Malaria is not only blood disease, it also hides in the spleen

Malaria is not only a blood disease, it also hides in the spleen

The malaria parasite is known to hijack red blood cells in its potentially lethal discovery, which is spread by a female anaphylaxis mosquito bite. Recently, scientists have found that the malaria parasite Plasmodium is also hidden within the human spleen, which filters the blood.

“What we discovered is that there are some people circulating who have malaria parasites of the spleen and not their [circulating] blood,” said lead author Steven Kho, from Menzies Faculty of Wellbeing Analysis. This implies that they cannot be picked up by screening packages that search for evidence of parasites in the circulating blood. According to Dr. Kho-, people with contaminated spleen do not have any symptoms, so they are unlikely to seek medical treatment. This suggests that they are carriers and if the mosquito bites them they can spread the disease to others.

Malaria Life Cycle

Malaria parasites spread to the bloodstream by starving anopheles mosquito bites. The malaria parasite spreads from one person to another through the saliva of a mosquito, a blood-sucking female anopheles of a person with malaria disease.

Within a few days, the parasite travels through the bloodstream until it invades the liver. After reaching the liver, the malaria parasite turns into a second stage which starts infecting the red blood cells and killing the red blood cells. The symptoms of headache, fever, and nausea are seen throughout this process.

Malaria disease also triggers excessive anemia, shortness of breath, organ failure, coma, and loss of life when in a critical state.

In 2019, there have been around 229 million cases of malaria disease worldwide and 4, 09, 000 patients have died, most of them children and pregnant women.

Spleen and Malaria

The spleen, located on the left side of the human body, plays an important role in the immune system. As the blood enters the spleen, irregular and dysfunctional blood cells are eliminated. The above process of spleen keeps the spleen under different types of stress.

When the global team of scientists examined the spleen tissue, they were stunned. Tissue was collected from the spleen of 22 people living in Timika, Indonesia’s Papua province. These were people without symptoms but were removed after a spleen ruptured during an accident. These people did not have blood malarial parasites, but large amounts of Plasmodium vivax and Plasmodium falciparum were found in their spleen.

A closer examination of the spleen tissue additionally confirmed an improved variety of young red blood cells, often called reticulocytes. These young blood cells present the proper breeding floor for P. vivax, the dominant species of the parasite in this location.

According to Justin Bode of the Eliza Corridor Institute – The invention of the hidden reserves of malaria parasites within the human organ spleen was an “entertainment changer”.
