Referring to aid agencies, Jens Laerke, spokesman for the UN Office for the Coordination of Humanitarian Affairs (OCHA) told a Geneva briefing: "We hear from many of them that Yemen is really on the brink right now. The situation is extremely alarming, they are talking about that the health system has in effect collapsed."
"They are talking about having to turn people away because they do not have enough (medical) oxygen, they do not have enough personal protective equipment," he said.
Yemen authorities have reported 184 cases including 30 deaths to the World Health Organization (WHO), its latest figures show. "The actual incidence is almost certainly much higher," Laerke said.
The United Nations estimates that it will seek $2 billion for Yemen to maintain aid programmes through year-end, he added.
