The Pew Charitable Trusts

In March, nearly 40 individuals from across the country will meet with their legislators to urge Congress to take bipartisan action to prioritize the battle against antibiotic resistance: a looming global health threat that threatens the future of modern medicine. As part of The Pew Charitable Trusts’ Stand Up to Superbugs initiative, this year’s ambassadors include health care professionals, public health officials, scientists, farmers and ranchers, veterinarians, superbug survivors, and people who have lost loved ones to an antibiotic-resistant infection. They will meet virtually with federal agency leaders and members of Congress to share their superbug stories and expertise, and urge increased commitment and momentum to preserve the effectiveness of existing antibiotics and develop urgently needed new ones.

Joanna Sandager

In 2007, Joanna Sandager’s, B.S.N., R.N., family packed the car and drove her to the College of William & Mary to start her freshman year. But a few weeks after school started, an antibiotic-resistant staph infection put all that in jeopardy. Sandager contracted MRSA in a small cut in her leg. Her mother had recently seen a news broadcast about MRSA outbreaks in Virginia and urged her daughter to go to the emergency room. Thanks to her mom’s quick thinking, Sandager was promptly admitted to the hospital and treated with vancomycin. The infection had spread so fast that for a few days doctors considered amputating her leg. Fortunately, her treatment was successful without amputation, but the rest of her first year away from her family was spent in and out of the hospital and student health center receiving intravenous antibiotics as the infection recurred.

Sandager is a recent graduate of Virginia Commonwealth University’s School of Nursing and works as a registered nurse in Norfolk, Virginia. She feels lucky that the antibiotics available 10 years ago were successful in treating the infection, but worries about the future for her patients. She is passionate about preserving the antibiotics we have and encouraging lawmakers to protect and expand funding to spur the development of new drugs to tackle the superbugs we will face in the next decade.
