The health situation in the Yemeni port city of Hudaydah is the worst in the country and risks to civilians increase every day as the conflict intensifies, the World Health Organisation (WHO) said.
The UN body said in a statement published on its website on Sunday that the number of people who need humanitarian assistance in the city has increased.
"Today, the governorates of Hudaydah province record the largest number of cholera cases and the highest rates of malnutrition in Yemen," it said.
The statement quoted WHO representative in Yemen, Dr Nevio Zagaria as saying that the situation in the city of Hudaydah is getting worse every day and the reality on the ground is bleaker.
"We need to ensure that the most needy have access to services, especially mothers, children and patients suffering from chronic diseases such as diabetes and high blood pressure," he said.
Zagaria warned that Yemen's health system was too fragile, so any additional burden could disrupt existing capabilities.
According to the statement, the organisation currently supports two hospitals in the city as well as seven therapeutic feeding centres to treat severely malnourished children who have medical complications.
The statement pointed out that the WHO previously stockpiled medicines and various medical supplies.
The Yemeni government forces backed by the Arab coalition launched on 13 June a military operation to retake the strategic city of Hudaydah from Houthi fighters.
