Final answer:
Shay should receive the recommended antibiotic treatment for Salmonella Typhi and take precautions to prevent spreading the infection. Rehydration therapy is also essential to prevent dehydration-related complications.
Step-by-step explanation:
Shay has been diagnosed with Salmonella Typhi, which causes typhoid fever, a serious infection characterized by high fever, body aches, headache, and nausea. The illness can become severe, leading to complications like intestinal hemorrhage and dehydration. To combat this bacterial infection, Shay should be treated with the recommended antibiotic treatment such as fluoroquinolones, ceftriaxone, or azithromycin. It is also crucial for Shay to take precautions to prevent the spread of the infection to others, as Salmonella Typhi is contagious and can be asymptomatic in some carriers. Additionally, rehydration therapy may be necessary to prevent complications from dehydration. Vaccination is available and recommended for prevention, especially for those traveling to areas where typhoid fever is common.
