Luísa Reis-Castro: mosquitoes, race, and class

LuisaReisCastro

As a researcher, I’m interested in the political, ecological, and cultural debates around mosquito-borne diseases and the solutions proposed to mitigate them.

When we received the task, my first impulse was to investigate about the contemporary effects of anthropogenic climate change in mosquito-borne diseases in New Orleans. But I was afraid to make the same mistake that I did in my PhD research. I wrote my PhD proposal while based in the US, more specifically in New England, during the Zika epidemic, and proposed to understand how scientists were studying ecological climate change and mosquitoes in Brazil. However, once I arrived in the country the political climate was a much more pressing issue, with the dismantling of health and scientific institutions.

Thus, after our meeting yesterday, and Jason Ludwig’s reminder that the theme of our Field Campus is the plantation, I decided to focus on how it related to mosquitoes in New Orleans.

The Aedes aegypti mosquito and the yellow fever virus it can transmit are imbricated in the violent histories of settler-colonialism and slavery that define the plantation economy. The mosquito and the virus arrived in the Americas in the same ships that brought enslaved peoples from Africa. The city of New Orleans had its first yellow fever epidemic in 1796, with frequent epidemics happening between 1817 and 1905. What caused New Orleans to be the “City of the Dead,” as Kristin Gupta has indicated, was yellow fever. However, as historian Urmi Engineer Willoughby points out, the slave trade cannot explain alone the spread and persistance of the disease in the region: "Alterations to the landscape, combined with demographic changes resulting from the rise of sugar production, slavery, and urban growth all contributed to the region’s development as a yellow fever zone." For example, sugar cultivation created ideal conditions for mosquito proliferation because of the extensive landscape alteration and ecological instabilities, including heavy deforestation and the construction of drainage ditches and canals.

Historian Kathryn Olivarius examines how for whites "acclimatization" to the disease played a role in hierarchies with “acclimated” (immune) people at the top and a great mass of “unacclimated” (non-immune) people and how for black enslaved people "who were embodied capital, immunity enhanced the value and safety of that capital for their white owners, strengthening the set of racialized assumptions about the black body bolstering racial slavery."

As I continue to think through these topics, I wonder how both the historical materialities of the plantation and the contemporary anthropogenic changes might be influencing mosquito-borne diseases in New Orleans nowadays? And more, how the regions’ histories of race and class might still be shaping the effects of these diseases and how debates about them are framed?

The policy effects vulnerable populations as it deals with those injured, displaced, or otherwise effected by a disaster. While the act doesn’t specifically effect a population that is currently vulnerable, individuals displaced by a disaster are dependent on the help of relief organizations and their community. This leaves them incredibly vulnerable and in need of the support systems detailed in this policy.

The US Department of Veteran Affairs is constantly adjusting to new medical research to provide the most effective care possible. This shows a differing approach to emergency response which is only possible due to the long term nature of this organization, most emergency response groups focus on quick response to disasters which does not allow for the same amount of research and adaptation as the Department of Veteran Affairs.

  • Chernobyl was an unexpected disaster, however several more nuclear disasters have occurred since then. I looked into the safeguards that were changed after Chernobyl and if those had any part in mitigating other nuclear meltdowns. After the explosions several countries and international groups developed nuclear policies that attempted to prevent critical system failures as occurred during the test that caused the reactor to overheat, but many countries refused to adopt additional safeguards that may prevent future disasters.
  • The article described the various zones put into place to keep people away from the most radioactive areas around Chernobyl, I looked into the zones used and the determining factors in determining the sizes of each zone. The initial response determined a zone of 30km around the site, however as scientific understanding of radiation improved the zone was extended to 2600km. This shows the importance of an informed response to prevent further damage after a disaster.

Finally, I researched the effects of low dose radiation poisoning to better understand the medical care needed by those affected. Even low exposure doses can cause lasting damage to organs, or cause cancer and blood related illnesses through the effect of radiation on bone marrow. Those exposed would need frequent medical exams and treatment for the entirety of their lives.

  • Throughout the article it became apparent that the individuals being interviewed were rarely prescribed medication and in some cases did not take their medication. I researched the effectiveness of epilepsy medication and severity of not treating seizures in order to better understand that specific illness.
  • The article was written using data collected in 1988. Since medical knowledge has changed dramatically since then I decided to look into the current medical situation in Turkey. Although it is challenging to find unbiased opinions it appears that even with advances in medical science, cultural traditions remain an integral part in dealing with illness in many places and needs to be understood when dealing with patients who have those beliefs.
  • A majority of the patients interviewed attribute their seizures to a traumatic moment in their past, as I was unaware that epilepsy could be triggered in such a way I looked into the causes of epilepsy. In many cases the cause cannot be identified, however there is significant evidence for epileptic fits being caused by post-traumatic stress as well as neurological trauma and even cardiac issues.
