[/INST] Thanks for asking in Chat Doctor forum In short: There are many reasons for recurring fever, one of them is malariaExplanation: As I said there are many reasons for repeated fever/prolonged fever, one of them is malaria. So any doctor has to rule our all the diseases which can cause prolonged fever with battery of investigations before diagnosing properly.
