· Remember that mountain gorillas are very susceptible to human diseases. The following rules are ways to minimize the risk your visit might poses to them:

· Respect the limits imposed on the number of visitors allowed with the gorillas each day. This minimizes the risk of disease transmission and stress to the group.

· If you are feeling ill, or you are carrying a contagious disease, volunteer to stay behind. An alternate visit will be arranged for you, or you will be refunded your money.

· If you feel the urge to cough or sneeze when you are near the gorillas, please turn your head away and cover your nose and mouth in order to minimize the spread of bacteria or viruses.

· Always stay 7 meters (21 feet) away from the gorillas. This is to protect them from catching human diseases.

· Do not leave any rubbish (e.g. food wrappers) in the park; foreign items can harbor diseases or other contaminants.

· If you need to go to the toilet while in the forest, please ask the guide to dig you a hole with his panga. Make sure the hole is 30 cm deep and fill it in when you are finished.
