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?

In Baltimore, researchers found that racism and poverty especially affected African Americans without insurance. In order to address this, they removed boundaries to care within the medical system and community so that poor patients could receive the care they needed without economic trouble. Along with this, they also established a system that relied on the community as a whole for care, taking the social stigma away from AIDS/HIV care and building ties as a whole. Within a few years, many disparities disappeared among the studied population.

Another study in rural Haiti was used to develop the PIH model of care. This model relies on an accompagnateur who is trained in drug delivery and supportive care. This allows care to be given within a village, not a clinic, and improves access to care. This model has worked to improve patient care and outcome in Haiti, Peru, and Boston.

In Rwanda, structural violence has perpetuated to transmission of disease from mother to child for decades. Access to resources such as clean water and formula, along with public health agencies promoting the merits of breastfeeding, have made it challenging to address MTCT. However, when researchers asked mothers if they would like these resources, they were eager to receive them and wanted to help in preventing further transmission.

The data acquired in this study can be used not only for improvement in policies and training for healthcare workers, but also to examine the risk factors for the disease. One example is the age and gender disparities in those nfected. These could be explained by the typical age and gender of healthcare workers, but could also show a trend in risk when coupled with patient data. The data on the districts and their infection rates can be used to help pinpoint the origin of infection.

As far as persuasive goes, the entire film was very convincing of the fact that the doctors were under-resourced and over-worked. The part where the doctors were trying to perform a surgery and didn't have the right kind of drill to relieve the pressure in the brain was pretty compelling. Here we would never consider drilling into someone's brain without the proper sterilization, apparatus, or drill, but in such a low resource clinic, its the only option. That just shows how desperate the doctors were to perform their craft andbest serve their patients. Another part that was convincing was the portion where the doctors argued about reusing gloves. It was a bit hard to understand the argument, as the concept is just baffling to me as a hcp, but the fact that they had to disagree over washing and reusing gloves is proof of their desperation.

The article explains how a team of medical staff treated (and consequently killed) a number of patients following the flooding of a hospital in New Orleans. The staff in question overdosed the patients to put them out of their pain as they saved other patients who were more likely to survive. The article calls into question the process of triage and how we go about it. Who has the authority to make these decisions, and what lines do we draw between ethics and compassion. The article provides a play-by-play of the events leading up to the flooding, and relevant policies that existed and have been created related to this incident.

The author seems to rely strongly on personal experience and belief to make broad statements about the situation following chernobyl. Most of the article is about the author and their experience with the issue, rather than the objective data and observations of others. This makes the arguments seem rather close-minded and almost biased.
