You MUST take out travel/medical insurance for your trip and it’s up to you to arrange this and to ensure you are adequately covered.
Check firstly with your University and see if they offer cover for your trip.
Depending on your project you will usually need cover for veterinary work, needle stick and working with wildlife.
There are many different companies who offer insurance and whilst we cannot give advice or recommend any particular company, here are a couple of links to different companies that you may wish to look at.
**We are in the process of creating the different insurance links which will put you directly in contact with the insurance companies. If you have any questions please contact me at email@example.com
