STUDY OF MALARIA(e-commerce) We know malaria is a common disease in many countries including Pakistan. We will go through the history of disease to know how biology solved the biological problem concering the cause and transmission of malaria. In ancient times,physicians were familiar with malaria. They described it as a disease of chills and fevers with recurring attacks. They also observed that the disease was more common among people living in low, marshy areas. It was thought that the stagnant water of marshes poisoned the air and as a result of breathing in this “bad air”, people got malaria. This belief led to the name of this disease. The Italian words “mala” means bad and “aria” means air. In the 17th centuary when the New World (America) was discovered, many plants were sent back to Europe to be used as medicines. The bark of tree known as quina-quina was very suitable for curing fevers. It was so beneficial that soon it was impossible to carry enough bark to Europe.
