The mosquito that spreads malaria is called Female Anopheles mosquito. This mosquito carries the parasites named Plasmodium that enters the human bloodstream through the mosquito bite. When the mosquito bites the infected person, it sucks the blood containing the parasite. When the same mosquito bites a healthy person, it releases Plasmodium into the blood of that person. Once the parasite enters the human bloodstream, it travels to the liver where it matures and multiplies in number. As the parasites mature and grow in number, they start entering the human bloodstream and infecting the <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/www.lalpathlabs.com\/pathology-test\/red-blood-cells-rbc-count\">red blood cells<\/a><\/span>. Eventually, they damage the red blood cells and cause symptoms of malaria to occur.<\/p>\n<p>The <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/www.lalpathlabs.com\/blog\/what-is-malaria-fever\/\">cause of malaria fever<\/a><\/span>, Female Anopheles mosquito, thrives under hot temperature and humid weather conditions. For this reason, malaria is a common disease in tropical and subtropical regions. In 2018, approximately 228 million cases of malaria were registered out of which 93% belonged to the African Region, 3.4% cases were from the South-East Asian Region and 2.1% were from East Mediterranean Region. The number of people who did not receive proper malaria treatment and died in 2018 is close to 405000 and 67% of these people where children. The reasons why these areas are most affected by this disease are the delayed diagnosis of malaria, lack of information regarding malaria symptoms and its treatment. Children and pregnant women are most vulnerable to malaria, as their immunity to fight the disease is weak.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-large wp-image-4494\" src=\"https:\/\/www.lalpathlabs.com\/blog\/wp-content\/uploads\/2020\/02\/523915086sst1582193699-1024x683.jpg\" alt=\"Malaria\" width=\"950\" height=\"634\" \/><\/p>\n<p>Female Anopheles is the transmitter of malaria. So, it is very rare that malaria fever gets transferred from one person to another. Though less often, the infection can be passed from a woman to her child during pregnancy or transmitted through blood transfusion, organ transplant or use of contaminated syringes.<\/p>\n<p>Malaria Fever can be life-threatening. After the mosquito bite, it takes 7 to 30 for the symptoms of malaria fever to surface. This period of 7 to 30 days is called the incubation period. Malaria has several symptoms. But these symptoms vary, depending on the type of malaria a person is affected by. There are two types of malaria. Let\u2019s talk about these two types of malaria and their symptoms.<\/p>\n<p><strong><span style=\"font-size: 14pt;\">Uncomplicated<\/span> <span style=\"font-size: 14pt;\">Malaria<\/span><\/strong><\/p>\n<p>Symptoms of uncomplicated malaria are similar to that of common flu. Symptoms of uncomplicated malaria are:<\/p>\n<ul>\n<li>Fever<\/li>\n<li>Chills<\/li>\n<li>Sweating<\/li>\n<li>Nausea and vomiting<\/li>\n<li>Headache<\/li>\n<li>Diarrhoea<\/li>\n<li>Feeling of weakness and illness<\/li>\n<\/ul>\n<p>When a person is affected by uncomplicated malaria, its symptoms initially stay for 6 to10 hours. They disappear for some time after this and then reoccur every alternate day. The symptoms of malaria fever surface in stages which are:<\/p>\n<ul>\n<li>In the first stage, the person feels cold and start shivering<\/li>\n<li>In the second stage, the person suffers fever, headache, and vomiting<\/li>\n<li>In the last stage, the person sweats a lot and stays fatigued<\/li>\n<\/ul>\n<p>Uncomplicated malaria diagnosis usually gets delayed as symptoms of this type of malaria fever resemble that of a common flue. This further leads to a delay in malaria treatment and as a result, it gets converted into severe malaria. Let\u2019s understand what severe malaria is.<\/p>\n<p><strong><span style=\"font-size: 14pt;\">Severe or<\/span> <span style=\"font-size: 14pt;\">Complicated<\/span> Malaria<\/strong><\/p>\n<p>The cause of severe malaria fever is parasite Falciparum. Severe malaria can lead to organs dysfunction and even failure. Hence, severe malaria symptoms must be detected as early as possible and the person should be given required malaria treatment. Here are some of the symptoms of severe malaria.<\/p>\n<ul>\n<li>Severe anaemia<\/li>\n<li>Vital organ dysfunction and failure like kidney dysfunction<\/li>\n<li>Jaundice<\/li>\n<li>Severe anaemia<\/li>\n<li>Prostration<\/li>\n<li>Lying in prone position<\/li>\n<li>Unconsciousness<\/li>\n<li>Seizures<\/li>\n<li>Confusion<\/li>\n<li>Convulsions<\/li>\n<li>Deep breathing and respiratory distress<\/li>\n<\/ul>\n<p>Severe malaria is the major reason behind the high mortality rate worldwide. The regions that are most affected by severe malaria are African regions, South-East Asian regions, and Eastern Mediterranean Region and Western Pacific Region. These areas lack proper malaria treatment and hence, the number of people infected with malaria is high and so is the death rate.<\/p>\n<p><span style=\"font-size: 14pt;\"><strong>Complications<\/strong><\/span><\/p>\n<p>Delayed <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/www.lalpathlabs.com\/blog\/rapid-diagnostic-test-for-malaria\/\">diagnosis of malaria<\/a><\/span> symptoms and treatment can result in serious complications like:<\/p>\n<ul>\n<li><strong>Cerebral malaria:<\/strong> Swelling of the brain or brain damage may occur if parasite filled blood cells block small blood vessels to the brain.<\/li>\n<li><strong>Breathing problems:<\/strong> Fluid gets accumulated in the lungs and leads to difficulty in breathing.<\/li>\n<li><strong>Organ failure:<\/strong> Malaria can cause kidneys or liver failure or rupture the spleen.<\/li>\n<li><strong>Anaemia:<\/strong> Due to Malaria, red blood cells get damaged which can result in anaemia.<\/li>\n<li><strong>Low blood sugar:<\/strong> Severe forms of malaria itself can cause low blood sugar.<\/li>\n<\/ul>\n<h2><span style=\"font-size: 14pt;\"><strong>Diagnosis<\/strong><\/span><\/h2>\n<p>Malaria can be prevented from becoming severe and life-threatening, if malaria symptoms are diagnosed and treatment is started on time. Anyone showing signs of malaria should get the tests done and start with treatment immediately.<\/p>\n<p>If your doctor suspects that you have malaria, he might prescribe you following tests for malaria diagnosis:<\/p>\n<ol>\n<li><strong>Thick and Thin Blood Smears<\/strong><\/li>\n<\/ol>\n<p><strong>Thin Blood Smears:<\/strong> A small drop of blood is applied and spread onto a glass slide and then treated with a special stain to examine under a microscope for the morphology of infected cells and parasites.<\/p>\n<p><strong>Thick Blood Smears: <\/strong>A larger sample of blood is examined under the microscope so that the parasites are more likely to be seen. The number of infected red blood cells can also be calculated to determine the degree to which a person is infected.<\/p>\n<p>2.<strong> Rapid Diagnostic Tests\u00a0<\/strong>RDT (Rapid Diagnostic Test) is a strip, which detects malaria Antigens\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0in a blood sample collected.

These Mosquitoes are most active between dusk and dawn. Following steps can be taken to stay protected from mosquito bites:<\/p>\n<ul>\n<li>Wear clothing that covers most of your body<\/li>\n<li>Apply insect repellant to skin and clothing<\/li>\n<li>Use an insect repellent that contains DEET or picaridin.<\/li>\n<li>Use a spray containing permethrin on clothing.<\/li>\n<li>Use mosquito nets and bed nets<\/li>\n<\/ul>\n<p>For people travelling to areas affected by malaria, taking the above-mentioned preventive measures to become even more important as they lack immunity to fight this disease. They should consult their doctor and ask for medicine to protect themselves from getting infected with malaria. Often, the drugs given to prevent malaria are the same as the drugs used for malaria treatment.<\/p>\n<p>Malaria can relapse. Therefore, people who underwent malaria diagnosis and got it treated should take preventive measures as well.<\/p>\n<p><span style=\"font-size: 14pt;\"><strong>Treatment<\/strong><\/span><\/p>\n<p>The purpose of <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/www.lalpathlabs.com\/pathology-test\/malaria-parasite-confirmation\">malaria treatment<\/a><\/span> is to destroy plasmodium parasite travelling in a person\u2019s bloodstream. Commonly used drugs to treat malaria after its diagnosis are chloroquine, doxycycline, quinine, and mefloquine. However, the choice of drug depends on factors like:<\/p>\n<ul>\n<li>Kind of parasite that has infected the person<\/li>\n<li>The severity of the symptoms<\/li>\n<\/ul>\n<p>When the medicine is given based on the kind of parasite infecting the person, at times it happens that the prescribed medications are incapable of combating the parasite because of parasite\u2019s resistance to the drug. In such cases, doctors are more than one medicine or change the course of malaria treatment.<\/p>\n<p>Malaria is a disease that causes severe illness and death in tropical and subtropical counties. Therefore, several international labs are conducting research and testing to develop a vaccine to fight Malaria.
