American Trypanosomiasis

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...

Toxoplasmosis

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Giardiasis

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...

Trichomoniasis

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

Summary

Ascariasis is a common parasitic infection in Russia, particularly among children. Despite an overall decrease, its prevalence varies regionally, influenced by both natural and socioeconomic factors, indicating a rising trend.

Area of Science:

Epidemiology
Public Health
Parasitology

Background:

Ascariasis is the most prevalent geohelminthiasis in the Russian Federation, disproportionately affecting children.
While overall incidence has decreased, significant regional disparities in ascariasis prevalence persist across Russia.
Natural background and socioeconomic factors increasingly influence ascariasis distribution and incidence.

Purpose of the Study:

To analyze the epidemiological trends of ascariasis in the Russian Federation from 1991 to 2004.
To identify and map regions with high ascariasis incidence based on natural and socioeconomic factors.
To understand the evolving impact of socioeconomic elements on ascariasis transmission.

Main Methods:

Analysis of incidence rates of ascariasis across 33 and 48 subjects of the Russian Federation.

Epidemiological districting of Russia for ascariasis, considering natural background and socioeconomic variables.

Assessment of trends in ascariasis incidence over a 15-year period (1991-2004).

Main Results:

Ascariasis incidence decreased from 79.5 to 46.0 per 100,000 population between 1991 and 2004.
33 subjects reported incidence rates higher than the Russian average, with 27 located in naturally favorable areas.
Socioeconomic factors like migration and contaminated produce significantly contribute to ascariasis spread, including in northern regions.

Conclusions:

Ascariasis distribution is uneven, with a notable increase in its affected area.
Socioeconomic factors play a crucial role in the current epidemiology of ascariasis.
Continuous monitoring and intervention by public health bodies are essential for ascariasis control and prevention in all Russian Federation subjects.
