Which of the following is a symptom of typhoid fever?

High fever is a hallmark symptom of typhoid fever, which is caused by the bacterium Salmonella typhi. The fever typically rises gradually and can persist for a prolonged period, reaching temperatures as high as 104°F (40°C). This symptom is part of the systemic illness that characterizes typhoid fever, which often also includes abdominal pain, weakness, and potentially other gastrointestinal symptoms.

In contrast, while vomiting, skin rash, and jaundice may be associated with other illnesses or conditions, they are not specific or typical symptoms of typhoid fever. For example, vomiting is more commonly seen in gastrointestinal infections, skin rashes can result from various pathogens and allergic reactions, and jaundice specifically indicates liver dysfunction or disease but does not directly relate to typhoid fever. Thus, high fever stands out as a distinctive and defining symptom for typhoid fever, emphasizing the severity of this infection.
