What is the difference between artemether and artesunate?
Artesunate is the water soluble sodium hemisuccinyl ester, whilst artemether is the lipid soluble methyl ether of dihydroartemisinin. Both artesunate and artemether are metabolized in vivo to the highly active antimalarial metabolite, dihydroartemisinin (DHA) [5, 6].

What is the best treatment for P. falciparum?
P. falciparum infections acquired in areas with chloroquine resistance, four treatment options are available. These include artemether-lumefantrine (Coartem™), which is the preferred option if readily available, and atovaquone-proguanil (Malarone™). These are fixed-dose combination therapies that can be used for pediatric patients ≥5 kg. Quinine sulfate plus doxycycline, tetracycline, or clindamycin is the next treatment option. For the quinine sulfate combination options, quinine sulfate plus either doxycycline or tetracycline is generally preferred to quinine sulfate plus clindamycin because there are more data on the efficacy of quinine plus doxycycline or tetracycline. Quinine should be given for 3 days, except for infections acquired in Southeast Asia where 7 days of treatment is required. The fourth option, mefloquine, is associated with rare but potentially severe neuropsychiatric reactions when used at treatment dose. We recommend this fourth option only when the other options cannot be used. In addition, mefloquine is not recommended for infections acquired in certain parts of Southeast Asia due to drug resistance. Options for treatment of pregnant women is presented in the “Alternatives for Pregnant Women” section below. Due to the risk of progression to severe disease, uncomplicated malaria treatment should be initiated as soon as possible with the regimen that is most readily available. In addition, clinicians should hospitalize patients with P. falciparum infection to monitor clinical response and check parasitemia every 12–24 hours. Then, clinicians can consider outpatient completion of treatment for patients with improved clinical symptoms and decreasing parasitemia.

What is malaria elimination?
Malaria elimination is defined as the interruption of local transmission of a specified malaria parasite species in a defined geographical area as a result of deliberate activities. Continued measures are required to prevent re-establishment of transmission. Malaria eradication is defined as the permanent reduction to zero of the worldwide incidence of malaria infection caused by human malaria parasites as a result of deliberate activities. Interventions are no longer required once eradication has been achieved.

How to prevent malaria?
However, there is insufficient evidence that mosquito repellents can prevent malaria infection. Insecticide-treated mosquito nets (ITNs) and indoor residual spraying (IRS) are effective, have been commonly used to prevent malaria, and their use has contributed significantly to the decrease in malaria in the 21st century. ITNs and IRS may not be sufficient to completely eliminate the disease as these interventions depend on how many people use nets, how many gaps in insecticide there are (low coverage areas), if people are not protected when outside of the home, and an increase in mosquitoes that are resistant to insecticides. Modifications to people's houses to prevent mosquito exposure may be an important long term prevention measure.
What is the cause of malaria?
Malaria is caused by single-celled microorganisms of the Plasmodium group. The disease is most commonly spread by an infected female Anopheles mosquito.
