The head of the World Health Organization has arrived in Congo's capital, Kinshasa, to support efforts against an Ebola outbreak. Medical personnel are struggling with equipment shortages, distrustful populations and armed groups. WHO Director-General Tedros Adhanom Ghebreyesus emphasized community collaboration. The outbreak of a rare type of Ebola is spreading faster than the response, with 906 suspected cases and 223 deaths. Aid from the EU and the U.S. is arriving. Health workers face challenges due to local burial rites and regional conflicts. The WHO is discouraging travel bans, but the U.S. has imposed a 21-day ban on noncitizens who have visited Congo and two neighboring countries.
