Dengue fever
There is no vaccine that works to keep people from getting the dengue virus. There are a few things that can be done to prevent people from getting dengue fever. People can protect themselves against mosquitoes and limit the number of bites they get. Scientists also suggest making mosquito habitats smaller and reducing the number of mosquitoes that exist. Once a person has dengue fever, he usually can recover just by drinking enough fluids, as long as his disease is mild or moderate.
