Malaria is a potentially fatal disease. Especially in countries with tropical climates and developing countries. Malaria plays an important role in the health of the population. Is an infection of red blood cells by a parasite that destroys them.

What causes malaria?
Malaria is caused by infection with the microscopic parasite plasmodium. There are over 150 species of Plasmodium that infect different vertebrates, but only four (P. falciparum, P. vivax, P. ovale and P. malariae) infect humans. The two most common species are P. causing acute falciparum malaria and may lead to death and P. vivax which causes infections and recurrent debilitating but rarely fatal.
The plasmodium is transmitted to humans through bites from Anopheles mosquitoes infected with the parasite.
In humans, the parasites migrate to the liver where they mature and then enter the bloodstream and infect red blood cells.
The parasites multiply within red corpuscles, after 48 to 72 hours, break and infect more red blood cells.
If a mosquito carrying the parasite is not piqa an infected person can infect others.
What are the symptoms of malaria and how long after they appear?
The symptoms of malaria are similar to the flu. They usually occur between 12 to 30 days after the bite of the mosquito.
The symptoms are:

  • Sudden and violent chills
  • Sweating
  • Depletion
  • Headache and muscle
  • High fever (about 47 degrees)
  • Vomiting and nausea
  • Diarrhea and jaundice
  • Delirium


How is malaria diagnosed?
The diagnosis of malaria is made through a microscope to identify Plasmodium parasites in a blood sample.

How is malaria?
Malaria is treated with drugs that interfere with the life cycle or metabolism of the parasite. The use of these drugs depends on the type of malaria and where the disease was acquired.
Some types of malaria are resistant to medicines in certain areas, treatment should start sooner, although the disease is mild, to prevent complications and death.

Urticaria happens when there is a trigger, normally an allergen (which causes an allergic reaction) and causes the body to release histamine in our body. Histamine causes tiny blood vessels known as capillaries leak fluid, fluid accumulates in the skin and causes a rash.
urticaria

Hives can be caused by many things, including:

Allergic reaction, for example, to certain foods or bee or wasp stings.
The skin comes into contact with something irritating, such as latex, chemicals, or nettles.
Drugs, usually anti-inflammatory drugs (NSAIDs), used to treat pain and fever, and ACE inhibitors, used to treat high blood pressure.
Physical triggers, such as skin pressure, low temperature, sunlight and water.
However, in about 50% of cases, does not identify any cause.

Urticaria is a common disease that affects one in six people at some point in their lives. It is more likely to affect more children and women.
The rash usually disappears after a few days, but some cases may last longer. It is not contagious.
Hives should not continue for more than six weeks is called acute urticaria.

Chronic urticaria

If episodes of urticaria lasting more than six weeks is called chronic urticaria. Chronic urticaria is much rarer than acute urticaria, affects one in every 1,000 people.

The causes of most cases of chronic urticaria is unknown, but believed to be a problem with the person’s immune system.

About 50% of people with chronic urticaria and 25% of people with acute urticaria, also get a related condition called angioedema. The Angioedema involves swelling in the deeper layers of skin.

The swelling causes a burning sensation and often occurs in the neck and face, fingers and toes, and men in genitals.

Anaphylaxis

In rare cases, hives can be one of the first symptoms of an extreme allergic reaction known as anaphylaxis. As the reaction proceeds, throat and airways swell, making breathing difficult, and the person experiences a massive drop in blood pressure.

Anaphylaxis is a life-threatening condition and requires emergency treatment.
