WHO warns of dengue risk as global warming pushes cases near historic highs

Published

on

The World Health Organization warned on Friday that cases of dengue fever could reach close to record highs this year, partly due to global warming benefiting mosquitoes that spread it.

Dengue rates are rising globally, with reported cases since 2000 up eight-fold to 4.2 million in 2022, WHO said.

The disease was found in Sudan's capital Khartoum for the first time on record, according to a health ministry report in March, while Europe has reported a surge in cases and Peru declared a state of emergency in most regions, Reuters reported.

In January, WHO warned that dengue is the world's fastest-spreading tropical disease and represents a "pandemic threat".

About half of the world's population is now at risk, Dr. Raman Velayudhan, a specialist at the WHO's control of neglected tropical diseases department, told journalists in Geneva on Friday.

Reported cases to WHO hit an all-time high in 2019 with 5.2 million cases in 129 countries, said Velayudhan via a video link. This year the world is on track for "4 million plus" cases, depending mostly on the Asian monsoon season.

Already, close to 3 million cases have been reported in the Americas, he said, adding there was concern about the southern spread to Bolivia, Paraguay and Peru.

Argentina, which has faced one of its worst outbreaks of dengue in recent years, is sterilizing mosquitoes using radiation that alters their DNA before releasing them into the wild.

"The American region certainly shows it is bad and we hope the Asian region may be able to control it," Velayudhan said.

WHO says reported cases of the disease, which causes fever and muscle pain, represent just a fraction of the total number of global infections since most cases are asymptomatic. It is fatal in less than 1% of people.

A warmer climate is thought to help the mosquitoes multiply faster and enable the virus to multiply within their bodies. Velayudhan cited the increased movement of goods and people and urbanization and associated problems with sanitation as other factors behind the increase.

Asked how the heatwave affecting the northern hemisphere would affect the spread of the disease, he said it was too soon to tell.

Temperatures over 45 degrees Celsius "should kill the mosquito more than breeding it, but the mosquito is a very clever insect and it can breed in water storage containers where the temperature doesn't rise that high."

Muttaqi appeals to WHO to help strengthen Afghanistan’s health sector

Hanan Balkhy, the World Health Organization’s director for the Eastern Mediterranean Regional Office, met in Kabul this week for talks with Amir Khan Muttaqi, the IEA’s foreign minister

The Islamic Emirate has appealed to the World Health Organization to equip and strengthen Afghanistan’s health sector and to support Afghanistan’s pharmaceutical production sector. 

Dr. Hanan Balkhy, the World Health Organization's director for the Eastern Mediterranean Regional Office, met in Kabul this week for talks with Amir Khan Muttaqi, the IEA’s foreign minister. 

During the meeting, Muttaqi asked the World Health Organization to assist Afghanistan and to help it achieve self-sufficiency in the pharmaceutical production sector. 

Balkhy meanwhile said that he was trying to garner support for Afghanistan from leading health experts around the world. 

Christopher Elias, head of global development for the Bill Gates Foundation, also attended this meeting and said his organization was trying to take effective measures to eliminate the polio virus in Afghanistan. 

Polio cases increase

Elias’ comment comes after the WHO stated that the forced repatriation of Afghan nationals from Pakistan was a “major setback” for polio eradication efforts and that it contributed to the regional resurgence of the disease.

Pakistan and Afghanistan are the only two polio-endemic nations in the world and so far this year, the two countries have reported 49 and 23 cases respectively; up from only six cases each in 2023.

The latest case in Pakistan was confirmed last week in the southwestern province of Balochistan, which sits on the Afghan border and accounts for half the cases reported in 2024.

The United Nations High Commissioner for Refugees has said that Pakistan's crackdown on undocumented foreign nationals has resulted in more than 730,000 Afghan migrants returning to Afghanistan since August 2023.

UNICEF ensures 6.1 million people have access to basic health services in Afghanistan

Published

More than six million people accessed essential health and nutrition services at UNICEF-supported health facilities last month, the UN agency said in its latest Humanitarian Situation Report for September 1 to 30.

UNICEF said of the 6.1 million people who accessed essential health and nutrition services, half of them were children under the age of five.

In addition, 50 schools in 10 provinces gained access to safe water, handwashing facilities, and newly constructed or rehabilitated toilet facilities.

However, as of September, UNICEF’s Humanitarian Action for Children (HAC) appeal for children in Afghanistan is only 41 percent funded.

Afghanistan remains one of the world’s largest humanitarian crises, with 23.7 million people in need of humanitarian assistance following decades of conflict, extreme climate shocks, and severe economic decline.

UNICEF also stated that this year, 33 percent of the population receives most of their income from unsustainable income sources, compared to 26 percent in 2023.

Polio vaccination campaign kicks off in Afghanistan

Published

on

Public Health Ministry officials have confirmed that a polio vaccine campaign across 16 provinces was launched on Monday.

Sharaft Zaman Amarkhil, the spokesperson of the Ministry of Public Health, says that the campaign got underway on Monday in a number of provinces including Kabul, Kandahar, Helmand, Uruzgan, Zabul, Farah, Nangarhar, Laghman, Kunar, Nuristan and some other provinces.

Amarkhil said the campaign will last for three days and an estimated 6.2 million children under the age of five will receive the anti-polio vaccine.

Zaman called on parents, religious scholars and ethnic elders to cooperate with the ministry's vaccinators in implementing the anti-polio vaccination campaign for children under five years old in the mentioned provinces.

The World Health Organization meanwhile published its latest Polio Bulletin on Monday and confirmed Afghanistan has recorded 23 cases of Wild Polio Virus so far this year.

Pakistan meanwhile reported two new cases this week - one in Khyber Pakhtunkhwa province and the other in Balochistan province.

Pakistan has recorded a total of 41 cases of polio so far this year, bringing the total between the two countries to 64, against last year’s total of 12 (Afghanistan 6 and Pakistan 6).
World Polio Day

Marking World Polio Day last week, UNICEF pointed out that the current data issues a stark warning that the life-threatening disease continues to thrive in areas where conflict, natural disasters, humanitarian crises, and other destabilizing factors make it difficult to deliver critical healthcare.

“In conflict, children face more than bombs and bullets; they are at risk of deadly diseases that should no longer exist,” said UNICEF Executive Director Catherine Russell.

“In many countries, we are witnessing the collapse of healthcare systems, destruction of water and sanitation infrastructure, and the displacement of families, triggering a resurgence of diseases like polio. Children are being left paralyzed, unable to walk, play, or attend school."

A global decline in childhood immunization has also led to an increase in polio outbreaks, including in countries that had been polio-free for decades.

Nowhere is this more evident than in conflict-affected areas, with 15 out of 21 such countries – including Afghanistan, Democratic Republic of Congo, Somalia, South Sudan, and Yemen – currently battling polio.

In recent months, UNICEF and partners have intensified emergency responses to surges in polio outbreaks.

In Gaza, for example, UNICEF, in partnership with WHO, reached nearly 600,000 children under 10 years during the first round of a polio vaccination campaign in mid-September. The second and final round has been successfully implemented in south and central Gaza, but renewed mass displacement and bombings have delayed the process in the north.

The campaign follows the return of polio to Gaza for the first time in 25 years.
