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?

This article covers the investigation procedure following a tragedy, and how the outcomes of these investigations tend to be muddled due to factors outside of logic and reason. These influencing factors make it difficult to draw conclusions as to what contributing factors were most significant in the damage sustained during the tragedy, and how to best avoid them in the future. For this reason, it addresses how difficult it is to improve disaster-response when so little useful information can be gleaned from the modern investigatory procedure.

They use aggregated interviews wherein all or many of the survivors repeat the same issues with long term effects of the disaster.

They also study the socioeconomic longterm effects of the disaster by comparing New Orleans years later to the past, showing how permanent an effect the storm had despite eventual recovery.

They also used sociological surveys that showed widespread mental health disorders that developed throughout the survivor population in greater frequency than that of the normal population due to the events that occured.

"This realization (of having to face Nuclear disasters) marks a major shift in our thinking about nuclear risk, away from accident prevention, and toward accident mitigation and more rigorous emergency preparedness."

"Severe nuclear accidents may thus require international instiutions to coordinate their mitigation."

"...the 'culture of control' (that is, attempts to regulate every last action of the operating staff) is too rigid to account for all imaginable situations... it would appear to be in the interest of voerall nuclear safety to log and learn from these incidents, rather than conceal them."

“Despite these facts, the risk for outbreaks after disasters is frequently exaggerated by both health offi cials and the media. Imminent threats of epidemics remain a recurring theme of media reports from areas recently affected by disasters, despite attempts to dispel these myths.”

“The risk for communicable disease transmission after disasters is associated primarily with the size and characteristics of the population displaced, specifi cally the proximity of safe water and functioning latrines, the nutritional status of the displaced population, the level of immunity to vaccine-preventable diseases such as measles, and the access to healthcare services” 

“Disaster-related deaths are overwhelmingly caused by the initial traumatic impact of the event. Disaster-preparedness plans, appropriately focused on trauma and mass casualty management, should also take into account the health needs of the surviving disaster-affected populations.”
