Answer: B

Reference: uptodate Basic advice for travelers to moderate or high-risk regions for travelers' diarrhea includes eating only food that has been thoroughly cooked and served hot, fruits that the traveler peels just prior to eating, and pasteurized dairy products. Beverages should be bottled or disinfected. Bottled drinks should be requested without ice and should be drunk from the bottle with a straw rather than from a glass. Hot tea and coffee are usually safe alternatives to boiled water.” “Although antibiotics and other agents (namely bismuth salicylate) are effective in reducing the rate of travelers' diarrhea for individuals traveling from resource-rich to resource-poor areas, we do not routinely recommend chemoprophylaxis. Use of daily antibiotics is expensive, has potential side effects, can wipe out normal gastrointestinal flora that may be beneficial, and can promote bacterial resistance.” “However, chemoprophylaxis may be a reasonable approach in the setting of an underlying medical con- dition that would increase the risk of complications from diarrhea or would be severely exacerbated by dehydration from diarrhea such that the benefits of using antibiotic prophylaxis outweigh its risks. Such situations include known severe inflammatory bowel disease that could be exacerbated by an episode of infectious diarrhea; severe vascular, cardiac, or renal disease that would be seriously compromised by dehydration; or a severe immunocompromised state, such as advanced HIV disease or after a complicated organ transplant
