Historical Origins of Global Health in Understanding Current Issues in Malaria
Powerful social forces among humans completely shape the way
we interact with diseases found naturally in our environment. International
Health as we know it now has arisen from a history of changes in social forces
that led to devastating disease outcomes. Lifestyle, economic structure, city
scheme, government, and class organization have all contributed to the human
history of health.
I think one of the most fascinating examples of this is the
case of Malaria and the development of quinine. I research Malaria, and I like
to think about it as an organism trying to live a long time. Plasmodium needs the human host and
mosquito vector to survive, so it would ideally never kill the host. In fact,
the disease has been around almost as long as humans as a species has, and the
two have lived relatively peacefully together for thousands of years. It’s when
large scale social change occurred that Malaria started to be a problem. We see
this when colonial Europeans began to make changes in regions of frequent (but not
deadly) Malaria infection: “Rapid development, the building of cities and
clearing of forests, and inadequate drainage and sewage disposal exacerbated
malaria infection rates throughout the colonial world, starting in the
Americas, from the 16th century onward” (Birn, et al).
It was how close the colonial powers had people living that
made malaria a problem, and Plasmodium
has not since had enough time to slow down its infection rate to accommodate
the newer arrangement. Africa was the “white man’s grave” because of malaria,
and when the white man came into Africa and other “tropical” regions with
natural infection rates and changed the way the Africans or South Americans or
Southeast Asians lived, it became the curse of these people too (Birn et al).
This is the historical context of malaria research that
still affects how International Health and individual organizations approach
the issue today. Part of the funding comes simply from a European guilt about
the origins of the devastating disease. Unfortunately, it seems impossible to
return to the spread out pastoral structure which is the optimum for low
malaria mortality. Additionally, the drugs that have been developed to treat
the disease have changed the organism greatly. How much the parasite has become
resistant varies greatly from place to place because treatment is in the hands
of individual governments.
This can be
devastating because we sometimes forget that the parasite wants to live. It
will obviously do anything to keep on living, just as we would. So when local
politicians use promises of new drug regimes to help their people eradicate
malaria to get put into power, they underestimate the ancient Plasmodium. Political interests, as well
as well meaning but misguided aid campaigns, public health policies, and
research efforts have all contributed to a very variable and sometimes quite
grim resistant malaria outlook.
To visualize this, I have my favorite map ever made: http://www.pnas.org.offcampus.lib.washington.edu/content/106/45/18883.full
As you can see, some cities and some countries have a pack
of resistant strains, whereas some only have a couple. The very identity of the
parasite has been changed in these places because of human social
organizations.
India, a former British colony from the 1820’s to 1950, now
faces almost all of the chloroquine and amodiaquine resistant strains of
malaria. This is a problem because there really are not very many drugs
available to treat malaria in the first place, and India has few weapons
remaining. As Birn et al argue, this problem’s colonial roots inform the way it
can be approached in the international health arena. In the description of a novel case of chloroquine resistant
malaria in Northern India from, 1984, the unease of the situation is clear.
“The patient stated that there was an awareness in Surat of a change in the
type of malaria recently occurring there. This case demonstrated that malignant
tertian malaria resistant to chloroquine can be acquired in Gujarar, an area
hitherto considered free from this problem, and marks the further spread of
this infection in the Indian sub-continent” (Mahoney, et al).
Until the late 20th century, public health policy
in India, backed by global health goliaths like WHO and others, was focused on
malaria eradication. To accomplish this, they focused on acquiring and administering
every drug there was. This was a mistake. India now faces these multiple drug
resistant strains of malaria, and the real solutions have been left neglected.
Now turning to the colonial history of malaria and India itself, public health
policy there has started to look at solutions that stem from the community.
Too-close living quarters and stagnant water are the aggravators of malaria
endemic intensity. These conditions arose from response to British colonial and
economic power, and can only be changed by more social change.
Our readings have focused on the origins of global health.
They argue that what we have currently, as in the case of India, is a mess of
different ideas and interests resulting in an array of complicated results.
Governments have an economic interest in health, which has given rise to
corporations with an economic interest in health. These powerful social forces
working together can change the health of masses of people. This is a long way
from public health origins in Imperialism and Industrialism, but these
foundations can inform the ultimate goal of global health. I think, like in
India’s cases, it is still possible to see how preserving lucrative trade is a
priority in health and sanitation. The quick fixes of drugs allowed laborers to
continue working, goods to remain uncontaminated, and business to go on as
usual. Not to mention that the production and sale of pharmaceuticals is a
trade in and of itself.

The paragraph that stood out to me the most was the second paragraph that discusses the way plasmodium, which is a parasitic protozoan that causes malaria, needs the human host and mosquito vector to survive. For this reason, the author writes that plasmodium would never intentionally kill the host. Sadly, this is not the outcome that we see today. Malaria, according to WHO in 2010 killed nearly 1.2 million people. It is interesting to see the author write that for over thousands of years malaria and the human race had been living together peacefully. So, why is it that malaria is so deadly now? Her answer to this question is the affects of colonialism with the rapid development of cities, the clearing of forests, the inadequate drainage and sewage disposal starting in America in the 16th century that made the issue of plasmodium and malaria a problem leading to death. Due to the advancement of technology in terms of medicine to cure malaria as well as the advancement of human knowledge and the constant over population of more people living closer together, the malaria protozoan has not been able to slow down its infection rate. With the treatment of certain types of malaria, comes much resistance to various strands of the disease as the parasite changes and forms immunities.
ReplyDeleteThe way the author writes her post shows me a completely different intake on the disease. She treats the disease almost as the victim in the way where it as well wants to live and it as well is in a fight for its life. Just as much as we are trying to kill this parasite, it is trying to adapt and change and form into new strands in order to live. It almost makes me sad that humans used to live peacefully with plasmodium and now we are in war to abolish plasmodium from the world. As humans are developing at a much quicker rate, the plasmodium cannot keep up and for this we must kill it before it kills us. Of course in the end, a parasite is not a human and we cannot feel about destroying something that is killing our people. With the resistant malaria strains and the aggravators of malaria intensity as too-close living conditions and stagnant water, the author writes that only solution is more social change. Maybe as we change socially, malaria will too and one day again we will be able to live peacefully with plasmodium.
