Hello Ann,
As you are travelling to a region where mosquitoes are present we would advise (subject to consultation with a qualified pharmacist or your doctor) you purchase high performance mosquito repellent before your trip and apply this regularly during your holiday, including when you go to bed. We would also suggest that you take with you a ‘plug-in’ mosquito repellent device for your hotel room as an extra measure. These, along with DEET based repellents, are available from most pharmacies.
In terms of taking tablets (or any other medication) I would strongly advise that you speak with your GP who not only has the most up to date information but also (and perhaps most importantly) your medical history.
Kindest regards,
Julia
