A small outbreak of malaria was reported at Linden, the major mining town of bauxite and alumina, and situated 105 km up the Demerara River. Mass blood and fever case surveys were undertaken, coupled with subsequent passive case detection at the complex's hospital. Twelve vivax malaria cases were found; seven of these seem to have been infected indigenously. Corresponding surveys on the anopheline vectors showed for the first time since 1948 the presence of An. darlingi Root, 1926 in the outbreak areas of the upper Demerara River. Further, another known vector in Guyana, An. aquasalis Curry, 1932 was also found biting. The presence of An. intermedius Peryassu, 1908 was confirmed and An. bellator Dyar & Knab, 1906 was reported from Guyana for the first time. An. braziliensis Chagas, 1907 was also sampled. The presence of known vectors of malaria in Guyana i.e. An. darlingi and An. aquasalis and vivax malaria parasites up the Demerara River emphasize the possible reinvasion of the densely populated coastland with malaria.
据报道，在铝土矿和氧化铝的主要矿业城镇林登发生了小规模疟疾疫情，该城镇位于德梅拉拉河上游105公里处。开展了大规模血液和发热病例调查，并随后在该综合设施的医院进行了被动病例检测。发现了12例间日疟病例；其中7例似乎是本地感染。对按蚊媒介进行的相应调查自1948年以来首次显示，在德梅拉拉河上游的疫情地区存在1926年的达林按蚊。此外，在圭亚那另一种已知的媒介——1932年的库里嗜水按蚊也被发现正在叮咬。1908年的中间按蚊的存在得到了证实，1906年的贝拉托按蚊首次在圭亚那被报道。1907年的巴西按蚊也被采样。在德梅拉拉河上游存在圭亚那已知的疟疾媒介，即达林按蚊和库里嗜水按蚊以及间日疟原虫，这凸显了疟疾可能再次侵袭人口密集的沿海地区。
