Epidemiology and Infection
|June 16, 2010
Summary
Vibriosis cases in Florida increased due to wound infections, not just oysters. Underlying health conditions significantly raise the risk of death from Vibrio infections.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Vibriosis, caused by Vibrio bacteria, is a significant public health concern.
- Understanding the epidemiology of Vibrio infections is crucial for effective prevention and control.
- Florida has historically reported cases of vibriosis, necessitating updated epidemiological data.
Purpose of the Study:
- To characterize the epidemiology of Vibrio infections in Florida from 1998 to 2007.
- To identify common Vibrio species, exposure sources, and clinical syndromes.
- To determine risk factors for mortality associated with Vibrio infections.
Main Methods:
- Retrospective analysis of Vibrio infection cases reported in Florida between 1998 and 2007.
- Logistic regression modeling to assess the risk of death.
- Data analysis included species identification, exposure routes, clinical presentations, and patient health conditions.
Main Results:
- 834 Vibrio infections were reported in 825 individuals, with an average annual incidence rate of 4.8 per 1,000,000.
- The most common species were Vibrio vulnificus (33%), V. parahaemolyticus (29%), and V. alginolyticus (16%).
- Wound infections (45%) and gastroenteritis (42%) were the most frequent clinical syndromes, with wounds being the primary exposure source (42%).
- Nearly half of the infected individuals had underlying health conditions, which were significantly associated with an increased risk of death.
- While Vibrio infections linked to raw oyster consumption decreased, those associated with wound infections increased.
Conclusions:
- Vibriosis epidemiology in Florida has shifted, with a notable rise in wound-related infections.
- Underlying health conditions are critical determinants of mortality in Vibrio infections.
- Prevention strategies should expand beyond oyster consumption advisories to include education on wound-related risks, particularly for vulnerable populations.

01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:22Botulism
Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
01:28Infectious Diseases and Their Occurrence
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
01:12Giardiasis
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...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
