A hospital for tropical diseases is a special type of hospital that helps people who are sick with illnesses that are mostly found in warm places, like the tropics.
Imagine going on a vacation to a far-off place with lots of sunshine and beaches. While you're there, you could get bitten by bugs, like mosquitoes, or be around animals that carry diseases. These diseases can be very different from what we see in regular hospitals, so special doctors, called tropical medicine specialists, work at tropical hospitals.
These doctors learn how to identify the strange diseases that are caused by bacteria, viruses, and parasites that we don't usually see in our own countries. They also know which medicines work best to treat these diseases.
If you get sick with a disease from a tropical place, you might have to go to a hospital for tropical diseases. Here, you will be taken care of by people who know exactly what's wrong with you and how to make you feel better. They might give you medicine, special food, and lots of rest to make the sickness go away.
So, in summary, a hospital for tropical diseases is a special hospital that helps people who are sick with illnesses that are mostly found in warm places and has doctors who know how to treat them with the right medicine and care.
