Stay safe & healthy
Cyclones possible during rainy season (December to April).
Le Kartala on Grand Comore is an active volcano.
Civil war possible; Anjouan island most at risk (clashes between rebel and African Union forces).
Malaria, including cerebral malaria, is prevalent in the Comoros. Sleep under a permethrin-treated mosquito net and take an anti-malarial. Grand Comore and Anjouan have the best medical infrastructure and you can be tested for malaria in most major towns. If you get a fever, it is wise to get tested, especially if the fever does not respond to paracetamol or does not go away. Moheli has a hospital in Fomboni and one that recently re-opened in Nioumachoua but may occasionally be accessible.
Healthy food is not difficult to find. Eat many fruits and vegetables as well as rice. During some time of the year vegetables might be only available in small quantities in Moheli. A healthy and delicious local dish is madaba; pounded and boiled manioc leaves. But madaba takes hours to prepare, so you may not find it in restaurants. If you are fortunate enough to stay or eat with a local family, you might get to try madaba. Vegetarians should be aware that on Grand Comore locals put fish in the madaba, while on Moheli they do not. Women may experience cessation or alteration of their menstrual cycle due to poor nutrition if they stay in the Comoros for several months or longer.
