Archives (PRELIMS & MAINS Focus) Chile Syllabus Prelims – INTERNATIONAL RELATIONS/ GEOGRAPHY Context: Recently, Chile became the 95th member of the International Solar Alliance. About Chile:- IMAGE SOURCE: maps-chile.com Capital: Santiago Geography: Situated along the western seaboard of South America. Chile’s relief is for the most part mountainous, with the Andes range dominating the landscape. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the south. The Atacama desert is one of the driest places in the world that touches Chile on its northern side and is a source of sodium nitrate fertilizer. Much of northern Chile is desert; the central part of the country is a temperate region where the bulk of the population lives and where the larger cities, including Santiago, are located. South-central Chile, with a lake and forest region, is temperate, humid, and suitable for grain cultivation; and the southernmost third of the country, cut by deep fjords, is an inhospitable region—cold, wet, windy, and limited in resources. Climate and Natural events: A land of extreme natural events: volcanic eruptions, violent earthquakes, and tsunamis. Fierce winter storms and flash floods alternate with severe summer droughts. Economy: It is based on primary economic activities: agricultural production; copper, iron, and nitrate mining; and the exploitation of sea resources. Chuquicamata is the World’s largest copper town in Chile. Australia, Chile, China and Argentina are the world’s top four lithium-producing countries.

About Zika:- The Zika virus is a mosquito-borne flavivirus. It was first identified in Uganda in 1947 in monkeys. It was later identified in humans in 1952 in Uganda and the United Republic of Tanzania. Most infections in humans are asymptomatic or with mild symptoms, including fever, rash, and joint pain. Transmission:- It is primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. It can also spread through sexual contact, blood transfusion, and from an infected mother to her baby during pregnancy or childbirth. The Zika virus became notorious during the 2015-2018 outbreak that swept through the Americas. The outbreak was characterized by an alarming increase in the number of microcephaly cases in newborns, prompting the World Health Organization to declare it a public health emergency of international concern in early 2016. Treatment:- There is no vaccine or medicine for Zika. Instead, the focus is on relieving symptoms and includes rest, rehydration and acetaminophen for fever and pain.
