Stay safe & healthy
Tourists are usually welcomed warmly in Rwanda, and the country is largely considered safe for visitors. The possible exceptions are certain places along the Congolese and Burundian borders. Rwandan troops rumoured to be involved in the civil war that still plagues the northeast of Democratic Republic of the Congo, mainly due to the presence of Interhamwe who fled after the 1994 genocide. Gisenyi and Kibuye are considered safe, but the border situation can change at any time: check Foreign Office information and local sources for further advice.
Gorilla trekking near to the DRC border is generally considered safe, due to the large and continuous Rwandan army presence.
While travelling in matutus (taxis) in the countryside, don't be surprised if the matutu drives through several police/military check-points. This is done to check IDs, car registration and insurance, so it would be wise to bring at least a photocopy of passport with you everywhere you go in Rwanda.
The following is an excerpt from the US State Department's Consular Information Sheet on Rwanda updated on 1 Dec 2006:
Medical and dental facilities are limited, and some medicines are in short supply or unavailable. Travellers should bring their own supplies of prescription drugs and preventive medicines. In Kigali, Americans may go to King Faycal Hospital, a private facility that offers limited services. There is also a missionary dental clinic in Kigali staffed by an American dentist. An American-operated missionary hospital with some surgical facilities is in Kibagora, in southwestern Rwanda. Another hospital with American physicians is in Ruhengeri, near the gorilla trekking area, and a Chinese hospital is in southeastern Rwanda in Kibungo. There is also a very good hospital near Lac Muhazi, where even people from Kigali go to. The US Embassy maintains a current list of healthcare providers and facilities in Rwanda. This list is included in the Consular Section’s welcome packets for American citizens. There are periodic outbreaks of meningitis in Rwanda. Yellow fever can cause serious medical problems, but the vaccine, required for entry, is very effective in preventing the disease. HIV/AIDS is high among adults at 9% or 1 in 11. Practice safe sex. Avoid intravenous drug use.
