The epidemics spread over Yemeni northern provinces, including Hodeidah, Hajjah, Raymah, Mahweet, Taiz, Ibb and Saada.
"A total of 116,522 confirmed cases of malaria and 23,000 confirmed cases of dengue fever have been recorded since January," the health authorities said in a statement obtained by Xinhua.
The health sector in Yemen has been badly affected by the civil war, which allowed the spread of infectious diseases, including cholera.
World Health Organization said that cholera in Yemen has set the world's record with the infection of over 1 million people, while over 2,000 people have been confirmed dead from the disease since 2017.
Since March 2015, Saudi Arabia and some of its Arab allies, including the UAE, have been carrying out deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive former president Abd Rabbuh Mansour Hadi.
Official UN figures say that more than 15,000 people have been killed in Yemen since the Saudi-led bombing campaign began.
The Saudi-led war has impacted over seven million children in Yemen who now face a serious threat of famine, according to UNICEF figures. Over 6,000 children have either been killed or sustained serious injuries since 2015, UN children’s agency said. The humanitarian situation in the country has also been exacerbated by outbreaks of cholera, polio, and measles.
