Highlights:
Since 26 March, 4.4 million people have received humanitarian assistance.
The national health-care system has reached a breaking point. Dengue fever cases are rising, chronic diseases lack treatment, and vital medical supplies and personnel cannot reach targeted people.
Commercial imports of food, medicine and fuel are at a virtual standstill. Seaports and airports are operating at minimal capacity and road networks are non-functional.
Violence and insecurity continue to weaken already fading protection and social safety nets.
Access constraints remain high. Humanitarians are at great risk, but they continue to deliver assistance.

Situation Overview
Yemen’s health-care system is on the brink of collapse. Cases of fatal dengue fever continue to rise: Aden local authorities reported 8,000 cases (double the number reported two weeks ago) and nearly 590 deaths (five times the number reported two weeks ago). This indicates that in Aden, there is an average of 150 new cases of dengue fever every day, with 11 deaths daily. WHO reports a high risk of a polio outbreak (Yemen has maintained a polio- free status since 2006). Concerns are increasing that fear of diseases such as dengue, measles, rubella and malaria may cause additional displacement. People suffering from chronic life-threatening, non-communicable diseases are also falling prey to the deteriorating health system.
Fuel imports are now at 11 per cent of pre-crisis figures. There is a cereal shortfall of 400,000 MT and Yemeni ports continue to operate at a fraction of pre-crisis capacity. Aden, the largest port, is inaccessible due to insecurity, and there are continued reports that ships carrying humanitarian cargo were not able to berth. The oil refinery in Aden port was attacked on 28 June and the consequences of the fire that ensued are being assessed. Only two out of eight berths in Hudaydah port are operating. The commercial and humanitarian consignment delays at sea are increasing shipping costs, which will lead to increased commodity prices.
The constraints to humanitarian action in Yemen enormous. Lack of diesel means that imported grain cannot be milled and therefore consumed, hospital generators cannot run and the water supply for millions of people is threatened. Roads are too insecure to move goods around the country, and humanitarian partners are at risk and threatened trying to reach people in need. Prior to the escalation of violence, Yemen imported 90 per cent of its food and 80 per cent of its medicine and pharmaceutical supplies.
Over 21 million people require some form of humanitarian assistance. This year humanitarian partners aim to deliver assistance to 11.7 million people. Since 26 March 4.4 million people have received humanitarian assistance. There is an urgent need for unimpeded humanitarian access that protects affected men and women from seeking assistances and humanitarian workers.
