deadly threat
These bacteria contain a large arsenal of molecular weapons, including various toxins, which help the bacteria hijack cells, snatch nutrients, destroy structural proteins, tear down tissue linings, leak blood vessels, promote destructive inflammation, suppress immune defenses, and generally wreak havoc on their victims.
overall mortality rate of V. vulnificus Infection is about 35 percent. But for anyone infected who also has a compromised immune system or liver condition, the mortality rate reaches 50-60 percent. Similarly, for people who get sepsis – a life-threatening infection – the mortality rate is also about 50 percent. For patients like the man in this case, if antibiotics or surgical removal of the necrotic tissue is delayed, the mortality rate increases to 100 percent.
In this case, the man did not die. But by the time he reached the hospital, his right leg was so damaged that it had to be amputated above the knee. Meanwhile, his forearm required extensive skin grafting, which was collected from elsewhere on his body. After antibiotic treatment and six months of treatment, doctors reported that he had recovered.
The case highlighted that the threat of V. vulnificus It is only increasing amid climate change, and medical experts see its rise as an urgent public health concern. Warming waters, geographic spread and increasing antibiotic resistance are increasing the risk. US cases between 1998 and 2018 V. vulnificus There has been an eightfold increase, including expansion in areas where the bacteria are considered rare, including Massachusetts, New Hampshire and Maine.
“Abundance and geographic range of V. vulnificus The increase is predicted to be due to factors related to climate change, including increased water temperatures, storm surges, changes in salinity and algal blooms,” the man’s doctors wrote.
The Centers for Disease Control and Prevention advises to avoid Vibrio To avoid infection, eat only thoroughly cooked seafood and wash your hands after touching raw seafood. If your wound is open, avoid going in salt water or at least cover it tightly. If a wound was caused while in salt water or if an existing wound is open, wash it with soap and clean, running water.
