Term Analysis

On the base of long-term analysis ofprevalence of the hemorrhagic fever with renal syndrome (HFRS) and data of hantavirus infections in Apodemus mice - reservoirs ofpathogenic hantaviruses, the relation between of spatio-temporal peculiarities of prevalence of HFRS in Primorye Territory with activity of epizootic process in rodent populations during different phases of their population cycles has been established.

The Relationship

A study was made of the specific features of the incidence of hemorrhagic fever with renal syndrome among military personnel in the territory of Primorsky Krai and the relationship between the manifestations of infection and the epizootic process among natural carriers of hantavirus. It was established that the incidence of this infection from 2001 to 2015 was characterized by a predominance of middle-aged persons, a connection between the severity of the clinical course and infection conditions, a seasonal and long-term distribution of cases and features of the epizootic process among murine rodents - natural carriers of hantavirus. Infection with ortho-hantavirus among military personnel took place both in domestic conditions and in the process of military professional activity. The circumstances of the most frequent occurrence of sporadic and group cases of diseases are revealed.

Abstract. The use of documentary evidence to investigate past climatic trends and events has become a recognised approach in recent decades. This contribution presents the state of the art in its application to droughts. The range of documentary evidence is very wide, including general annals, chronicles, memoirs and diaries kept by missionaries, travellers and those specifically interested in the weather; records kept by administrators tasked with keeping accounts and other financial and economic records; legal-administrative evidence; religious sources; letters; songs; newspapers and journals; pictographic evidence; chronograms; epigraphic evidence; early instrumental observations; society commentaries; and compilations and books. These are available from many parts of the world. This variety of documentary information is evaluated with respect to the reconstruction of hydroclimatic conditions (precipitation, drought frequency and drought indices). Documentary-based drought reconstructions are then addressed in terms of long-term spatio-temporal fluctuations, major drought events, relationships with external forcing and large-scale climate drivers, socio-economic impacts and human responses. Documentary-based drought series are also considered from the viewpoint of spatio-temporal variability for certain continents, and their employment together with hydroclimate reconstructions from other proxies (in particular tree rings) is discussed. Finally, conclusions are drawn, and challenges for the future use of documentary evidence in the study of droughts are presented.

Plague, caused by Yersinia pestis infection, continues to threaten low- and middle-income countries throughout the world. The complex interactions between rodents and fleas with their respective environments challenge our understanding of human plague epidemiology. Historical long-term datasets of reported plague cases offer a unique opportunity to elucidate the effects of climate on plague outbreaks in detail. Here, we analyse monthly plague deaths and climate data from 25 provinces in British India from 1898 to 1949 to generate insights into the influence of temperature, rainfall and humidity on the occurrence, severity and timing of plague outbreaks. We find that moderate relative humidity levels of between 60% and 80% were strongly associated with outbreaks. Using wavelet analysis, we determine that the nationwide spread of plague was driven by changes in humidity, where, on average, a one-month delay in the onset of rising humidity translated into a one-month delay in the timing of plague outbreaks. This work can inform modern spatio-temporal predictive models for the disease and aid in the development of early-warning strategies for the deployment of prophylactic treatments and other control measures.
