Malaria is a sporozoan[1] parasite[2] that attacks red bloods cells.
The parasite uses red blood cells to reproduce, in doing so - the red blood cells are destroyed. Malaria is transmitted to humans through the female anopheles mosquito. Pregnant female mosquitoes require human blood for nourishment. The malaria parasite is in the saliva of the mosquito that is injected into the human when the mosquito attempts to draw blood from the human. If a mosquito does NOT have malaria, but the human host DOES - then the mosquito will contract[3] the malaria parasite from the human's blood. The mosquito will go on to infect its next human host/meal with malaria. Red blood cells are important to humans because they convey oxygen throughout the human body. If red blood cells stop functioning, the body will stop functioning.

Lost health Anemia[4], fever/chills, vomiting, headaches, diarrhea, retardation (fetal + child dev.) False treatment of malaria may cause people to overlook other health-threatening illnesses Lost money False treatment and/or over treatment of illness Transport, medical costs, etc.. Can't go to work, can't get new money Lost time Can't go to work Can't go to school (lost education) Can't take care of family Lost lives Can't socialize Can't develop/grow properly Death

Pregnant women Children Everyone
Increased body temperature increases the possibility of mosquito attraction. Pregnant women also exhale more, thereby producing greater quantities of carbon dioxide - a compound that attracts mosquitoes. Pregnant women sweat more; the resulting odors attract mosquitoes. Children Life-style behavior: playing and working outside in inappropriate environment without proper protection Weaker (less immune[5]) health system susceptible to effects of malaria (severe anemia, developmental retardation, etc..) Everyone Pregnant women attract mosquitoes bc they exhale more and produce more carbon dioxide. also because they tend to sweat more. didn't find anything concrete on the hormone factor. Source:wedmd -Amparo (slides corrected, thanks Amparo!) There is no vaccine[6] for malaria. No one's immunity level is sufficiently high to fully protect against malaria. Mosquitoes and malaria adapt to their environment very fast - they evolve very quickly. All humans are potential blood meals for mosquitoes.

700,000 + deaths from malaria per year (current).
90% of deaths from malaria affect children under age 5. Sub-Saharan Africa accounts for most of the deaths from malaria. 9% of maternal deaths are attributed to malaria. (Ghana DHS 2008) 1 in 15 children under age 5 in Ghana die of malaria. (Ghana DHS 2008) Various research and development organizations are working to fight malaria through the following means: Research (drugs, vector control[7], maintenance/sustainability, vaccine) Indoor Residual Spraying (IRS) Insecticide Treated Nets (ITNs) / Long-Lasting Insecticidal Nets (LLINs) Intermittent Preventive Treatment during Pregnancy (IPTp) Intermittent Preventive Treatment for Children (IPTc) yes, fact is correct. of all malaria deaths, 90% are children. source: -Amparo (don't know how to add notes on here)

Universal coverage (bednets) Insecticidal spraying (spraying houses)
Millennium Development Goal for malaria continues to push various efforts/organizations in the following: Universal coverage (bednets) Insecticidal spraying (spraying houses) Increased/improved public education on malaria Prevention, treatment, etc.. Increased/improved quality/availability of treatment Intermittent Preventive Treatment during Pregnancy (IPTp) Intermittent Preventive Treatment for Children (IPTc) Malaria vaccine + innovations in antimalaria drugs
9
Sleep under an insecticide treated net EVERY NIGHT.
Wear appropriate clothing that covers skin. Also wear socks (foot odors attracts mosquitoes!) Use insect repellent while farming/working outside and at night. Intermittent Preventive Treatment for Children (IPTc) - seek regular dosages of antimalarials during peak malaria transmission season.

If you experience the following combined symptoms -
you may need to get officially tested for malaria. If you experience the following combined symptoms - you may need to get officially tested for malaria. Headaches Vomiting / Nausea Fever / Chills Diarrhea Typically, malaria infections are characterized by a cyclic[9] pattern in these symptoms.
13
Pharmacy + Home Health clinic Hospital
Some pharmacies may carry rapid diagnostic tests (RDTs) for malaria detection; these tests can be administered at home to qualitatively verify[8] the presence of the parasite. Proper RDT training is necessary for effective results. Make sure to either have a trained person administer the test, or have a capable person read/understand the test's instructions before administering the test. Health clinic Most clinics will be able to administer diagnostic tests for malaria detection/verification. Some clinics, depending on staff capacity may be ale to perform microscopy in diagnosing the extent/degree of malaria infection. Hospital Most major hospitals will be able to administer RDTs and perform microscopy to gauge the severity of malarial infection.
14
Rapid Diagnostic Tests (RDTs)
Uses antibodies/antigens to test for the presence of malaria parasite in patient's blood. Blood usually extracted from finger tip. Produces qualitative results ONLY. Very quick test,10-15 minutes to obtain results once blood and buffering agent are combined on dipstick. Requires minimal training and RDTs are very inexpensive and readily available. Microscopy Malarial microscopy entails the actual detection and tallying of affected blood cells within a given blood sample (usually a thin/thick blood smear). Blood usually extracted from finger tip. Produces quantitative results. Requires intensive training and expensive materials: Microscope, slides, stains, electricity/light source. Microscopy is not readily available in most parts of Africa.
15
When testing verifies the presence of malaria, treatment must promptly be administered.
If test is inconclusive or negative, and symptoms are severe or persistent, it is necessary to go to a clinic/hospital. IF symptoms that are attributable to malaria are SEVERE, and testing isn't easily/readily available, but treatment IS available - it is best to go ahead and immediately take the standard treatment regiment for malaria. BUT, continue to seek proper diagnosis of ailment in order to reorient treatment efforts. Pregnant women: seek intermittent preventive treatment (IPTp) First dosage: 16 weeks gestation Second dosage: 1 month after first dosage Third dosage: 1 month after second dosage Children Under 5: seek intermittent preventive treatment (IPTc) Up to four (4) doses during heavy transmission seasons.
16
Seek anti-malaria drugs (ACTs[10]) from pharmacy.
Read instructions for the proper use of the drug, AND have pharmacist verify your understanding. Stick to the regiment/program that the drug's instructions recommends. DO NOT stop taking it unless: You have fully depleted the doses for the treatment. You have adverse effects to the drug. IPTp and IPTc can be administered at most local, district, and regional clinics. Most clinics should have the ability to administer and monitor conventional treatment regiments. Severe malaria cases might have to be referred to more equipped/qualified facilities however. Hospitals have the ability to treat uncomplicated and complicated malaria with either conventional antimalarial medication or injections. IPTp and IPTc should be available to pregnant women and children at most hospitals.
17
Mono-Therapies: most commonly used drugs in the past; the malaria parasite has acquired a substantial immunity (resistance) to these drugs - prompting the need for combination therapies. Chloroquine Amodiaquine Sulfadoxine–Pyrimethamine (SP): now primarily used as a preventative measure for pregnant women and children. Combination Therapies: Artemisinin Combination Therapy (ACT) artemether/lumefantrine (AL) : secondary antimalarial drug in Ghana artesunate (AS) + amodiaquine (AQ): primary antimalarial drug in Ghana artesunate (AS) + mefloquine (MQ) artesunate (AS) + sulfadoxine/pyrimethamine (SP)

Sporozoan (i) : Any of numerous parasitic protozoans of the class Sporozoa, most of which reproduce sexually and asexually in alternate generations by means of spores. They are frequently transmitted by bloodsucking insects to different hosts, where they cause many serious diseases, such as malaria and coccidiosis. Parasite (i) : An organism that grows, feeds, and is sheltered on or in a different organism while contributing nothing to the survival of its host. Contract (i) : To acquire or incur. (To get.) Anemia (i) : A deficiency in the oxygen-carrying component of the blood, as in the amount of hemoglobin or the number or volume of red blood cells. Iron deficiency, often caused by inadequate dietary consumption of iron, and blood loss are common causes of anemia. Immune (i) : Protected against a specific disease by inoculation or as the result of innate or acquired resistance. Vaccine (i) : A preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure that upon administration stimulates antibody production or cellular immunity against the pathogen but is incapable of causing severe infection. Vector Control (ii) : Controlling the means/route of transmission (i.e. mosquito control in the case of the malaria parasite). Qualitatively verify (ii) : Determine only the presence of the malaria parasite, NOT the extent/degree/severity of infection (quantitative). Cyclic (i) : Recurring or moving in cycles. ACT (iii) : Artemisinin Combination Therapy Artemisinin (iii) : A class of drugs used for the treatment (not prevention) of malaria usually as a part of a combination therapy, derived from the sweet wormwood or Qinghao plant (Artemisia annua).
