wing contra rebels in Nicaragua. The Venezuelan civilian court acquitted Bosch in 1987.

As of April 30 the Caribbean Community (CARICOM), the Organization of American States (OAS) and the US were all pressuring Haiti's Provisional Electoral Council (CEP) to change 18 questionable decisions in the March 20 runoff races for Parliament. On April 20 the CEP announced final results for the long-delayed second round of the 2010 presidential and legislative elections. As expected, the CEP confirmed the victory of conservative presidential candidate Michel Martelly ("Sweet Micky"). However, the final results for legislative seats changed from the preliminary count in 19 cases, and critics questioned the decisions for 18 of them: 17 seats in the Chamber of Deputies and one in the Senate. All but two of the changes awarded the seats to candidates from the centrist Unity party of outgoing president René Préval. The CEP didn't offer any explanation for its decisions, which would give Unity a majority in the 99-member Chamber and a strong position relative to president-elect Martelly, since the party already had a majority in the Senate.

Mexican president Felipe Calderón Hinojosa's militarization of the fight against drug trafficking has increased the level of violence against women, a leading Mexican feminist, María Marcela Lagarde y de los Ríos, told the Spanish wire service EFE on April 29. "Everything that is happening favors violence against women," she said. Calderón's strategy "cultivates a very violent culture" and "establishes an ideology of violence, of defeat, of war… That's a very macho culture, very misogynist, and we women are left defenseless."

Military officers in Honduras, Guatemala and El Salvador have been selling significant amounts of heavy weaponry to drug trafficking organizations in Colombia and Mexico, according to US diplomatic cables and criminal charges filed in a US court against a retired Salvadoran captain. The sales have been made possible by what US diplomats called "lax controls" by military authorities and also by the authorities' failure to bring criminal charges against officers who have been caught.

On April 8 a German development bank, DEG Deutsche Investitions- und Entwicklungsgesellschaft mbH, cancelled a previously approved loan to Grupo Dinant, a large Honduran company that produces snacks, other food products and cooking oil; the loan was reportedly worth $20 million. Shortly afterwards, EDF Trading, a wholly-owned subsidiary of the French energy firm Electricité de France SA, cancelled a contract to buy carbon credits from a Dinant subsidiary, Exportadora del Atlántico, under the Kyoto Protocol's Clean Development Mechanism (CDM) for carbon trading.

A group of activists for the rights of indigenous Mapuche Chileans interrupted the Easter mass at Santiago's Metropolitan Cathedral on April 24 to call for the release of four Mapuche prisoners who have been on hunger strike since March 15. The activists, led by the prisoners' spokesperson, Natividad Llanquileo, waited until a few minutes after the homily to begin their protest; they shouted slogans and unfurled a banner that read: "Freedom for the Mapuche political prisoners." Carabinero police agents arrived and dispersed the demonstrators; two were detained but were released later.

In Buenos Aires on April 14, Argentine federal judge María Lucía Casaín sentenced Gen. Reynaldo Bignone, the last president in the country's 1976-1983 military regime, to life in prison for crimes against humanity. The judge also handed down life sentences to former military officers Santiago Omar Riveros and Martín Rodríguez, and former Escobar mayor Luis Patti, who was a police agent under the dictatorship. Another former police agent, Juan Fernando Meneghini, was sentenced to six years in prison. The 83-year-old Bignone, who was president from July 1982 to December 1983, had already been sentenced to 25 years of prison in 2010 for crimes committed during the dictatorship in the Campo de Mayo, a military camp that included four torture centers.
