After Your Return
Just because you have made it home doesn’t mean you are out of the woods! Especially if you are not feeling too well. The commonest problems in returning travellers include diarrhea, and variations thereof, fever and skin rashes. By far the most concerning symptom in any traveller is a fever.
So, if you have a fever, or in fact any other unwanted problems on your return, or have been exposed to everything under the sun, you should visit your family doctor or a travel medicine specialist.
Fever in a returning traveller is a medical emergency.
Fever in a returning traveller is malaria until proven otherwise.
