    ANSWER Chloroquine-resistant malaria is exactly what it sounds like—particular types of malaria which are not cured by treatment with chloroquine. Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s.

    Drug resistance has been implicated in the spread of malaria to new areas and re-emergence of malaria in areas where the disease had been eradi-cated. Drug resistance has also played a significant role in the occurrence and severity of epidemics in some parts of the world. Population movement has introduced resistant parasites to areas. Southeast Asia is the epicentre of P falciparum resistance to antimalarial drugs. Chloroquine resistance emerged there more than 40 years ago, and within 20 years chloroquine became largely ineffective. Chloroquine is now reserved for P vivax, P malariae, or P ovale in this region. In Thailand, mefloquine was introduced as first-line treatment. During the past year, confirmed chloroquine-resistant infections have been described from specific areas in Zambia 3 and Sudan 4; previously, Kenya, Tanzania, Uganda, Madagascar, and the Comoros Islands were acknowledged to have transmission of chloroquine-resistant P. falciparum.

    Since then, resistance has spread rapidly (since obviously it is beneficial to the parasite to be resistant, so various mutations conferring this protection have arisen multiple times in different areas in the world and also been passed on preferentially to new generations of malaria parasites), and now chloroquine resistant are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America. However, resistance to the drug also rapidly emerged, with the first cases of not being cured by administration of chloroquine being reported in the 1950s.

    DRUG RESISTANT MALARIA Chloroquine resistance Chloroquine is ineffective in almost all malaria endemic countries In India chloroquine resistance was first detected in 1973 in Assam. Severe in northeast and southeastern regions of India with high morbidity and mortality. The term “chloroquine resistance” can lead to misunderstandings when it is considered by some to refer to in vitro phenotypes, by others to refer to the ability of malaria parasites to survive chloroquine at therapeutic serum concentrations in vivo, and yet by others to refer to the outcome of a clinical episode after chloroquine therapy.

    CDC - Malaria - Malaria Worldwide - How Can Malaria Cases. Chloroquine-resistant P. vivax malaria was first identified in 1989 among Australians living in or traveling to Papua New Guinea. P. vivax resistance to chloroquine has also now been identified in Southeast Asia, Ethiopia, and Madagascar. Isolated reports have suggested chloroquine-resistance P. vivax in other countries and regions, but further evaluation is needed.
