Malaria – Symptoms, Complications, and Diagnosis

Introduction of Malaria

Malaria may be a disease caused by a parasite that's transmitted to humans through the bites of infected mosquitoes. The mosquito that spreads malaria is named Female Anopheles mosquito. This mosquito carries the parasites named Plasmodium that enters the human bloodstream through the sting. When the mosquito bites the infected person, it sucks the blood containing the parasite. When an equivalent 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. because the parasites mature and grow in number, they begin entering the human bloodstream and infecting the red blood cells. Eventually, they damage the red blood cells and cause symptoms of malaria to occur.

The explanation for malaria fever, Female Anopheles mosquito, thrives under heat and humid weather. For this reason, malaria may be 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 a couple of .1% were from East Mediterranean Region. the number of individuals who didn't receive proper malaria treatment and died in 2018 is on the brink of 405000 and 67% of those people where children. the explanations why these areas are most suffering from this disease are the delayed diagnosis of malaria, lack of data regarding malaria symptoms and its treatment. Children and pregnant women are most susceptible to malaria, as their immunity to fight the disease is weak.

Female Anopheles is the transmitter of malaria. So, it's very rare that malaria fever gets transferred from one person to a different. Though less often, the infection is often passed from a lady to her child during pregnancy or transmitted through transfusion, transplant or use of contaminated syringes.

Malaria Fever is often life-threatening. After the sting, it takes 7 to 30 for the symptoms of malaria fever to surface. this era of seven to 30 days is named the time period. Malaria has several symptoms. But these symptoms vary, counting on the sort of malaria an individual is suffering from. There are two sorts of malaria. Let’s mention these two sorts of malaria and their symptoms.

Uncomplicated Malaria

Symptoms of uncomplicated malaria are almost like that of common flu. Symptoms of uncomplicated malaria are:

1. Fever
2. Chills
3. Sweating
4. Nausea and vomiting
5. Headache
6. Diarrhea
7. Feeling of weakness and illness

When an individual is suffering from uncomplicated malaria, its symptoms initially stay for six to10 hours. They disappear for a few times after this then reoccur every alternate day. The symptoms of malaria fever surface piecemeal which are:

1. In the first stage, the person feels cold and begin shivering
2. In the second stage, the person suffers fever, headache, and vomiting
3. In the last stage, the person sweats tons and stays fatigued

Uncomplicated malaria diagnosis usually gets delayed as symptoms of this sort of malaria fever resemble that of a standard flue. This further results in a delay in malaria treatment and as a result, it gets converted into severe malaria. Let’s understand what severe malaria is.

Severe or Complicated Malaria

The explanation for severe malaria fever is parasite Falciparum. Severe malaria can cause organs dysfunction and even failure. Hence, severe malaria symptoms must be detected as early as possible and therefore the person should tend required malaria treatment. Here are a number of the symptoms of severe malaria.

1. Severe anemia
2. Vital organ dysfunction and failure like kidney dysfunction
3. Jaundice
4. Severe anemia
5. Prostration
6. Lying in prone position
7. Unconsciousness
8. Seizures
9. Confusion
10. Convulsions
11. Deep breathing and respiratory distress

Severe malaria is the major reason behind the high death rate worldwide. The regions that are most suffering from severe malaria are African regions, South-East Asian regions, and the Eastern Mediterranean Region and Western Pacific Region. These areas lack proper malaria treatment and hence, the amount of individuals infected with malaria is high then is that the death rate.

Complications of Malaria

Delayed diagnosis of malaria symptoms and treatment may result in serious complications like:

• Cerebral malaria: Swelling of the brain or brain damage may occur if parasite filled blood cells block small blood vessels to the brain.
• Breathing problems: Fluid gets accumulated within the lungs and results in difficulty in breathing.
• Organ failure: Malaria can cause kidneys or liver failure or rupture the spleen.
• Anemia: thanks to Malaria, red blood cells get damaged which may end in anemia.
• Low blood glucose: Severe sorts of malaria itself can cause low blood sugar.

Diagnosis of Malaria

Malaria is often 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 begin with treatment immediately.

If your doctor suspects that you simply have malaria, he might prescribe you following tests for malaria diagnosis:

1.Thick and Thin Blood Smears

Thin Blood Smears: a little drop of blood is applied and spread onto a glass slide then treated with a special stain to look at under a microscope for the morphology of infected cells and parasites.

Thick Blood Smears: a bigger sample of blood is examined under the microscope in order that the parasites are more likely to be seen. the amount of infected red blood cells also can be calculated to work out the degree to which an individual is infected.

2. Rapid Diagnostic Tests RDT (Rapid Diagnostic Test) may be a strip, which detects malaria Antigens during a blood sample collected. If infected, the color of strip changes indicating that the host is infected.

3. Molecular Test (Polymerase Chain Reaction) This test is completed where microscopic examination isn't possible for malaria. it's wont to determine the species of parasite. it's useful for cases during which the amount of malaria parasites within the blood is low or when there are different types causing the infection.

4. Antibody Testing (Serology) These tests detect antibodies within the blood that are produced by the body in response to malaria infection. they typically cannot diagnose an acute infection but help determine if an individual was previously exposed or not.

5. Susceptibility Testing Malarial parasites became immune to the drugs commonly wont to treat infections. This test is completed to seek out out what proportion the parasite is drug-susceptible.

Prevention from Malaria

Causes of malaria fever are the mosquitoes carrying Plasmodium. These Mosquitoes are most active between dusk and dawn. Following steps are often taken to remain shielded from mosquito bites:

• Wear clothing that covers most of your body
• Apply insectifuge to skin and clothing
• Use an insectifuge that contains DEET or picaridin.
• Use a sprig containing permethrin on clothing.
• Use mosquito nets and bed nets

For people traveling to areas suffering from malaria, taking the above-mentioned preventive measures to become even more important as they lack immunity to fight this disease. they ought to consult their doctor and invite medicine to guard themselves from getting infected with malaria. Often, the drugs given to stop malaria are equivalent because of the drugs used for malaria treatment.

Malaria can relapse. Therefore, people that underwent malaria diagnosis and got it treated should take preventive measures also.

Treatment of Malaria

The purpose of malaria treatment is to destroy plasmodium parasite traveling during a person’s bloodstream. Commonly used drugs to treat malaria after its diagnosis are chloroquine, doxycycline, quinine, and mefloquine. However, the selection of drug depends on factors like:

Kind of parasite that has infected the person

The severity of the symptoms

When the drugs are given supported the type of parasite infecting the person, sometimes it happens that the prescribed medications are incapable of combating the parasite due to parasite’s resistance to the drug. In such cases, doctors are quite one medicine or change the course of malaria treatment.

Malaria may be 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. Till the time R&D is being administered, the planet Health Organization recommends that artemisinin-based combination should be wont to treat uncomplicated malaria.
