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.

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...

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...

Background:

Cat scratch disease (CSD) is a zoonotic infection caused by Bartonella henselae.
CSD affects an estimated 12,500 individuals annually in the US.
Limited data exists on US clinician experience and management of CSD.

Purpose of the Study:

To assess the clinical burden of CSD in the US.
To evaluate primary care provider (PCP) knowledge and practices regarding CSD treatment and prevention.
To identify potential gaps in CSD education for PCPs.

Main Methods:

A survey of 3,011 US primary care providers (family practitioners, internists, pediatricians, nurse practitioners) was conducted in 2014-2015.
The survey assessed clinician experience, diagnosis rates, treatment choices, and prevention strategies for CSD.
Data was analyzed to identify trends in CSD diagnosis and management among different regions and specialties.

Main Results:

37.2% of surveyed clinicians diagnosed at least one CSD case in the prior year.
Clinicians in the Pacific and Southern regions, and those seeing pediatric patients, were more likely to diagnose CSD.
Significant deviations from recommended treatment guidelines were observed, with 71.4% choosing antibiotics over monitoring for uncomplicated CSD.

Conclusions:

A substantial number of US primary care providers encounter CSD cases annually.
Current clinical practices indicate knowledge gaps in the recommended treatment and prevention of CSD.
Targeted educational initiatives are needed to improve PCP management of CSD and Bartonella henselae infections.
