“…In this review, we agree with the conclusion of von Seidlein 2003 that MDA was generally unsuccessful in interrupting transmission but had a marked effect on parasite prevalence and on the incidence of clinical malaria in some cases. The von Seidlein 2003 review also proposed a role for MDA in the control of epidemics and in the control of malaria in areas with a short transmission season, which this current review did not specifically address.…”

“…Antimalarial drug use for MDA has been reviewed previously (Greenwood 2004; von Seidlein 2003). Thirteen of the studies in this current review (Cavalie 1962 CMR; De Zulueta 1961 UGA; De Zulueta 1964 UGA; Escudie 1962 BFA; Garfield 1983 NIC; Hii 1987 MYS; Kaneko 2000 VUT; Kondrashin 1985 IND; Molineaux 1980 NGA; Najera 1973 NGA; Roberts 1964 KEN; Singh 1953 IND; von Seidlein 2003 GMB) were also included in a review of MDA of antimalarial drugs published in 2003.…”

However, several studies included in the von Seidlein 2003 review were excluded from this review. The main reasons for exclusion were: 1) inadequate treatment doses (Barber 1932; Dola 1974; MacCormack 1983; Onori 1972; Strangeways-Dixon 1950); 2) individually randomized (Doi 1989); 3) insufficient information on outcomes of interest (Yip 1998); and 4) insufficient information on drug administration (Baukapur 1984; Lakshmanacharyulu 1968; Sehgal 1968).…”

“…While the aim of early antimalarial drug distribution studies was to interrupt transmission, this was rarely accomplished. The empiric use of antimalarial drugs to prevent malaria can be generally grouped into three, sometimes overlapping categories: 1) chemoprophylaxis, where drugs are administered at suppressive doses throughout the defined period; 2) intermittent preventive treatment (IPT), where a full curative dose of an antimalarial is given to a target population at specified times; or 3) MDA, where drugs are administered to the whole population either using full therapeutic courses, known as direct MDA, or through the fortification of dietary salt, known as indirect MDA (Greenwood 2004; von Seidlein 2003). …”

Background Mass drug administration (MDA), defined as the empiric administration of a therapeutic antimalarial regimen to an entire population at the same time, has been a historic component of many malaria control and elimination programmes, but is not currently recommended. With renewed interest in MDA and its role in malaria elimination, this review aims to summarize the findings from existing research studies and program experiences of MDA strategies for reducing malaria burden and transmission. Objectives To assess the impact of antimalarial MDA on population asexual parasitaemia prevalence, parasitaemia incidence, gametocytaemia prevalence, anaemia prevalence, mortality and MDA‐associated adverse events. Search methods We searched the Cochrane Infectious Disease Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE+, EMBASE, to February 2013. We also searched CABS Abstracts, LILACS, reference lists, and recent conference proceedings. Selection criteria Cluster‐randomized trials and non‐randomized controlled studies comparing therapeutic MDA versus placebo or no MDA, and uncontrolled before‐and‐after studies comparing post‐MDA to baseline data were selected. Studies administering intermittent preventive treatment (IPT) to sub‐populations (for example, pregnant women, children or infants) were excluded. Data collection and analysis Two authors independently reviewed studies for inclusion, extracted data and assessed risk of bias. Studies were stratified by study design and then subgrouped by endemicity, by co‐administration of 8‐aminoquinoline plus schizonticide drugs and by plasmodium species. The quality of evidence was assessed using the GRADE approach. Main results Two cluster‐randomized trials, eight non‐randomized controlled studies and 22 uncontrolled before‐and‐after studies are included in this review. Twenty‐two studies (29 comparisons) compared MDA to placebo or no intervention of which two comparisons were conducted in areas of low endemicity (≤5%), 12 in areas of moderate endemicity (6‐39%) and 15 in areas of high endemicity (≥ 40%). Ten studies evaluated MDA plus other vector control measures. The studies used a wide variety of MDA regimens incorporating different drugs, dosages, timings and numbers of MDA rounds. Many of the studies are now more than 30 years old. Areas of low endemicity ( ≤5 %) Within the first month post‐MDA, a single uncontrolled before‐and‐after study conducted in 1955 on a small Taiwanese island reported a much lower prevalence of parasitaemia following a single course of chloroquine compared to baseline (1 study, very low quality evidence ). This lower parasite prevalence was still present after more than 12 months (one study, very low quality evidence ...

Gold-mining may play an important role in the maintenance of malaria worldwide. Gold-mining, mostly illegal, has significantly expanded in Colombia during the last decade in areas with limited health care and disease prevention. We report a descriptive study that was carried out to determine the malaria prevalence in gold-mining areas of Colombia, using data from the public health surveillance system (National Health Institute) during the period 2010-2013. Gold-mining was more prevalent in the departments of Antioquia, Córdoba, Bolívar, Chocó, Nariño, Cauca, and Valle, which contributed 89.3% (270,753 cases) of the national malaria incidence from 2010-2013 and 31.6% of malaria cases were from mining areas. Mining regions, such as El Bagre, Zaragoza, and Segovia, in Antioquia, Puerto Libertador and Montelíbano, in Córdoba, and Buenaventura, in Valle del Cauca, were the most endemic areas. The annual parasite index (API) correlated with gold production (R2 0.82, p < 0.0001); for every 100 kg of gold produced, the API increased by 0.54 cases per 1,000 inhabitants. Lack of malaria control activities, together with high migration and proliferation of mosquito breeding sites, contribute to malaria in gold-mining regions. Specific control activities must be introduced to control this significant source of malaria in Colombia.
