82 percent of the population in Yemen's western province of Taiz suffered from Dengue Fever, showed a recent survey.
The Republican Hospital's Labs concluded the percentage from randomly surveying 400 samples and data from three hospitals in the province.
The survey comes as the disease continued to claim lives, with a few deaths reported in most recent days.
Local sources said that a hospital director died from the disease, reported two months ago but no effective action has been taken to prevent its outbreak, after doctors at the Al-Esra'a Hospital could not help him.
Last week, a young man was reported dead from the fever and dozens of the people infected in the district of Bajil.
The authorities have been blamed by the people in the province, who claimed they alerted them but have seen inaction to tackle this terrifying disease.
Some people also died in neighboring Ibb province after they were infected with it.
Since the disease started two months ago, dozens of the people were reported infected and some dead.
Hundreds of animals died as also.
