| - | Malaria and malaria-causing parasites have been known to mankind for thousands of years. Around 7,000-12,000 years ago the increasing temperatures in Africa caused a rise in humidity, thus creating many new water bodies and allowing for agricultural development in the Middle East and North East Africa to occur [11]. This led to the formulation of a favourable climate and area for breeding and transmission of malaria parasites and its carrier, the mosquito. | + | Malaria and malaria-causing parasites have been known to mankind for thousands of years.

| - | Charles Louis Alphonse Laveran, a French army surgeon stationed in Constantine, Algeria, was the first to notice parasites in the blood of a patient suffering from malaria. This occurred on the 6th of November 1880. For his discovery, Laveran was awarded the Nobel Prize in 1907 [7]. | + | Charles Louis Alphonse Laveran, a French army surgeon stationed in Constantine, Algeria, was the first to notice parasites in the blood of a patient suffering from malaria.

| - | Camillo Golgi, an Italian neurophysiologist, established that there were at least two forms of the disease, one with tertian periodicity (fever every other day) and one with quartan periodicity (fever every third day). He also observed that the forms produced differing numbers of merozoites (new parasites) upon maturity and that fever coincided with the rupture and release of merozoites into the blood stream. He was awarded a Nobel Prize in Medicine for his discoveries in neurophysiology in 1906 [5]. | + | Camillo Golgi, an Italian neurophysiologist, established that there were at least two forms of the disease, one with tertian periodicity (fever every other day) and one with quartan periodicity (fever every third day).

| - | The Italian investigators Giovanni Batista Grassi and Raimondo Filetti first introduced the names Plasmodium vivax and P. malariae for two of the malaria parasites that affect humans in 1890 [9]. Laveran had believed that there was only one species, Oscillaria malariae. An American, William H. Welch, reviewed the subject and, in 1897, he named the malignant tertian malaria parasite P. falciparum. | + | The Italian investigators Giovanni Batista Grassi and Raimondo Filetti first introduced the names Plasmodium vivax and P. malariae for two of the malaria parasites that affect humans in 1890 (Mandal, 2016).
