malaria is caused by protozoa - Plasmodium species. There are at least four malarial parasites; P. vivax, P. ovale, P. malaria and P. falciparum.
P. falciparum can invade red blood cells of all ages, may also be drug-resistant and is responsible for most severe and acute life-threatening malignant tertian malaria with highest mortality.
Plasmodium, in form of sporozoites, travels in blood to the liver and spleen, where it reproduces and infects red blood cells.
1,544 cases of malaria
In 2012, South Carolina reported a total of 11 cases of malaria. These cases were primarily linked to travel, as South Carolina is not endemic for malaria. The state typically sees a low incidence of malaria due to its climate and public health measures.
Asia
More than 1000 malaria cases have been recorded in Mulago Hospital this year.
There are bout 20 million cases of malaria annually worldwide. This is probably gross underestimate. So many cases are not reported. Actual figure is probably 50 million cases annually.
Plasmodium vivax causes 8 out of 10 cases of malaria. Fortunately this form of malaria is usually not lethal.
Every year 5,800,000 cases of malaria are reported and 3,366 deaths caused by malaria in Mozambique.
There are about 20 million cases of malaria annually. About 6,00,000 patients die of malaria annually. Morbidity and mortality wise this is very dangerous disease.
Clinical malaria refers to the symptomatic presentation of malaria, which includes fever, chills, and other flu-like symptoms caused by the Plasmodium parasite. Severe malaria, on the other hand, is a critical condition characterized by life-threatening complications such as cerebral malaria, severe anemia, respiratory distress, or organ failure. While all cases of severe malaria are considered clinical malaria, not all clinical malaria cases progress to severe forms. Prompt diagnosis and treatment are essential to prevent progression to severe malaria.
Mild cases can be treated with ibuprofen. More severe cases can be treated with malaria medication.
Malaria is common in topical ad subtropical zones. The malaria has selected the people with sickle cell anaemia. Although person with sickle cell anemia can have malaria, the carrier, or the person with sickle cell trait is resistant to malaria.
As of now, malaria is primarily found in certain regions of the world rather than in all U.S. states. In the United States, malaria was largely eliminated by the 1950s, but sporadic cases can occur, particularly in states with warmer climates like Florida, Texas, and parts of California. However, the majority of malaria cases in the U.S. are reported in travelers returning from areas where malaria is endemic, primarily in sub-Saharan Africa and Southeast Asia.
