Tips Can Help Residents Avoid Health Problems from Naturally Occurring Bacteria
As summer approaches, Calvert County residents look forward to the recreational opportunities and seafood delicacies afforded by our local waterways. The Calvert County Health Department reminds residents also to be aware of the potential hazards, including the common Vibrio bacteria.
Vibrio, a species of bacteria, are natural inhabitants of sea water. They are found normally in brackish coastal waters such as the Chesapeake Bay and its tributaries. The presence of Vibrio increases in the summer as the water temperature increases and the weather becomes hot and dry. Vibrio can cause gastrointestinal illness if ingested and if an open wound is exposed.
From 2006 to 2010, Calvert County reported 10 cases of Vibrio infection out of 168 cases statewide. In calendar year 2010, Calvert reported four cases, three of which were wound infections.
Most Vibrio infections cause gastrointestinal illness and are associated with the consumption of raw shellfish. Symptoms occur within 24 to 48 hours of ingestion and may include sudden chills, fever, nausea, vomiting or diarrhea. However, death can result in high-risk individuals with weakened immune systems.
Vibrio can also cause severe skin infection if an open wound is exposed while swimming, wading, fishing or crabbing. All open skin areas should be evaluated by a health care provider if showing signs and symptoms of infection such as redness, soreness, swelling or drainage after water contact. Vibrio infections can be treated successfully with antibiotics if identified early.
