Are yellow fever and malaria the same thing?
336574
No, but they are both spread by mosquitoes. Yellow fever is spread by Aedes mosquitoes, but malaria is spread by Anopheles mosquitoes. Yellow fever is caused by a member of the Flavivirus family. Malaria is caused by parasites: Plasmodium falciparum, P. malariae, P. ovale\n\nYellow fever is vaccine-preventable. Malaria does not have a vaccine, but there are some prophylactic drugs and disease treatments.

Malaria (literally meaning --bad air disease, so named because before the discovery of the cause it was thought tobe caused by air pollution)is caused by Malarial parasites of four types 1)Plasmodium vivax 2)Plasmodium falciparum 3)Plasmodium ovale 4)Plasmodiun malariae.Malaria is spread by female anopheles mosquito.

wow, that's all so wrong in so many ways.  staphylococcus is a genus of bacteria.  not a virus at all. and speaking of not a virus at all, malaria isn't caused by viruses or bacteria, but by parasites.\n\nany doctor who said that is...wow... really, really awful.

yes if there is yellow fever then why not blue fever

If a disease has an insect or animal vector, the spread of the disease will be controlled by the spread of the vector.  For example, you'd be hard pressed to find malaria in Switzerland, because the climate does not support the type of mosquitoes that carry malaria.  Similarly, we have watched the spread of bird flu from China to the rest of the world along the paths of migrating wildfowl.  Dengue most likely came to the US with mosquitoes inside tires brought here from Asia for recycling.\n\nIf a disease is carried only by humans, then it is spread as humans move.  Even some insect borne diseases are affected by humans.  For example The Black Death (bubonic plague) spread out into Europe from seaports.  It was carried in fleas, on rats, in the holds of ships.  Cholera spread around the world as people with the disease deposited their wastes in places with bad sewer systems.\n\nAIDS is actually two different but very similar diseases which arose in two parts of Africa.  It spread throughout Africa along major routes of human migration.  It is still less common north of the Sahara Desert than south of it.  \n\nAIDS is not really limited be geography because it involves human behaviors of choice.  If I sneeze into my hand and then open a door and you come by a half hour later and touch that door knob and then touch the mucous membranes of your face without washing in between, you will most likely get my cold or flu or whatever.  If I have AIDS, however, you won't catch it.  AIDS is spread by sexual contact and activities where blood moves from person to person, such as sharing needles used for injecting drugs and receiving blood donations (although blood is screened now).  This is why Ebola is still in Africa and AIDS is not.\n\nThe spread of AIDS throughout Africa has more to do with political (war) and socioeconomic conditions that encouraged the mass migrations of people, primarily out of the jungles into the cities.  In addition to bringing diseases into enormous new populations, which would have even encouraged easily transmissable diseases like measles, the behaviors encouraged by having large populations of males without access to women of their own tribes to marry and large populations of women with no way to support themselves besides prostitution really kicked the disease in the butt.\n\nIt's also no accident that in the West, the disease was traced back to Gaetan Dugas, an Air Canada flight attendant.  Although some now dispute this, it is true that Dugas was sexually promiscuous even after he knew he had AIDS and in fact was displaying the tumors of Kaposi's sarcoma.  If anyone could help AIDS cross geographic boundaries, it would be someone who traveled a lot.

Malaria is one of the most common infectious diseases in the world, and severe respiratory complications have been described mainly in association with Plasmodium falciparum. We describe a case of acute respiratory distress syndrome complicating infection with P. vivax in the setting of relatively low parasitemia in a 47-yr-old woman after a brief trip to Papua New Guinea. A review of the literature shows that pulmonary complications of P. vivax are rare but occur more frequently than generally acknowledged. Pathogenic mechanisms of these complications are discussed.

HIV affects the circulatory system as well as every other system in your body.  \n\nDengue Hemorrhagic Fever Infections produce a spectrum of clinical illness ranging from a nonspecific viral syndrome to severe and fatal hemorrhagic disease.\n\n\nEbola haemorrhagic fever (EHF) is one of the most virulent viral diseases known to humankind, causing death in 50-90% of all clinically ill cases. Several different species of Ebola virus have been identified.

prettylade has an excellent answer here. \n\nI wanted to add that malaria is an infectious disease though and if you or someone you know has this,you are required to let your doctor know prior to examination. \n\nPrecautions can then be taken to prevent others from contracting the disease.\n\nYou are putting many other lives at risk of contracting the disease if you leave it untreated or if you don't make others aware that you know you have malaria.\n\nI sincerely hope that you are just asking this question out of curiosity and that you are healthy and well.

Malaria is derived from mala aria (Medieval Italian for "bad air") and formerly called ague or marsh fever in English, is an infectious disease which causes about 350-500 million infections with humans and approximately 1.3 - 3 million deaths annually, mainly in the tropics. Sub-Saharan Africa accounts for 85-90% of these fatalities. The death rate is expected to double in the next 20 years. The exact statistics are unknown because many cases occur in rural areas where people do not have access to hospitals and/or the means to afford health care. Consequently, many cases are undocumented.\n\nMalaria is caused by the protozoan parasites of the genus Plasmodium (of the phylum Apicomplexa), and the transmission vector for human malarial parasite is the female Anopheles mosquito. The P. falciparum variety of the parasite accounts for 80% of cases and 90% of deaths. Children under the age of five and pregnant women are the most vulnerable to the severe forms of malaria.\n\n\nTreatments:\n\nThere are several families of drugs used to treat malaria. Chloroquine was the antimalarial drug of choice for many years in most parts of the world. However, resistance of Plasmodium falciparum to chloroquine has spread recently from Asia to Africa, making the drug ineffective against the most dangerous Plasmodium strain in many affected regions of the world.\n\nThere are several other substances which are used for treatment and, partially, for prevention (prophylaxis). Many drugs can be used for both purposes; larger doses are used to treat cases of malaria. Their deployment depends mainly on the frequency of resistant parasites in the area where the drug is used.\n\nCurrently available anti-malarial drugs include:\n\nArtemether-lumefantrine (Therapy only, commercial name Coartem) \nArtesunate-amodiaquine (Therapy only) \nAtovaquone-proguanil, trade name Malarone (Therapy and prophylaxis) \nQuinine (Therapy only) \nChloroquine (Therapy and prophylaxis; usefulness now reduced due to resistance) \nDoxycycline (Therapy and prophylaxis) \nMefloquine, trade name Lariam (Therapy and prophylaxis) \nPrimaquine (Therapy in P. vivax and P. ovale only; not for prophylaxis) \nProguanil (Prophylaxis only) \nSulfadoxine-pyrimethamine (Therapy; prophylaxis for semi-immune pregnant women in endemic countries as "Intermittent Preventive Treatment" - IPT) \n\nBefore antibiotics, patients with syphilis were intentionally infected with malaria to create a fever. By accurately controlling the fever with quinine, the effects of both syphilis and malaria could be avoided.\n\nPreventions and control\n\nMethods used to prevent the spread of disease, or to protect individuals in areas where malaria is endemic, include prophylactic drugs, mosquito eradication, and the prevention of mosquito bites. There is currently no vaccine that will prevent malaria, but this is an active field of research.

Dengue fever and dengue hemorrhagic fever (DHF) are acute febrile diseases, found in the tropics, with a geographical spread similar to malaria. Caused by one of four closely related virus serotypes of the genus Flavivirus, family Flaviviridae, each serotype is sufficiently different that there is no cross-protection and epidemics caused by multiple serotypes (hyperendemicity) can occur. Dengue is transmitted to humans by the mosquito Aedes aegypti (rarely Aedes albopictus).

I don't think so. Severe and complicated malaria takes time to progress. It can kill due to circulatory shock, kidney failure, haemolysis (breakdown of red blood cells), coma, irregularity of the rhythm of the heart, low blood sugar, fits.

The malaria parasite life cycle involves two hosts.  During a blood meal, a malaria-infected female Anopheles mosquito inoculates sporozoites into the human host .  Sporozoites infect liver cells  and mature into schizonts , which rupture and release merozoites .  (Of note, in P. vivax and P. ovale a dormant stage [hypnozoites] can persist in the liver and cause relapses by invading the bloodstream weeks, or even years later.)  After this initial replication in the liver (exo-erythrocytic schizogony ), the parasites undergo asexual multiplication in the erythrocytes (erythrocytic schizogony ).  Merozoites infect red blood cells .  The ring stage trophozoites mature into schizonts, which rupture releasing merozoites .  Some parasites differentiate into sexual erythrocytic stages (gametocytes) .  Blood stage parasites are responsible for the clinical manifestations of the disease. \n\nThe gametocytes, male (microgametocytes) and female (macrogametocytes), are ingested by an Anopheles mosquito during a blood meal .  The parasites’ multiplication in the mosquito is known as the sporogonic cycle .  While in the mosquito's stomach, the microgametes penetrate the macrogametes generating zygotes .  The zygotes in turn become motile and elongated (ookinetes)  which invade the midgut wall of the mosquito where they develop into oocysts .  The oocysts grow, rupture, and release sporozoites , which make their way to the mosquito's salivary glands.  Inoculation of the sporozoites into a new human host perpetuates the malaria life cycle .

Of course. For example, Manila is the highly urban capital of the Philippines. There are cases of malaria in Manila because of large mosquito populations and poor control measures.\n\nOther times, malaria cases are imported into urban areas, usually in travelers who catch it on vacation and get sick when they arrive at home. We had a mini-outbreak of malaria here in a large city in the US among people who traveled abroad on a church trip.

Malaria is caused by plasmodium falciparum, a bacteria that can be found in mosquito saliva.  As a result of being bitten by the mosquito, p. falciparum causes the individual's red blood cells to burst open, or "lyse".  This is a problem for individuals in Africa, where p. falciparum is common.  Africans have evolved to have their cells "sickle", or change to a crescent shape.  Sickle cells do not lyse in the presence of plasmodium falciparum, but as you probably know, it creates other problems (so it's an evolutionary "trade off").  Sickle cells dont flow through capillaries well, and therefore they cause a log jam in the capillaries, effectively blocking off efficient blood flow to the organ they are supplying.  This can cause those tissues to die in the area of blockage, something called an "infarct".  In sickle cell patients, splenic infarcts are very common, for example, so their spleens often have to be removed.  Hope this helps!!!!
