No, Ebola has been a problem in West Africa, but not in East Africa, including Tanzania. Temperatures are taken at the border and points of entry to filter out passengers who may have any sort of transmittable infection. While there are still some cases of malaria, the majority are in remote rural areas where tourists normally do not travel. Most lodges and hotels have limited risks of mosquitoes and every facility we partner with provides nets around beds at night. Tanzania is a very safe country to visit in all respects.
