If you have an employee who is traveling overseas, whether for business or pleasure, be sure to have him or her contact a travel medicine professional. Travelers should up to date on their vaccinations (Hep A, Tetanus, etc.).  Check with the destination region for vaccinations and medications that may be recommended or required to enter a specific country. Another good rule of thumb is don't drink the water even while brushing your teeth, taking a shower, or from the melting ice cubes in your drink. Waterborne illness is the most common cause of sickness and inconvenience among travelers.
