Advice for Travellers

Malaria is a potentially serious infection transmitted to humans by mosquito bites. It is not usually transmitted in Maryland or anywhere else in the USA. The risk is very low at this time.

If you are travelling to Maryland, you should:

• understand your risk of malaria
• know how to protect yourself against mosquito bites at all times during your trip, to help prevent malaria and other mosquito-borne infections
• where possible, reduce the number of mosquitoes in and around your accommodation.

If you develop a high temperature (fever) during your trip, or after you return home from an area where malaria is a risk, seek medical advice as soon as possible and tell the doctor about your recent travel history.
