Malaria is caused by the blood parasite Plasmodium. There are 5 species that infect humans: P. falciparum, P. vivax, P. ovale, P. malariae and in South East Asia only, P. knowlesi.

The parasite is transmitted to humans by the bite of an infected mosquito. The female mosquitoes of the genus Anopheles are the only mosquitoes that can transmit malaria. The malarious areas across the world include:

� Africa, Middle East, Asia, China, South East Asia including Indonesia, East Timor, Papua New *XLQHD��WKH�:HVWHUQ�3DFL¿F�,VODQGV��DQG�&HQWUDO�DQG�6RXWK�$PHULFD�

Advice to parents of students arriving in the NT from malaria endemic areas

What is Malaria? Malaria is a parasitic disease transmitted by Anopheles mosquitoes. There are 4 types of parasites that cause malaria: Plasmodium ovale, P. malariae, P. knowlesi, P. vivax, and P. falciparum. The last 2 are the most common.

Primarily, malaria is an infection of the red blood cells, but other parts of the body may be affected. Malaria caused by P. falciparum DQG� VHYHUH P. knowlesi is life threatening and can cause multiple organ damage, coma and death.

How is it spread? Malaria is spread by Anopheles� PRVTXLWRHV�� 7KH� SDUDVLWH� HQWHUV� WKH� ERG\� LQ� PRVTXLWR� VDOLYD�when a person is bitten by an infected Anopheles PRVTXLWR�� 7KH� SDUDVLWH� ILUVW� LQIHFWV� WKH� OLYHU�where it begins to multiply.

Where is it found? Malaria is found throughout the tropical and subtropical regions of the world. Areas of high transmission are found predominantly in rural areas in South America (e.g. Brazil), south-east Asia (e.g. Thailand, Indonesia and East Timor), Western Pacific (Papua New Guinea, Solomon Islands and Vanuatu) and throughout sub-Saharan Africa.

The last case of locally acquired malaria in the Northern Territory was in 1962 and Australia was GHFODUHG�IUHH�RI�PDODULD�E\�WKH�:RUOG�+HDOWK�2UJDQLVDWLRQ��:+2��LQ�������+RZHYHU��D�QXPEHU�RI�species of Anopheles mosquitoes exist in the NT and the malaria parasite could be re-introduced into local mosquitoes if infected people are bitten. Transmission to mosquitoes could occur anywhere in the Top End, down to latitude of 19 degrees, which is just north of Tennant Creek.

What are the symptoms? Symptoms appear about 9-14 days after a malaria-infected mosquito bite, and coincide with the rupture of the red blood cells. Symptoms are oIWHQ�GHOD\HG�LQ�SHRSOH�ZKR�KDYH�OLYHG�LQ�PDODULRXV�DUHDV�DQG�ZKR�PD\�KDYH�GHYHORSHG�VRPH�LPPXQLW\���

Prolonged untreated malaria infection can also cause the spleen to enlarge (splenomegaly). Splenomegaly can be a problem if your child is playing sport or suffers an abdominal injury, as the spleen can rupture requiring emergency surgery. Splenic rupture can sometimes be fatal.

Why does malaria relapse? Some forms of malaria such as P. vivax and P. ovale exist as dormant forms that remain in the OLYHU�IRU�PRQWKV�RU�\HDUV�EHIRUH�SURGXFLQJ�WKH�GLVHDVH���

Malaria

MalariaCentre for Disease Control

December 2012

What is Malaria?Malaria is a parasitic disease transmitted by Anopheles mosquitoes. There are 5 types of parasites that cause malaria: Plasmodium ovale, P. malariae, P. knowlesi, P. vivax, and P. falciparum. The last 2 are the most common.

Primarily, malaria is an infection of the red blood cells, causing recurring fever of sudden onset. Malaria caused by P. falciparum is life threatening and can cause multiple organ damage, coma and death.

How is it spread?Malaria is spread by female Anopheles mosquitoes. The parasite enters the body in mosquito saliva when a person is bitten by an LQIHFWHG�PRVTXLWR��7KH�SDUDVLWH�¿UVW�LQIHFWV�WKH�liver where it begins to multiply. After some days, the resulting parasites are released into the blood stream to infect the red blood cells, where they continue to multiply, eventually bursting the red blood cells and further infecting others. If they reach high numbers they may cause severe disease or even death. Some of the parasites in the red blood cells develop into the sexual stages (gametocytes). If these stages are ingested when a mosquito bites an infected person, they develop in the gut of the mosquito for 10 –14 days, and then enter the salivary glands, ready for the next bite.

Where is it found?Malaria is found throughout the tropical and subtropical regions of the world. Areas of high transmission are found predominantly in rural areas in South America (e.g. Brazil), south-east Asia (e.g. Thailand, Indonesia and East 7LPRU���:HVWHUQ�3DFL¿F��3DSXD�1HZ�*XLQHD��Solomon Islands and Vanuatu) and throughout sub-Saharan Africa.

The last case of locally acquired malaria in the 1RUWKHUQ�7HUULWRU\�ZDV�LQ������DQG�$XVWUDOLD�was declared free of malaria by the World

The disease could become established anywhere in the Top End, down to a latitude RI����GHJUHHV�ZKLFK�LV�MXVW�QRUWK�RI�7HQQDQW�Creek.

What are the symptoms?6\PSWRPV�DSSHDU�DERXW������GD\V�DIWHU�D�ELWH�from an infected mosquito, and coincide with the rupture of the red blood cells. Symptoms are often delayed in people who have lived in malarious areas and who may have developed some immunity.

Typically malaria produces fever, rigors (shakes), sweating, headache, vomiting and RWKHU�ÀX�OLNH�V\PSWRPV��6RPHWLPHV�WKHUH�is a 2 or 3 day period of reduced symptoms before a recurrence on the third or fourth day. Untreated, infection can progress rapidly and become life threatening. Malaria can kill by destruction of red blood cells (anaemia) and by altering the function of vital organs such as the brain, (cerebral malaria) lungs or kidneys.

Why does malaria relapse?P. vivax and P. ovale exist as dormant forms that remain in the liver for months or years before producing the disease.

With P. falciparum, the disease can reoccur after apparent recovery, due to either inadequate treatment or infection with a drug resistant strain. P. malariae can rarely persist with very low levels of parasite in the peripheral blood for decades.

P. knowlesi produces acute illness but does not cause relapse.

CENTRE FOR DISEASE CONTROL

Malaria

How is it diagnosed?Malaria is diagnosed by a blood test. The blood is examined under a microscope looking for malaria parasites inside the red blood cells. All travellers from malarious areas who become ill or develop a fever should be tested.

What is the treatment?All cases of P. falciparum�PDODULD�LQ�WKH�17�DUH�admitted to hospital because this form of malaria can rapidly become life threatening. Cases of malaria other than P. falciparum can sometimes be treated at home if the house is adequately screened and if the patient agrees to stay indoors between dusk and dawn. This is to avoid any risk of transmission of the parasite to the local Anopheles mosquitoes.

Treatment must be given in consultation with specialist physicians.

Before travelling overseasCheck whether the countries to which you are travelling are affected by malaria by contacting your *3��7UDYHO�+HDOWK�&OLQLF�RU�UHIHUULQJ�WR�WKH�LQWHUQHW�

WHO International Travel and Health website:http://www.who.int/ith/en/

Or the Centers for Disease Control and Prevention:http://wwwnc.cdc.gov/travel/

If you are travelling to an affected country you will often need preventative medication. Contact \RXU�*3�RU�7UDYHO�&OLQLF�WR�RUJDQLVH�DQWL�PDODULDO�medication for your trip. Some medication must be started 1 week prior to entry to the affected area.

How to protect yourself from mosquito bitesWhile in affected areas there are measures which should be taken to reduce the risk of mosquito bites.

�� Avoid being outdoors between dusk and dawn to avoid mosquito bites, particularly in poorly lit areas, rural areas, or the outskirts of large towns.

�� If accommodation is not well screened, sleep inside mosquito netting. Use insecticide treated bed nets and clothing in high risk areas.

�� Avoid scents on the body, e.g. perfume, deodorants, and sweat, since these can attract mosquitoes.

�� Use protective clothing in outdoor situations including covering feet, legs and arms. Loose, light coloured clothing is best.

�� Use personal repellents containing DEET or picaridin on areas of exposed skin in combination with protective clothing.

�� Use electric insecticide devices using repellent treated pads in indoor or enclosed areas.

�� Use mosquito coils, or candle heated or gas operated devices using insecticide treated pads for patio and veranda or relatively sheltered or low wind outdoor situations.

For more information on protection measures see Personal protection from mosquitoes.

If you return from a malarious area and develop symptomsIf you develop symptoms of malaria within 2 years of YLVLWLQJ�D�PDODULRXV�DUHD�FRQWDFW�\RXU�*3�RU�KRVSLWDO�emergency department immediately for an urgent medical assessment. Remember to inform the PHGLFDO�RI¿FHU�RI�ZKHUH�\RX�KDYH�WUDYHOOHG�DV�WKLV�will help determine your risk of malaria and the type of treatment required.

If you have malaria, the people you have travelled with (particularly to high risk areas such as Africa, 31*��(DVW�7LPRU�DQG�SDUWV�RI�,QGRQHVLD�LQFOXGLQJ�Flores, Lombok and surrounding islands) should also be tested.

Apakah Malaria?Malaria adalah penyakit yang disebabkan oleh parasit yand ditularkan oleh nyamuk Anopheles. Ada 5 jenis parasit yang dapat menyebabkan malaria: Plasmodium ovale, P. malariae, P. vivax, P.knowlesi dan P. falciparum. Dua jenis terakhir adalah yang paling sering ditemukan.

Pada dasarnya, malaria adalah infeksi pada sel-sel darah merah, yang menyebabkan demam berulang dengan tiba-tiba. Malaria yang disebabkan oleh P. falciparum sangat berbahaya dan dapat menyebabkan kerusakan berbagai organ tubuh, koma dan kematian.

Bagaimana malaria menyebar?Malaria disebarkan oleh nyamuk Anopheles betina. Parasit masuk ke tubuh melalui ludah nyamuk pada saat seseorang digigit oleh nyamuk yang terinfeksi. Parasit ini mula-mula PHQ\HEDENDQ�UDGDQJ�SDGD�OLYHU�GLPDQD�LD�berbiak. Setelah beberapa hari, parasit-parasit yang terbiak dilepas ke saluran darah untuk menjangkiti sel-sel darah merah, dimana mereka terus berbiak, sampai sel-sel darah merah menjadi pecah dan mengakibatkan infeksi pada sel-sel lainnya. Jika jumlahnya menjadi sangat besar, hal ini dapat menimbulkan sakit parah atau bahkan kematian. Sebagian dari parasit dalam sel-sel darah merah berkembang memasuki tahap jantan dan betina (gametosit). Jika pada tahap ini seekor nyamuk mengigit orang yang terinfeksi, parasit akan berkembang dalam perut nyamuk selama 10-14 hari, lalu masuk ke kelenjar ludah, siap untuk dijangkitkan pada saat nyamuk menggigit seseorang.

Dimana penyakit ini menyebar?Malaria ditemukan diseluruh wilayah tropis dan subtropis di dunia. Daerah-daerah dimana terjadi banyak penularan adalah wilayah perkampungan di Amerika Selatan (misalnya Brazil), Asia Tenggara (misalnya Thailand, ,QGRQHVLD�GDQ�7LPRU�7LPXU���3DVL¿N�%DUDW�(Papua Nugini, Kepulauan Solomon dan Vanuatu) serta sub-Sahara di Afrika.

Di Northern Territory, kasus malaria yang terjangkit secara lokal terakhir terjadi pada tahun 1962 dan Australia dinyatakan bebas dari Malaria oleh World Health Organisation (WHO) pada tahun 1981. Namun, beberapa spesies nyamuk Anopheles masih ada di NT dan parasit malaria dapat menjangkiti nyamuk setempat bila ada pendatang yang terinfeksi dari luar negeri digigit oleh nyamuk setempat. Penyakit ini dapat berjangkit di wilayah utara NT, sampai dengan lintang 19 derajat, sedikit di utara Tennant Creek.

Apakah gejala-gejalanya?Gejala-gejala muncul sekitar 9-14 hari setelah digigit oleh nyamuk yang terinfeksi, dan bersamaan dengan pecahnya sel-sel pembuluh darah merah. Pada orang yang tinggal di daerah yang banyak terjangkit malaria, gejala-gejalanya mungkin muncul lebih lambat karena orang tersebut mungkin memiliki sedikit kekebalan.

Pada umumnya malaria mengakibatkan demam, menggigil, keringatan, sakit kepala, muntah-PXQWDK�GDQ�JHMDOD�VHUXSD�ÀX�ODLQQ\D��.DGDQJ�kadang gejala-gejala ini berkurang selama 2-3 hari namun muncul kembali pada hari ketiga atau keempat. Tanpa pengobatan, infeksi dapat berkembang dengan cepat dan membahayakan jiwa. Malaria dapat mengakibatkan kematian melalui penghancuran sel-sel darah merah (anaemia) dan melalui perubahan pada fungsi organ tubuh yang penting seperti otak (cerebral malaria), paru-paru dan ginjal.

Mengapa malaria dapat kambuh?P. vivax dan P. ovale tinggal dalam bentuk WLGDN�DNWLI�SDGD�OLYHU�VHODPD�EHUEXODQ�EXODQ�atau bertahun-tahun sebelum menyebabkan munculnya penyakit. Pada P. falciparum, penyakit dapat kambuh kembali setelah seseorang terlihat sembuh, karena pengobatan yang kurang memadai atau orang tersebut tertular jenis yang kebal terhadap obat. P. malariae jarang dapat bertahan dengan tingkat parasit rendah pada darah selama puluhan tahun.

APPENDIX 9. Malaria factsheet (Indonesian)Bagaimana di-diagnosa ?Malaria di-diagnosa melalui tes darah. Darah diperiksa dibawah mikroskop untuk dilihat apakah terdapat parasit malaria dalam sel-sel darah merah. Semua orang yang bepergian ke daerah dimana malaria berjangkit dan jatuh sakit atau mengalami demam harus diperiksa.

Bagaimana mengobatinya?Seluruh kasus malaria P. falciparum di NT dikirim ke rumah sakit karena malaria jenis ini dapat membahayakan jiwa dalam waktu singkat. Kasus-kasus diluar P. falciparum kadangkala dapat diobati di rumah jika rumah tersebut dilindungi kawat nyamuk dan jika pasien setuju untuk tinggal dalam rumah dari senja hingga fajar. Hal ini untuk menghindari resiko penularan parasit ke nyamuk Anopheles setempat.

Pengobatan harus dilakukan dengan berkonsultasi pada dokter spesialis. Sebelum bepergian ke luar negri, periksalah apakah negara-negara yang akan Anda kunjungi terjangkit malaria dengan menghubungi dokter Anda, Travel Health Clinic atau melalui internet:

Situs web WHO International Travel and HealthKWWS���ZZZ�ZKR�LQW�LWK�LQGH[�KWPOatau Centers for Disease Control and Prevention (Pusat Pengendalian dan Pencegahan Penyakit) KWWS���ZZZ�FGF�JRY�WUDYHO�GLVHDVHV�KWP�PDODULD

Jika Anda akan bepergian ke negara yang terjangkit, pada umumnya Anda memerlukan obat pencegahan. Hubungi dokter Anda atau Travel Clinic untuk memperoleh obat anti-malaria bagi perjalanan Anda. Obat-obat tertentu perlu diminum 1 minggu sebelum memasuki wilayah yang terjangkit.

Bagaimana melindungi diri Anda dari gigitan nyamuk Selama di daerah yang terjangkit, ada hal-hal yang dapat dilakukan untuk mengurangi resiko digigit nyamuk.

� hindari berada di luar bangunan antara senja dan fajar, terutama di daerah yang kurang penerangannya, daerah perkampungan, atau pinggiran kota besar

� tutupi badan Anda (terutama lengan, tungkai kaki dan telapak kaki) antara senja dan fajar

pakaian yang longgar dan berwarna terang adalah yang terbaik

� gunakan penolak serangga pada kulit yang tidak terlindungi pada jam-jam yang beresiko tinggi; pilih penolak yang mengandung DEET atau picaradin

� hindari bau-bauan pada tubuh, misalnya parfum, deodoran, dan keringat, karena dapat menarik nyamuk

� jika akomodasi tidak terlindung dengan baik, tidur dengan menggunakan kelambu. Gunakan kelambu dan pakaian yang telah disemprot penolak serangga di daerah beresiko tinggi

� gunakan obat nyamuk bakar atau pembasmi serangga dalam bentuk uap di ruang tertutup

Jika Anda kembali dari daerah yang terjangkit malaria dan menunjukkan gejala-gejala malariaJika Anda menunjukkan gejala-gejala malaria dalam 2 tahun setelah mengunjungi daerah yang terjangkit malaria, hubungi dokter atau bagian gawat darurat rumah sakit dengan segera untuk pemeriksaan medis. Jangan lupa memberi tahu petugas kesehatan tempat-tempat yang Anda kunjungi karena ini akan membantu menentukan tingkat resiko Anda terkena malaria dan jenis perawatan yang diperlukan.

Jika Anda terkena malaria, orang-orang yang bepergian bersama Anda (terutama ke daerah beresiko tinggi seperti Afrika, PNG, Timor Timur dan bagian dari Indonesia termasuk Flores, Lombok dan kepulauan sekitarnya) perlu juga diperiksa.
