I don't get this statement. "Most cases (of typhoid fever) in developed countries are imported from endemic countries."
Most cases come from countries where typhoid fever occurs a lot.

How can I put this sentence into my own words?
"Use scupuluous cleanliness in food preparation and handling."
Use a synonym for "scrupulous."
The statement "Most cases (of typhoid fever) in developed countries are imported from endemic countries" means that the majority of typhoid fever cases in developed countries come from people who have been infected with the disease while they were in countries where typhoid fever is common, known as endemic countries.
Now, let me explain how to understand this statement.
First, we need to understand what "typhoid fever" is. Typhoid fever is a bacterial infection caused by a bacteria called Salmonella enterica serotype Typhi. It is usually spread through contaminated food or water and is more common in areas with poor sanitation and limited access to clean water.
Next, we should understand what the term "endemic countries" means. Endemic refers to a disease that is regularly found in a specific geographic area. In the case of typhoid fever, endemic countries are those where the disease is prevalent.
So, when the statement says "Most cases (of typhoid fever) in developed countries are imported from endemic countries," it means that the majority of typhoid fever cases in developed countries occur in people who have contracted the disease while traveling or living in countries where typhoid fever is common. These individuals then bring the infection back to their home countries.
To understand this statement better, we can consider the reasons behind it. Developed countries generally have better sanitation systems, access to clean water, and adequate healthcare facilities, which help prevent typhoid fever. However, when people from developed countries travel to endemic countries where the disease is more prevalent, they may be exposed to contaminated food or water sources, increasing their chances of getting infected. When they return to their home country, they may continue to exhibit symptoms and seek medical help, leading to diagnosed cases of typhoid fever in the developed country.
Overall, the statement highlights the fact that the main source of typhoid fever cases in developed countries is through individuals who acquire the infection while in countries where the disease is endemic.
