Eleanor (88) is enjoying her stay at an all-inclusive resort for seniors in northern Australia when she starts experiencing symptoms of cough, shortness of breath, fever, muscle aches, and a persistent headache. She is negative for COVID-19, Strep throat, and Influenza, but chest X-ray and sputum analysis indicate a sever Gram-negative bacterial infection. Tetracycline is prescribed, but Eleanor’s condition worsens. Robert (91), Clara (75), James (82), and Samuel (81) also become ill and are admitted to the resort’s medical facility two days later. All six patients, including Eleanor, have been participating in resort activities like hiking and swimming, as well as sharing common areas. The resort management contacts a medical team to investigate the outbreak and gather information on patient histories, food consumption, and the resort’s water supply and maintenance protocols. After analysis, the team identified the infection as Burkholderia pseudomallei, a noncommunicable bacterial pathogen commonly found in soil and water in tropical regions. It can be transmitted through direct contact with contaminated soil or water, or by inhalation. The infection is known as melioidosis and can cause severe pneumonia and other systemic infections. A synergistic therapy of amoxicillin-clavulanic acid and Sulfamethoxazole-trimethoprim is prescribed to all six patients. The nursing home is instructed to improve soil and water management practices, including limiting access to high-risk areas, increasing drainage, heating water above 50degrees C, installing membrane filtration, and adding chlorine to sterilize/disinfect all potentially contaminated water sources. All staff and residents are also instructed to wear face masks temporarily. 1. List and describe the five stages of disease in order. When would the patients be the most contagious? Why?
