La Malaria es una enfermedad causada por un parásito que se transmite a los humanos a través de la picadura de mosquito hembra Anophele. Reportando la WHO en el 2019, 229 millones de casos y 409.000 muertes por la enfermedad en 87 paises del mundo, Existen seis especies de este párasito: Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale wallickeri, Plasmodium ovale curtisi, Plasmodium malariae y Plasmodium knowlesi. Siendo la especie P. falciparum la causante de mayor morbilidad, con tasa entre 10 y 50% de mortalidad por malaria complicada. Alrededor de 108 países han declarado la malaria como enfermedad endémica, pudiendo padecer la enfermedad en cualquier época del año. Sin embargo, en el caso de América Latina hoy en día se vive un estancamiento de la enfermedad, reportándose en países menos de 100 casos autóctonos entre el 2000 y 2019, con algunas excepciones. Esta situación de vulnerabilidad de países como Brasil, Colombia, la frontera Perú-Ecuador, Venezuela, se incrementan ante la presencia activa de la pandemia producto del Covid -19 aunado a restricciones económicas, incremento de la actividad minera, o políticas públicas que ponen en riesgo la sostenibilidad del programa de control de la enfermedad. Para el 2021 la OMS corrobora que existen 87 países con malaria a nivel mundial, de los cuales 24 de ellos habían interrumpido su transmisión autóctona por 3 años. Realidad que consolidad la propuesta tras la experiencia adquirida, que cualquiera que sea la situación epidemiológica de entrada, el trabajo hacia la erradicación de la malaria debe entenderse y atenderse como un proceso continuo donde los propios Estados deben desde su realidad y estrategias propias se articulen con el Plan Estratégico Técnico Mundial Contra la Malaria 2016-2030 propuesto por la OMS.

ABSTRACT Malaria is considered one of the most important scourges that humanity has faced during its history, being responsible every year for numerous deaths worldwide. The disease is caused by protozoan parasites, among which two species are responsible of the majority of the burden, Plasmodium falciparum and Plasmodium vivax. For these two parasite species, the questions of their origin (how and when they appeared in humans), of their spread throughout the world, as well as how they have adapted to humans have long been of interest to the scientific community. In this paper we review the existing body of knowledge, including current research dealing with these questions, focusing particularly on genetic and genomic analyses of these parasites and comparison with related Plasmodium species infecting other species of host (such as non-human primates).

Malaria contagious by mosquito Anopheles Betina bringing protozoa parasite in its body (Plasmodium). Plasmodium there are four specieses that is Plasmodium vivax, Plasmodium ovale, Plasmodium malariae and Plasmodium falciparum, but often becomes pathogen that is Plasmodium vivax and Plasmodium falciparum. As for intention of this research is to identify Plasmodium which is dominant at female Anopheles mosquito (Anopheles spp.) and knows distribution pattern of female Anopheles mosquito (Anopheles spp.) in some places in Districts Manokwari Barat. Based on research result done to four locations that is area Amban, Wosi, Sanggeng and Kota is found [by] 1024 mosquito tails. From the amounts only 115 mosquito tails was mosquito Anopheles Betina while the other is mosquito Anopheles male, mosquito Culex and Aedes. Mosquito Anopheles Betina found consisted of 4 species that is Anopheles bancrofti, Anopheles kochi, Anopheles farauti and Anopheles koliensis. Mosquito Anopheles Betina which is dissected, obtained 2 the Plasmodium species in mosquito spit gland is Plasmodium vivax and Plasmodium falciparum, and from calculation by index dominant can be told that both types of this very dominant Plasmodium in Districts Manokwari Barat because its the dominant index > 5%.

ABSTRACTAcute kidney injury (AKI) is a frequent presentation in Plasmodium vivax (P. vivax) associated severe malaria. However, tissue presence of P. vivax parasites in the kidney has never been demonstrated. In the present study, we show that renal biopsies from malaria associated AKI patients harbor the human malaria parasite P. vivax and, in several cases, the zoonotic monkey malaria parasite P. knowlesi in addition to P. vivax. Presence of microvascular injury in a majority of the malaria associated AKI cases suggests vascular involvement of P. vivax and P. knowlesi. This study implicates Plasmodium species as a possible pathogenic mechanism for AKI, and suggests host renal tissue interaction of P. vivax and P. knowlesi.

Abstrak Malaria adalah salah satu penyakit yang disebabkan oleh infeksi parasit yang dapat menyebabkankematian pada manusia. Penyakit infeksi ini disebabkan oleh parasit Plasmodium yang hidup dan berkembangbiak dalam sel darah merah manusia dan ditularkan melalui gigitan nyamuk Anopheles. Ada lima spesiesPlasmodium yang menyerang manusia yaitu : Plasmodium vivax, Plasmodium falciparum, Plasmodium malariae,Plasmodium ovale dan Plasmodium knowlesi. Penelitian ini merupakan jenis penelitian deskriptif denganrancangan penelitian crossectional atau potong lintang. penelitian ini dilakukan pemeriksaan skrining denganmaksud untuk melihat positif atau negatif parasit malaria di dalam sampel darah mengunakan mikroskop.Skrining malaria merupakan suatu usaha untuk mencari dan menemukan penderita penyakit malaria yangtampak gejala klinis melalui suatu tes atau pemeriksaan, yang secara singkat dan sederhana sehingga dapatmemisahkan mereka yang sehat dari mereka yang kemungkinan besar menderita penyakit malaria, yangselanjutnya diproses melalui diagnosis dan pengobatan. Penelitian ini dilakukan di laboratorium puskesmas BumiWonorejo kabupaten Nabire provinsi Papua tahun 2018. Sampel dalam penelitian ini adalah sebanyak 30 orang. Yaitu orang dengan gejala klinis seperti demam periodik, nyeri pada persendian, mual dan tinggal di wilayah kerjapuskesmas Bumi Wonorejo Nabire-Papua serta subjek bersedia di ambil sampel darah. Berdasarkan gambaran hasil pemeriksaan mikroskopis di Puskesmas Bumi Wonorejo Nabire-Papua tahun 2018 pada sediaan darahsubjek penelitian di peroleh positif malaria sebanyak 19 orang ( 63,3%) dan negatif malaria yaitu 11 0rang(36,3%). Sehingga dapat disimpulkan bahwa kasus positif malaria di wilayah kerja Puskesmas Bumi WonorejoNabirePapuatahun2018masihtinggi. Katakunci:skrining,mikroskopis,malari
