Vibriosis

About This Disease

Vibriosis is an illness caused by bacteria in the same family that cause Cholera. Large outbreaks have been associated with Cholera, however Vibriosis has been associated with sporadic reports and few outbreaks and septicemia. Countries reporting sporadic cases and outbreaks are Japan, Southeast Asia, and United States.

  • Abdominal cramps
  • Nausea, vomiting, fever, chills, and headache
  • Symptoms usually appear 12–24 hours after eating contaminated seafood

Transmission

You can get vibriosis by eating raw, undercooked fish or shellfish taken from contaminated coastal waters. You can also get vibriosis from any food cross-contaminated with raw seafood, or by rinsing foods with contaminated seawater. Also, when you have open cuts or wounds and exposed to contaminated seawater. Vibriosis is not passed person to person.

 

Treatment

Severe diarrhea and/or vomiting over a long time may cause the body to lose fluid too quickly. Lost fluids should be replaced by drinking liquids such as fruit juices, soups, and special fluids called oral rehydration salts. If you become hospitalized, sometimes fluids can be replaced through the veins. A doctor may also treat with medicines to shorted the period of diarrhea and passing the bacteria in the stool.

Immunity

There is no immunity to Vibriosis. Persons may become infected more than once.
