Zoonotic Semiotics: Plague Narratives and Vanishing Signs in Madagascar.

Zoonosis calls for a multispecies approach to medical semiotics, a method involving the decipherment of outward symptoms and the construction of narrative. In Madagascar, early detection of bubonic plague outbreaks relies on sightings of sick and dead rats. However, people most vulnerable to plague often do not perceive warning signs, and plague symptoms do not always present in rat and human bodies. In August 2015, a plague outbreak killed 10 residents of a rural hamlet in the central highlands. To reconstruct the transmission chain, scientists elicited survivors' memories of dead rats in the vicinity. Not only were these clues imperceptible to most, but residents had also constructed an alternative outbreak narrative based on different evidence. Stark health disparities, a lack of historical memory of the plague, and genetic adaptations of rats and plague bacteria have created a problem of "semiotic cluelessness" that complicates outbreak control measures and increases mortality.

Plague Masks: The Visual Emergence of Anti-Epidemic Personal Protection Equipment.

Often described as "masks" face-worn devices are employed as personal protection equipment by health workers and the general public and considered to be an indispensable technology against epidemics. Simultaneously, they are potent symbols of existential risk. Could these material and visual aspects be more than simply indexically connected? In this article, I examine these apparatuses through a historical anthropological approach of their invention during the 1910-11 Manchurian plague outbreak. Arguing that they should be taken seriously as masks, I demonstrate that their emergence was rooted in their configuration as transformative agents of medical reason.

Ethnohistory and the Dead: Cultures of Colonial Epidemiology.

What were the dead to colonial epidemiologists? Doctors and colonial scientists involved in the response to epidemics of plague in Madagascar in the first half of the twentieth century speculated about the role of Malagasy mortuary ritual in the spread of plague, and sought to bring Malagasy ritual into line with Pasteurian hygienic norms. I examine confrontations over death and the management of the dead in Madagascar, tracing the textured form of epidemiological knowledge that arose from the confrontation between Malagasy cosmology and Pasteurian counter epidemic technique.

The plague under Commodus as an unintended consequence of Roman grain market regulation.

This paper begins with a review of Roman grain market policies. It is argued that policies such as forced sales and maximum prices made urban consumers hesitant to rely on the market for secure access to grain. Consequently, consumers hoarded grain in their homes. The hoarded grain formed a volatile fuel ready to be ignited by the arrival of the bubonic plague bacillus. This scenario fits events in the city of Rome under Commodus. Attested grain market interventions were followed by a severe epidemic, arguably bubonic plague, which decimated the city's population.

Shutt up: bubonic plague and quarantine in early modern England.

The outbreak of bubonic plague that struck London and Westminster in 1636 provoked the usual frenzied response to epidemics, including popular flight and government-mandated quarantine. The government asserted that plague control measures were acts of public health for the benefit of all. However, contrary to this government narrative of disease prevention there was a popular account that portrayed quarantine and isolation as personal punishment rather than prudent policy. In examining the 1636 outbreak on the parish as well as the individual level, reasons for this inconsistency between official and unofficial perspectives emerge. Quarantine and its effects were not classless, and its implementation was not always strictly in the name of public health. Government application of quarantine was remarkably effective, but it could never be uncontroversial both because of circumstances and because of misuse. The flight of the wealthiest from London and Westminster left only the more socially vulnerable to be quarantined. Though plague policy was financially sensitive to the poorest, it was costly to the middling sort. Another cause of controversy was the government's use of quarantine as a punishment to control individuals found breaking other laws. Though not widely publicized, popular narratives continually included grievances about the cruelty and inequity of quarantine and the militaristic nature of its implementation. Despite these objections, quarantine remained a staple of the government response to plague outbreaks throughout the seventeenth century.

[The origins of the Pavilion Lazaretto: quarantine architecture between the 18th and 19th centuries]. / Los orígenes del Lazareto Pabellonario: la arquitectura cuarentenaria en el cambio del setecientos al ochocientos.

The model of pavilion lazaretto was built above the scientific basis established during the hospital reform process held in France on the lasts decades of the eighteenth century. The morphological solutions adopted for the new quarantine taxonomy has not been given by the example borrowed by the new typology of hospital as resulted in this discussion, but by existing quarantine and detention facilities in general. In this paper we will analyse all factors that have influenced in the configuration of this model of lazarettos.

The origins of the health defence system against contagious illness: the strategies of isolation and quarantine in Mediterranean cities from the XIV-XIX centuries.

From the onset of the Black Death in 1347-48, Italian cities which faced the Mediterranean, an epidemic sea, constructed a complex and articulated health defence system which was an example to all other western countries. The cornerstones of this health defence system lay in quarantine, sanitary cordons, lazarets, disinfection, and in the social regulation of the population at risk. Medicine played no part. Its impotence in dealing with epidemic diseases left health defence to the initiative of the civil authorities who rigorously fought the repeated incursions of plague, which from the end of Middle Ages severely tried and tested social organisation, economic life and public order, all of which were threatened by reactions of fear and aggression. From the fifteenth century onwards the public authorities instituted health magistracies which perfected policing and hygiene strategies based on isolation, separation and social control. This progressively extended to individuals in the community through 'health certificates'. This paper follows the evolution and crises of the conceptual, cultural adn institutional response to epidemics through the centuries up to the appearance of the plague of cholera and its disappearance.
