[Rickettsioses: the epidemiological assessment]
Abstract:
Microbe of taxonomical families Rickettsiaceae aceal and Bartonellaceae of Rickettsiales order have caused not less than 14 nosological forms of disease among people in different parts of the world. About 8 of them--in Russia and in the former Soviet Republics. These diseases are not unequivocal from epidemiological point of view. Trench, Marseilles and other forms of fever, murine typhus, vesicules rickettsia, etc. have been liquidated and never recurred for 30-40 years. Prowazek's [correction of Provachek's] rickettsia in its two forms has lost its epidemiological meaning in Russia and is next to full disappearance. However, some types of fever still represent a definite threat to public health. Some diseases, like ehrlichiosis, Bartonella, tsutsugamushi fever have not yet been studied to the end in Russia.
Insights
Rickettsiales order microbes cause 14 human diseases globally, with 8 in Russia. While some rickettsial diseases are eradicated, others like ehrlichiosis and Bartonella remain a public health concern.
Area of Science:
- Microbiology
- Epidemiology
- Infectious Diseases
Context:
- Microbes from Rickettsiaceae and Bartonellaceae families within the Rickettsiales order are responsible for numerous human diseases worldwide.
- Approximately eight distinct nosological forms of these diseases are documented in Russia and former Soviet republics.
- The epidemiological landscape of these rickettsial diseases has historically varied significantly across regions.
Purpose:
- To review the global and regional impact of Rickettsiales order microbes on human health.
- To highlight the historical eradication and current status of specific rickettsial diseases.
- To identify emerging or understudied rickettsial diseases in Russia.
Summary:
- Rickettsiales order microbes have caused at least 14 distinct human diseases globally, with a significant burden in Russia and former Soviet republics.
- Historically, diseases such as trench fever, Marseilles fever, murine typhus, and rickettsialpox have been successfully controlled and eliminated for decades.
- While some rickettsial infections have diminished in epidemiological significance, others like ehrlichiosis, Bartonella, and tsutsugamushi fever require further investigation in Russia due to ongoing public health relevance.
Impact:
- Provides a historical overview of rickettsial disease epidemiology, noting successful public health interventions.
- Identifies specific rickettsial diseases that have been eradicated or significantly reduced in prevalence.
- Emphasizes the continued threat posed by certain rickettsial infections and the need for further research into understudied diseases like ehrlichiosis and Bartonella in Russia.
