Malaria ?!?!

hi!!! my boyfriend and i have been travelling in SEA and he’s been getting this nasty recurring flu-like thing that we’re starting to worry about.
fever, chills, diarrhoea, sharp stomach cramps, dizziness and general weakness. anybody know a good doctor in taipei that could treat him and test for malaria or other possible illnesses? we don’t have health coverage right now so hopefully it could be done in one visit. thanks a lot!
