From ABC News:

Despite easing the blockade on some humanitarian aid, commercial chips have been unable to access the country leaving the country without much needed supplies. Health and water facilities cannot operate with the fuel these ships would bring.

“Urban water networks in seven cities have run out of fuel and now depend on humanitarian organizations to fill in the gap,” the officials said. “Other cities will shortly be in a similar situation if the blockade is not lifted, which would leave 11 million people without safe water.”

The lack of fuel would lead to a “new crisis” that would compound other issues, like lack of access to clean water, UNICEF’s representative in Yemen, Meritxell Relano, told ABC News. The average price of diesel in Yemen has risen 99 percent since September, and the average price of petrol had gone up 71 percent in that period, she said last week.

“The ports need to be open so the commercial goods can come in and the markets can be activated,” Relano said. “The people cannot exist alone on food aid.”

In some areas, the price of trucked-in water has jumped 600 percent, the price of wheat flour had gone up 30 percent, and the price of wheat flour had risen 30 percent, the UN and aid officials said in their statement Saturday, without giving a timeframe.

Without fuel and water, more hospitals and health center will shut down — less than half are currently operating — and six cities’ sewage networks have already been compromised, the officials said.

According to Reuters, the lack of fuel could create a resurgence of cholera.

Some 960,000 suspected cases of cholera and 2,219 deaths have been reported since the epidemic began in April, WHO figures show.

Children account for nearly a third of infections of the waterborne disease, spread by food or water contaminated with human feces, that causes acute diarrhoea and dehydration and can kill within hours if untreated.

Although the number of new cases has dropped for 11 straight weeks, 35 districts in Yemen are still reporting cholera with “high attack rates” in communities, Zagaria said.

A deteriorating economic situation and lack of safe drinking water, due to water sewage systems in many cities lacking fuel for the pumps, have compounded the humanitarian crisis, he said.

“This is a perfect mix to have a new explosion of a cholera epidemic at the beginning of the rainy season in March of next year,” Zagaria said in a telephone interview from Sanaa, amid four days of clashes in the capital city.
