Dengue will ‘take off’ in southern Europe, US, Africa this decade, WHO scientist says

Published

Dengue fever will become a major threat in the southern United States, southern Europe and new parts of Africa this decade, the WHO's chief scientist said, as warmer temperatures create the conditions for the mosquitoes carrying the infection to spread.

The illness has long been a scourge in much of Asia and Latin America, causing an estimated 20,000 deaths each year. Rates of the disease have already risen eight-fold globally since 2000, driven largely by climate change as well as the increased movement of people and urbanization, Reuters reported.

Many cases go unrecorded, but in 2022 4.2 million cases were reported worldwide and public health officials have warned that near-record levels of transmission are expected this year. Bangladesh is currently experiencing its worst-ever outbreak, with more than 1,000 deaths.

“We need to talk much more proactively about dengue,” Jeremy Farrar, an infectious diseases specialist who joined the World Health Organization in May this year, told Reuters.

“We need to really prepare countries for how they will deal with the additional pressure that will come… in the future in many, many big cities.”

Farrar previously spent 18 years working in Vietnam on tropical diseases including dengue. He later headed up the Wellcome Trust global health charity and advised the UK government on its COVID-19 response before joining the WHO in May this year.

Farrar said the infection is likely to “take off” and become endemic in parts of the United States, Europe and Africa - all regions where there has already been some limited local transmission - as global warming makes new areas hospitable to the mosquitoes that spread it. That will put acute pressure on hospital systems in many countries, he warned.

“The clinical care is really intensive, it requires a high ratio of nurses to patients,” he said. “I really worry when this becomes a big issue in sub-Saharan Africa.”

Most people who get dengue do not have symptoms, meaning case rates are thought to be far higher than the reported numbers. Those who do can experience fever, muscle spasms and joint pain so severe it is known as “break-bone fever.” In severe cases – less than 1% - it can be fatal.

There is no specific treatment for dengue, although there is a vaccine available. Earlier this week, the WHO recommended Takeda Pharmaceuticals' Qdenga vaccine for children aged 6 to 16 in areas where the infection is a significant public health problem.

Qdenga is also approved by the EU regulator, but Takeda withdrew its application in the United States earlier this year, citing data collection issues. Takeda said it was still in talks with the U.S. Food and Drug Administration about the vaccine.

Preparing new regions of the world to deal with dengue means ensuring that any public health funds get spent in the right areas, Farrar said, including on the best way to control the mosquito.

Dengue is spread by infected Aedes aegypti mosquitoes, which behave differently to the malaria-carrying kind. For example, they bite people indoors, and they bite all day rather than overnight. They also breed in very shallow water.

Farrar said proper prevention would include triaging plans for hospitals as well as scientific innovation alongside other key factors, such as urban planning, to avoid areas of standing water near or in houses.

“We need to combine different sectors that are not used to working together,” he said.

The Ministry of Public Health says nearly 25,000 people in the country lose their sight every year.

Marking World Sight Day on Thursday in Kabul, health officials said that 1.5 million people contract eye diseases every year.

The ministry officials added that many people in remote areas suffer from eye diseases.

“Nearly 1.5 million people suffer from visual impairment every year. In Afghanistan, about 25,000 people lose their sight every year,” said Abdul Wali Haqqani, Deputy Minister of Public Health.

“In the world, more than two billion people are visually impaired,” said Naimullah Safi, representative of the World Health Organization.

According to health officials, since the beginning of this year, nearly 4,000 eye operations have been performed in various provinces.

Meanwhile, Afghanistan is also facing a shortage of ophthalmologists. There are only 300 specialists registered in the country, but not all are practicing ophthalmologists. Many have retired, while others have left the country.

Afghanistan’s health ministry convenes urgent meeting on disease outbreak in Parwan

Haqqani ordered specialized health teams to be deployed to the affected area and ordered a follow up meeting to be convened with World Health Organization representatives and other health partners.

The Islamic Emirate of Afghanistan (IEA) called an urgent meeting Sunday of senior health-care officials to address the outbreak of acute diarrhea in the Kafshan Valley of Ghurbund district in Parwan province.

This comes after concerns were raised last week by Parwan officials who confirmed that over 500 people had come down with a mystery illness.

Hekmatullah Shamim, the governor’s spokesman, said the affected people had all fallen ill over four-days.

The IEA’s Ministry of Health sent officials to the affected area and blood samples were taken from patients for analysis.

In a statement issued Sunday by the ministry, the deputy minister for health services Mawlawi Abdulwali Haqqani called the meeting, which was attended by central directors from the ministry, representatives from the infectious disease hospital and other experts.

Haqqani ordered specialized health teams to be deployed to the affected area and ordered a follow up meeting to be convened with World Health Organization representatives and other health partners.

The teams deployed to the area will focus on raising public awareness, assessing the health status of patients, and ensuring the provision of comprehensive medical facilities for both patients and local residents.

“These efforts are critical to facilitate urgent interventions necessary to mitigate the outbreak,” the statement read.

According to the World Health Organization (WHO), Afghanistan is grappling with significant health challenges marked by a fragile healthcare system and unequal access to services, particularly in rural areas.

In their latest report published last week, the Health Cluster Afghanistan Bulletin for August 2024, the WHO said there is a looming threat of disease outbreaks, including acute watery diarrhea (AWD), measles, Crimean Congo Hemorrhagic Fever (CCHF), dengue fever, COVID-19, pertussis (whooping cough), and malaria.

In August 2024, a total of 402,920 cases of acute diarrheal disease were reported, representing 14.6 percent of total consultations.

Out of the total acute diarrheal disease cases, 23,801 new AWD, with dehydration, cases were reported in August, resulting in 10 deaths.

So far this year, total of 125,471 AWD cases with dehydration and 60 associated deaths were reported, the WHO report stated.

Afghanistan’s health minister says health-care should not be politicized

Published

on

Acting Minister of Public Health, Noor Jalal Jalali, says the issue of health should not be politicized given that Afghanistan has a vulnerable health-care sector and needs international aid.

Addressing a ceremony to mark the opening of a new children’s immunization center, Jalali said the death rate of children in Afghanistan is still high and international organizations should help health officials reduce this rate.

“I mostly say that health and politics should be separated. International partners who claim the rights of mothers and children [should be ensured] should cooperate a lot in the field of health,” said Jalali.

He added that 17 health centers will be built in districts across the country this solar year.

Meanwhile, Deputy Minister for Health Services Abdul Wali Haqqani also spoke at the event and said about two million children have not yet been vaccinated.

According to him, 900,000 children will receive vaccines over the next 18 months.

A representative of UNICEF also stressed the need for the complete eradication of polio in Afghanistan.

“Afghanistan is one of the countries where polio cases still exist. Therefore, this program is an opportunity to reach out to children who have missed vaccination [campaigns], and we strive to protect these children and expand this program to the highest level in the future,” said the UNICEF representative.

According to official data, between four and five million children benefit from the polio program every year.

The World Health Organization (WHO) recently confirmed 18 new cases of polio infection in the country so far this year, a significant increase from the six cases reported in 2023.

Local healthcare workers say these numbers could be higher as many cases will not yet have been detected.
