Final answer:
In the absence of antibiotics, rehydration therapy is highly effective in treating Cholera by replenishing lost fluids and electrolytes. Antibiotics are only necessary for severe or disseminated cases of Cholera.
Step-by-step explanation:
In the absence of antibiotics, rehydration therapy is highly effective in treating Cholera. Cholera is a bacterial infection caused by Vibrio cholerae, which releases a toxin that leads to profuse diarrhea and dehydration. Rehydration therapy replenishes lost fluids and electrolytes, improving the patient's condition while the infection resolves. It is the primary treatment for Cholera, and antibiotics are only necessary for severe or disseminated cases.
