In answer to your three questions, Malaria is caused by protozoan parasites of the genus Plasmodium. Four species of Plasmodium can produce the disease in its various forms: Plasmodium falciparum Plasmodium vivax. Plasmodium ovale. Plasmodium malaria. P. falciparum is the most widespread and dangerous of the four: untreated it can lead to fatal cerebral malaria. Malaria has been known since time immemorial, but it was centuries before the true causes were understood. Previously, it was thought that "miasma" (bad air or gas from swamps - "mal air ia") caused the disease. Surprisingly in view of this, some ancient treatments were remarkably effective. An infusion of qinghao (Artemesia annua ) has been used for at least the last 2000 years in China, its active ingredient (artemisinin) having only recently been scientifically identified. The antifebrile properties of the bitter bark of (Cinchona ledgeriana ) were known in Peru before the 15th century. Quinine, the active ingredient of this potion was first isolated in 1820 by the pharmacists. Malaria parasites are transmitted from one person to another by the female anopheline mosquito. The males do not transmit the disease as they feed only on plant juices. There are about 380 species of anopheline mosquito, but only 60 or so are able to transmit the parasite. Like all other mosquitos, the anophelines breed in water, each species having its preferred breeding grounds, feeding patterns and resting place. Their sensitivity to insecticides is also highly variable. Plasmodium develops in the gut of the mosquito and is passed on in the saliva of an infected insect each time it takes a new blood meal. The parasites are then carried by the blood in the victim's liver where they invade the cells and multiply: Malaria is complex but it is a curable and preventable disease.
I add a link which discusses this subject.

No, not necessarily. Malaria can be treated. If the right drugs are used, people who have malaria can be cured and all the malaria parasites can be eliminated. However, the disease can persist if it is left untreated or if it is treated with the wrong drug. Some drugs are ineffective because the parasite is resistant to them. Some patients may be treated with the right drug, but at the wrong dose or for too short a period of time. Two types (species) of parasites, Plasmodium vivax and P. ovale, have dormant liver stages that can remain silent for years. Left untreated, these liver stages may reactivate and cause malaria attacks ("relapses") after months or years without symptoms. Patients diagnosed with P. vivax or P. ovale are often given a second drug to help prevent these relapses. Another type (species), P. malariae, if left untreated, has been known to persist in the blood of some persons for several decades. But in general, if you are correctly treated for malaria, the parasites are eliminated and you are no longer infected with malaria. Malaria Drugs

Yes.
In most cases the person is cured in a sense, does not feel the effect of Malaria infection. The person can and in most case will become carrier of Malaria.
Here is my article on Malaria.

You Need a Malaria infected or had infection creacher and a female mosquitoes (female need blood meal for reproduction).
Then if mosquitoes bites the person (animal or bird) who had malaria, that creacher will make mosquito contaminated, it will carry the malaria and transfer it to any creacher on subsequent bits.
Qualex and Anopheles mosquitoes are the major suspects(carriers).
Even without or any further exposure a person(carrier) can have re-occurrence of Malaria if the immune system is low due to some other reason or sickness.

Ah, a exact mentioned case. Malaria lives in crimson blood cells (RBCs). inspite of the easy actuality that, persons who carry the sickle cellular trait - are heterozygous for it - have 50% malformed RBCs. which potential 0.5 as plenty malaria (possibly the larvae, doubtful) infect them, allowing their bodies to mount an attack on the malaria. Sickle cellular is so named using actuality the RBCs shaped from this allele appear as if a sickle - curved, hollow, as unfavourable to around.
