QUESTION

Who was the discoverer of malaria?

ANSWER

Malaria has been known to humans since ancient times, though what exactly caused it and how it was transmitted was not known. The parasite which causes malaria, from the genus Plasmodium, was first observed in the blood of a patient who had died from the disease by Charles Louis Alphonse Laveran, a French physician working in Algeria. This was in 1880; a few years later, in 1897-1898, a British army doctor called Ronald Ross showed that malaria could be transmitted via the bite of a mosquito. Both doctors eventually received the Nobel Prize for their discoveries.

Malaria Origins

QUESTION

What is the origin of malaria?

ANSWER

Malaria is caused by a single-celled parasite of the genus Plasmodium. There are five difference species of Plasmodium which infect humans – these all likely evolved from various different species of Plasmodium which infect other primates, such as gorillas (for P. falciparum) and macaques (P. vivax, P. knowlesi, possibly other types as well). This happened many thousands of years ago; humans have been plagued by malaria since before records began. In fact, the first recorded mention of the symptoms of malaria come from ancient China, in a manuscript dated to 2700 years before the common era, or almost 5000 years ago.

However, understanding that malaria was caused by a microscopic parasite, which is transmitted by mosquitoes, occurred much more recently; the Plasmodium parasite was first observed in the blood of a person who died from malaria in 1880 by the French physician Charles Louis Alphonse Laveran. A few years later, in 1897/1898, a British physician, Ronald Ross, demonstrated that the parasite could be transmitted between hosts via the bite of an infected mosquito. Both physicians eventually won Nobel Prizes for their work.

QUESTION

What is malaria and when was it diagnosed?

ANSWER

Malaria is a disease caused by a single-celled parasite of the genus Plasmodium. Five types of malaria infect humans: P. falciparum, P. ovale, P. vivax, P. malariae and P. knowlesi. It was first observed in the blood of a patient who had died of malaria in 1880 by Charles Louis Alphonse Laveran, a French physician working in Algeria.

First Cases of Malaria

QUESTION

What is the first infected person with Plasmodium?

ANSWER

Plasmodium, the single-celled parasite which causes malaria, has been infecting humans since ancient times. In fact, the first written reference to its symptoms dates back almost 5000 years, to an ancient Chinese manuscript! It was also known from the writings of other ancient peoples, such as the Greeks, Romans and Egyptians; when Europeans arrived in the Americas, they found that local tribes had long recognised the dangers of malaria, and already had natural remedies for fever, including the bark of the cinchona tree, which was later used to make quinine (a moden anti-malarial). As such, it is impossible to say now who the first person infected with Plasmodium was, but it definitely occurred many thousands of years ago.

However, it was only until the late 19th century that people understood that Plasmodium parasites caused malaria, and knew how to observe the infection in the patient’s blood. This was done was Charles Louis Alphonse Laveran, a French physician working in Algeria. As such, you could argue that the first person known to have Plasmodium was the patient he observed the parasite within, when he first described Plasmodium. Unfortunately, the patient had died of the disease; Laveran examined the blood after the patient had perished. I am not sure the patient’s name was recorded.

QUESTION

How was malaria discovered?

ANSWER

Malaria has long been known to human populations from across the world. In fact, the first mention of the symptoms of malaria comes from an ancient Chinese manuscript from 2700 BCE! However, the actual cause and mechanism of transmission of the disease was only discovered in the 19th century.

It was Charles Louis Alphonse Laveran, a French physician working in Algeria, who first observed the parasites that cause malaria in 1880, by looking at the blood of a patient that had recently died of malaria. However, at this point, it still wasn’t understood how malaria was transmitted. That was not discovered until 1897, when Ronald Ross, a British physician dedicated to curing malaria, observed malaria parasites in a mosquito that had been experimentally fed the blood of a patient infected with malaria. Working in India, Ross also later showed that mosquitoes could also transmit malaria to birds, if they had previously fed on the blood of birds which had malaria. In this way, he showed that mosquitoes of the genus Anopheles are responsible for transmitting malaria between hosts.

First Malaria Outbreak

by

QUESTION

When was the first ever outbreak of malaria?

ANSWER

Malaria has actually been known in human populations for thousands of years, so the first ever outbreak occurred long before any records were kept. The ancient Chinese recorded the symptoms of malaria in a medical manuscript which dates back to 2700 BCE, so almost 5000 years ago!

The symptoms of malaria were also known to the ancient Romans, Greeks, Egyptians and native peoples of the Americas, though none of them fully understood the cause of the disease or how it was transmitted. That information was discovered in the late 19th century, by Charles Louis Alphonse Laveran, who first observed malaria parasites in the blood of a patient and attributed them to the disease, and by Ronald Ross, who demonstrated that the malaria parasite was transmitted by mosquitoes.

What year was the cause of malaria discovered?

QUESTION

When did they find out that a bug bite caused malaria, and what year was that?

ANSWER

In 1880, Charles Louis Alphonse Laveran observed that malaria was caused by a parasite in the blood; it wasn’t until 1897-1898 that Ronald Ross, a British Army medical doctor, discovered that the parasite could be transmitted between hosts (he used birds for his experiments) by mosquitoes.

QUESTION

When was malaria first detected?

ANSWER

Humans have known about malaria as a disease for thousands of years. The earliest written record of malaria is from ancient China, 2700 BCE. The ancient Romans and Greeks also described the symptoms of malaria, though none of these ancient people knew the true cause or had identified specifically how it was transmitted. This was first achieved in the 19th century, first in 1880 by Charles Louis Alphonse Laveran, who observed the parasites that cause malaria in the blood of a patient. A few years later, in 1897/1898, Ronald Ross discovered that the parasites were transmitted between hosts via mosquitoes, thus laying the foundations for future decades of malaria control efforts.

Who Discovered Malaria?

QUESTION

Who discovered malaria?

ANSWER

People have known about malaria for thousands of years—the first record of it comes from 2700 BCE, in an ancient Chinese medical text. Other ancient peoples, such as the Egyptians, Greeks and Romans, also knew the symptoms associated with malaria. But it wasn’t until the 19th century that the causes of malaria were understood. In 1880, a French physician named Charles Louis Alphonse Laveran first saw the parasites that cause malaria in the blood of a patient. By 1886, Camillo Golgi, an Italian physiologist, had observed that there were at least two separate types of malaria, which produced different length cycles of fever during the clinical presentation. These two forms were later called Plasmodium vivax and Plasmodium malariae. It wasn’t until more than a decade later, in 1897/1898, that the method of transmission of malaria was first understood – Ronald Ross, a British army doctor, showed that malaria could be passed from a human patient to a mosquito vector, and also between infected hosts using mosquitoes. He won the Nobel Prize for medicine for his work in 1902.

Since then, research on malaria has expanded exponentially, with particular attention giving to understanding ways in which the parasite can be therapeutically halted, thus leading to the discovery of new malaria medications.

How did it get the name “malaria”?

by

QUESTION

How did malaria get its name?

ANSWER

The word “malaria” comes from Italian, “mala aria” which literally translates to “bad air”. This came from the ancient association, traced back as far as the ancient Greeks and Romans, that the disease was associated with swampy, marshy areas where the air smelled bad.

The mechanism of transmission was not known back then, nor did they know anything about infectious disease agents like bacteria, viruses or the single-celled protozoa like what causes malaria. So they believed it was the air itself that caused the infection, hence giving malaria its name. The protozoan which causes malaria was not discovered until 1880 when Charles Louis Alphonse Laveran observed the parasites in a patient; it was a few years later, in 1897/1898, that Ronald Ross discovered that mosquitoes transmitted malaria between human hosts. He won a Nobel Prize for this discovery in 1902.
