African people no longer exempt from malaria

The international team of scientists has found that Africans no longer have the ability to immunity Plasmodium vivax malaria infection as before.

The results of this study were 'shocking' to the scientific world.

In the report published in The United States Academy of Sciences the latest issue, a group of scientists from France, the United States and Madagascar said that Plasmodium vivax malaria is the main culprit in malaria, mainly in the Asia and South America.

Previously, it was argued that people on Duffy protein deficiency have a natural immunity to Plasmodium vivax malaria infection. Because without Duffy protein, malaria will not be able to enter the bloodstream.

The blood of most Africans is negative for Duffy protein. This is the reason why very few African people have Plasmodium vivax malaria infection.

However, after observing the parts of Madagascar, scientists found that some Duffy-negative residents could also get Plasmodium vivax malaria infection.

This suggests that Dufy protein is no longer an indispensable condition for transmitting Plasmodium vivax malaria infection. But now, scientists still do not understand their specific mechanism.

According to scientists, an average of 7,000 to 8,000 cases of Plasmodium vivax malaria are detected annually.
